Foundation Machines

Foundation Machines builds AI products for software security. Our first product is Sebastion AI, a GitHub App that reviews every pull request for security issues, and an underlying API gateway for teams that want programmatic access to the same engine.

Sebastion AI, security review for every pull request

Sebastion AI is a GitHub App. Install it on a repo and every pull request is reviewed by an autonomous security auditor. Findings land back in the repository as a GitHub issue, usually within 60 seconds of the push.

The typical UX:

1. Install the app at github.com/apps/sebastionai and pick the repositories you want covered.
2. Push a pull request. No config required; Sebastion picks the model for you based on your plan.
3. Read the findings. A new GitHub issue is opened with severity-tagged findings, file/line references and concrete fixes.

Plans are billed per developer, not per token and only developers who actually author pull requests count toward billing. See billing for the per-tier breakdown.

API access

For power users, CI integrations and enterprise teams that want to call the same engine programmatically, we expose an OpenAI-compatible API at https://api.foundationmachines.ai/v1.

• OpenAI-compatible chat at POST /v1/chat/completions against a curated set of frontier models, see models.
• Sebastion AI: live security audit endpoint at POST /v1/audit. See the audit reference.
• Foundation Score: a public security grade for OSS repos.
