Blacksmith Contact Information
Blacksmith Software Inc. sells CI infrastructure: drop-in runners for GitHub Actions, with caching add-ons. Usage is billed per minute of runner time, with a monthly free allowance per GitHub organization, and card payments go through Stripe. Blacksmith said in June 2026 that runners keep running past the free allowance and the usage is invoiced, even with no card on file. Support tickets are opened from the Blacksmith dashboard; its Terms of Service set out no cancellation procedure or refund policy. No published complaint reports are currently linked to this profile.

Complaint and review record
No published complaint reports are currently linked to this profile.
Trustpilot. The unclaimed Trustpilot page for blacksmith.sh holds one review, and it describes a hamburger restaurant in Sweden, not this CI company.
Free-tier invoice complaint. A June 2026 blog post by Allen Pike of Forestwalk Labs, which makes Powerplant, objects to billing after the free minutes run out. He says his team tried Blacksmith on its "try for free" and "no credit card required" offer. They received emails asking them to add a card "to avoid disruptions to your service", a notice of $500.60 spent that month, then an invoice and an overdue notice for $1,081.45. Support told them the "disruption" wording referred to accounts being flagged for review, such as for suspicious activity, not to automatic suspension, and that workflows are not cut off when the free tier is exceeded and keep accruing usage at published rates. He writes that this was surprising rather than dishonest, but calls it a bad practice, describes a prickly support exchange and suggests winding use down before the trial limit. He also says the team found the service faster than GitHub Actions and would probably go back. His postscript says Blacksmith offered to credit the overage and to share changes to its pricing and overage wording. The figures are his.
Blacksmith's response. In the Hacker News discussion of the post, a Blacksmith product employee wrote that the company has never pursued such invoices, voids them for users who did not mean to continue past the free tier and often gives credits to those who did, and should have offered to void this one. He also wrote that the company gets support cases every month from users confused about their invoice and that it did a bad job of communicating the policy. He said the free-usage email wording had been changed and that a setting to stop runs when free minutes run out was being built, with continued running likely to stay the default.
Service incidents. Blacksmith publishes current status and its full incident history at status.blacksmith.sh. Examples from its own notices: delayed job starts on macOS runners (October 20–21, 2026, attributed to reduced capacity at an upstream provider); a backend degradation that slowed jobs and caused caching failures (September 29, 2026); job failures and delays during GitHub outages and webhook incidents (August 17–18, 2026); and a storage degradation in its us-west region (August 13–14, 2026, lasting about 30 hours), when a power and cooling problem at its datacenter provider took capacity offline, disabled caching there and slowed jobs in other regions. These descriptions are the company's own.

What it is. Blacksmith sells CI infrastructure for GitHub Actions. Its home page calls the service "a dead simple, drop-in replacement that costs 60% less than GitHub runners" (company claim).
Prices. The pricing page lists pay-as-you-go rates for the smallest runner of each type (2 vCPU; 6 vCPU for macOS): $0.004/min (Ubuntu x64), $0.0025/min (Ubuntu ARM), $0.008/min (Windows x64) and $0.08/min (macOS M4). Larger runners cost proportionally more: the rate doubles each time the vCPU count doubles, so an 8 vCPU Ubuntu x64 runner is $0.016/min. The free allowance is 3,000 Ubuntu x64 2 vCPU minutes per GitHub organization per month. The pricing page prints "3,000 free min/mo." on its plan cards, but the documentation counts those minutes in x64 2 vCPU equivalents across all runner types, so other runners use them up faster (one Windows 2 vCPU minute counts as 2 of those minutes, one macOS 6 vCPU minute as 20, one ARM 2 vCPU minute as 0.625), so it covers, for example, about 150 minutes on the smallest macOS runner. Add-ons: Docker layer caching and sticky disks at "+$0.50/GB/mo." (listed for the Ubuntu runners) and static IPs at "+$100/IP/mo." (listed for Ubuntu and Windows). The documentation prices the Codesmith agent and Proof separately: $0.002 per vCPU per minute of sandbox compute, plus tokens at the model provider's rate + $0.20 per million. The savings percentages on that page are the company's, "based on GitHub's per-minute rate and an estimated 2x faster runtime on Blacksmith." The Enterprise plan has no listed price ("Contact our team"). A startup discount is offered to companies with under 100 employees, under $50 million raised and under 5 years in business; you sign up first and then contact the company to apply.
