How Runtime is run.Four controls, every day.
- AccessProduction is reached only by the people and systems that operate it; actions on your resources are recorded.
- ChangeEvery change is in version control and passes formatting, advisory, type, build and test checks before it is pushed.
- VulnerabilitiesDependencies are checked against published advisories; reports go to security@withruntime.com.
- MonitoringSecurity events are reviewed automatically every ten minutes, and logs are kept a year off the servers.
If something fails.Backed up, and the restore tested.

Asked in every review.Answered here.
Anything else? Ask us
Is there single sign-on?
Yes, over SAML or OIDC, with directory sync over SCIM, on the Scale and Enterprise plans. More
Can we require two-step sign-in?
With a passkey or an authenticator app, which an owner can require of everyone in the account, and sign-in with a passkey alone (two-step sign-in).
What roles and keys are there?
Four roles (owner, admin, developer, billing), read-only keys, compartments that wall a group of keys off from the rest of the account, and daily spending limits per key (keys).
Is every change recorded?
Every change to the account, who made it, from where and how: kept a year with export on Scale, seven years on Enterprise. More
How is uptime checked?
Publishes the API's uptime, checked from outside every two minutes, and a real sandbox started from outside every ten (status). More
What uptime is promised?
Every month, with service credit paid automatically when a month falls short (uptime promise). More
Can the database be restored?
Can be rewound to any moment in the last 24 hours, and a sealed copy goes off-site every night and is kept 30 days, locked so it cannot be deleted early. A restore from that copy was last tested on 27 September 2026.
Are volumes backed up?
A snapshot survives loss of its server once its off-server copy is checked, shown by backedUp: true (storage and backups). Every week one backed-up item is restored and checked against the checksum recorded when it was saved.
Who can reach production?
Production is reached only by the people and systems that operate it, and actions on customers' resources are recorded.
How do changes reach production?
Changes are in version control and pass repository checks before they are pushed. The checks cover formatting, dependency advisories, linting, types, builds and tests for the affected packages. A production website release passes the full check; going live is a separate, deliberate step.
What is monitored?
Security events, such as an account locked after wrong two-step codes, every sign-in to the operator's dashboard and a backup that did not complete, are reviewed automatically every ten minutes, and the operator is alerted to anything unusual. The servers' sign-in logs and the log of every release signed are copied off the servers every day and kept a year, where the key that writes them cannot delete them.
What happens in an incident?
A written procedure covers containing an incident, keeping the evidence, finding who is affected and telling them without undue delay, as the data processing addendum promises.
Who else handles our data?
Every company that handles customer data is on the subprocessors page before it starts, under a data processing agreement. More
How do we report a vulnerability?
Write to security@withruntime.com before you test anything. Write again with what you find. Testing Runtime's own servers, network or other accounts without agreeing it with us first breaks the acceptable use policy. We may suspend the account. A report helps most when it includes three things. Include the steps to reproduce the problem. Include the sandbox or request ids involved. Include the time, with its time zone. Please give us a reasonable time to fix a problem before you describe it in public. The same address is in /.well-known/security.txt.