How billing works. The Terms of Service (effective July 20th, 2026) make you responsible for "all fees, including taxes, associated with Your use of the Services." The home and pricing pages say no credit card is required to try the service, while the Terms list adding a valid payment method, processed through Stripe, as part of account setup. Entering card details authorizes Blacksmith "to charge Your credit card for usage fees"; customers on invoice-based agreements pay under those invoicing terms. Blacksmith works only with GitHub organizations, not personal repositories: you install its GitHub app and change a job's runs-on label (for example from ubuntu-latest to blacksmith-2vcpu-ubuntu-2404), and minutes on those runners are billed. The free minutes are not a hard stop: Blacksmith support told a customer in 2026 that workflows keep running past the free tier and accrue usage at published rates, so a team with no card on file can still receive an invoice. The Codesmith billing documentation says you are invoiced the first time combined monthly usage, runners included, crosses $100, and that if a charge fails, Codesmith access may be restricted while CI runners continue to run and accrue charges; invoices can be paid from Billing and Usage in the dashboard.
More detailShow less
The Terms' payment section sets no specific due date, although an overdue notice quoted by one customer said payment terms "require payment upon invoice generation." Section 9 of the Terms lets Blacksmith suspend or terminate access if you are in arrears.
Keeping track of spending. The Usage & Billing page in the Blacksmith dashboard breaks down current usage. In the dashboard settings you can set a monthly spending threshold; Blacksmith emails the account's primary address when spending goes over it. The documentation describes this as an email alert, not a limit that stops jobs. In June 2026 a Blacksmith employee said a setting to stop runs when free minutes run out was being built, with continued running likely to stay the default. The documentation does not describe such a setting, so check your dashboard settings and do not assume a hard stop. Codesmith has its own monthly spend limit in Settings, and a Codesmith session pauses the first time it reaches $200 unless that pause is turned off.
More detailShow less
The Blacksmith CLI command blacksmith usage reports jobs, billable minutes and estimated cost for the last 30 days by default (up to 90 days), with breakdowns by day, runner type, repo, workflow or job; blacksmith usage storage reports sticky-disk storage and its estimated cost.
Cancelling and refunds. Blacksmith's pricing page, Terms of Service and documentation describe no cancellation procedure or refund policy. The per-minute runner charge applies to jobs that run on Blacksmith runners, so moving your workflows' runs-on labels back to GitHub-hosted runners means new jobs no longer use them. Sticky disks are billed per GB per month; the documentation says a sticky disk is deleted automatically after 7 days in which no job uses it. Static IPs are set up through support, so ask support to remove them. Codesmith and Proof are billed separately: stop using them, or set the Codesmith spend limit in Settings. To end the relationship fully, uninstall the Blacksmith GitHub app from your organization and email [email protected], the Terms' address for notices, asking for your account to be closed. In the same email, ask for your Customer Content (the code, files and other data you put on the service) to be deleted; the Terms say Blacksmith "will comply with such request within 30 days of notice," a commitment that covers the content, not the account. If you can reach the dashboard, open a ticket as well. For a refund or billing dispute, write to [email protected] (or your customer success representative) and keep the written answer. If you were invoiced after free minutes ran out with no card on file and did not mean to continue, reply in writing to [email protected] and say so: a Blacksmith employee wrote in June 2026 that the company voids such invoices. If you paid by card and cannot resolve a charge with the company, your card issuer handles disputes; under the federal Fair Credit Billing Act, a written billing-error dispute must reach the issuer within 60 days after the first bill showing the error was sent. A debit card falls under a different law, the Electronic Fund Transfer Act: tell your bank within 60 days after the statement showing the charge was sent.

Who to contact. Blacksmith does not publish a customer service phone number. Support requests go through the dashboard ("Report an issue"). The Support Terms say: "Tickets for Incidents must be submitted through the Blacksmith dashboard" and "Email is not a designated support channel"; [email protected] is the fallback if you cannot access the dashboard, and response-time commitments apply only to tickets filed in the dashboard. Billing questions: [email protected] "or to your customer success representative." General questions, media and partnerships: [email protected]. Standard support is included for all customers at no extra charge. Premium Support is available to customers who buy the add-on or sign an annual or committed-spend contract, at the greater of $250 a month or 5% of monthly Blacksmith spend; Premium and Enterprise support get round-the-clock responses on business-critical incidents; the 99.9% Uptime SLA applies only to Enterprise Support. The support page says that outside Enterprise, "support is available on a best-effort basis." Service status: status.blacksmith.sh.

Frequently Asked Questions
How much does Blacksmith cost?
For the smallest runner of each type (2 vCPU; 6 vCPU for macOS), the pricing page lists $0.004/min for Ubuntu x64, $0.0025/min for Ubuntu ARM, $0.008/min for Windows x64 and $0.08/min for macOS M4; the rate doubles each time the vCPU count doubles. Each GitHub organization gets 3,000 free Ubuntu x64 2 vCPU minutes a month. The pricing page prints "3,000 free min/mo." on its plan cards, but the documentation counts those minutes in x64 2 vCPU equivalents, so Windows, macOS and larger runners use the allowance up faster (about 150 minutes on the smallest macOS runner). Add-ons include Docker layer caching and sticky disks at $0.50/GB/month and static IPs at $100/IP/month. The documentation prices the Codesmith agent and Proof separately: $0.002 per vCPU per minute plus tokens at the model provider's rate + $0.20 per million. Enterprise pricing is not published.
How do I cancel Blacksmith?
Blacksmith's Terms of Service, pricing page and documentation do not describe a cancellation procedure. The per-minute runner charge applies to jobs that run on Blacksmith runners, so moving your workflows' runs-on labels back to GitHub-hosted runners means new jobs no longer use them. Sticky disks are billed per GB per month and, per the documentation, are deleted automatically after 7 days without use. Static IPs are set up through support, so ask support to remove them. Codesmith and Proof are billed separately: stop using them, or set the Codesmith spend limit in Settings. To close the account, uninstall the Blacksmith GitHub app from your organization and email [email protected], the Terms' address for notices, asking for the account to be closed and your Customer Content (the code, files and other data you put on the service) deleted; keep the reply. If you can reach the dashboard, open a ticket with Report an issue as well. The Terms promise action within 30 days on the content deletion; they make no such promise about closing an account.
Does Blacksmith give refunds?
Blacksmith does not publish a refund policy, and its Terms of Service (effective July 20th, 2026) do not address refunds. Send a refund request or billing dispute in writing to [email protected] (or your customer success representative), naming the charge, the date and the reason, and keep the reply. You can check the billed minutes behind a charge with the CLI command blacksmith usage. In June 2026 a Blacksmith product employee wrote on Hacker News that the company voids invoices for users who did not mean to continue past the free tier and often gives credits to those who did.
How do I contact Blacksmith support?
Support tickets are opened from the Blacksmith dashboard. The Support Terms say email is not a designated support channel; [email protected] is the fallback if you cannot access the dashboard. Response-time commitments apply only to tickets filed in the dashboard. Billing: [email protected]. Enterprise customers also get a shared Slack channel, but the Support Terms say it is not the channel for opening or tracking support requests.
How is Blacksmith billed?
The home and pricing pages say no credit card is required to try Blacksmith; the Terms list adding a payment method as part of account setup. Blacksmith support said in 2026 that workflows keep running past the free tier and accrue usage at published rates, so an organization with no card on file can still be invoiced. The Codesmith billing documentation says you are invoiced the first time combined monthly usage, runners included, crosses $100. The Terms say payment methods such as credit cards are processed through Stripe and that providing card details authorizes Blacksmith to charge for usage fees; invoice-based agreements follow their own invoicing terms. Runner time is billed per minute and storage add-ons per GB per month. The CLI command blacksmith usage shows billable minutes and estimated cost, and a monthly spending threshold in the dashboard settings triggers an email alert when spending goes over it; the alert does not stop jobs.
What support do non-enterprise customers get?
The Support Terms say Standard support is available to all customers at no additional charge, and Premium to customers with a Premium add-on or an annual or committed-spend contract, priced at the greater of $250 a month or 5% of monthly Blacksmith spend. The support page says that outside Enterprise, support is on a best-effort basis. The published response targets cover only Premium and Enterprise tickets opened in the dashboard: for business-critical incidents, every response within 2 hours (Premium) or 30 minutes (Enterprise), around the clock; for general issues, a first response within 24 business hours (Premium) or 12 business hours (Enterprise). The 99.9% Uptime SLA and service credits are for Enterprise Support only.

The Privacy Policy names Blacksmith Software Inc., 95 Third Street, 2nd Floor, San Francisco CA, 94103, as its owner and data controller. Y Combinator lists the company as founded in 2024 by Aditya (JP) Jayaprakash (CEO), Aayush Shah and Aditya Maru. It is a private, venture-backed company, and its Terms and Privacy Policy name no parent company. On October 21, 2026, Cooley, the law firm that advised Blacksmith, announced a $66 million Series C led by Sequoia Capital at a $1 billion valuation, with Premji Invest, Peak XV Partners, GV and Y Combinator also investing.
Where can I check whether Blacksmith is down?
Blacksmith's status page, status.blacksmith.sh, lists current status and past incident notices.
How do I delete my data from Blacksmith?
The Privacy Policy says that on termination or request Blacksmith will delete your data within 30 days; send privacy and deletion requests to [email protected]. The Terms say Customer Content deletion requests are honored within 30 days of notice.
Is Blacksmith a scam?
Blacksmith Software Inc., which gives a San Francisco address in its Privacy Policy, is a company from Y Combinator's Winter 2024 batch that sells GitHub Actions runners billed per minute. A customer's June 2026 blog post describes starting with no credit card, going past the free minutes and receiving an invoice and overdue notice for $1,081.45. The post calls that a bad practice and also says the runners worked and were faster than GitHub's. A Blacksmith product employee replied that the company has never pursued such invoices, voids them for users who did not mean to continue, and gets support cases every month from users confused about their invoice. Blacksmith said in June 2026 that runners keep running after the free minutes end and that an option to stop them was coming; check your dashboard settings and do not assume a hard stop.
Is Blacksmith legit?
Blacksmith Software Inc. sells GitHub Actions runners billed per minute; its Privacy Policy gives the address 95 Third Street, 2nd Floor, San Francisco. It publishes Terms of Service and a public status page with its incident history. Cooley, the law firm that advised it on the round, announced a $66 million Series C led by Sequoia Capital in October 2026. A customer's June 2026 blog post objects to being invoiced for usage past the free minutes, and also says the runners were faster than GitHub's. The only review on the blacksmith.sh Trustpilot page is about a restaurant.
What is Blacksmith's customer service phone number and email address?
Blacksmith does not publish a customer service phone number; its Support page and Terms of Service list none. Open a ticket from the dashboard with Report an issue. The email addresses are [email protected] (if you cannot reach the dashboard), [email protected] (billing questions), [email protected] (general questions, media and partnerships) and [email protected] (privacy, data deletion and formal notices). The only phone numbers in its documents appear in the Privacy Policy and belong to outside data protection representatives in Ireland and the UK, who handle GDPR requests, not customer service.
Is there a lawsuit or class action against Blacksmith?
CourtListener shows no federal case naming Blacksmith Software. The public dispute described on this page is a billing complaint, not a court case. The Terms of Service contain no arbitration clause and no class action waiver. Section 13.1 applies California and US federal law and sets exclusive jurisdiction and venue in the courts located in the City and County of San Francisco, so a lawsuit under the Terms would go there.
