Everyone automated the noise. We automated the judgment.
AI writes code faster than any team can review it — so the bots bury your pull requests in confident guesses, and you stop reading. Santinel reads every line, and speaks only when a compiler, your codebase's own structure, or repeated proof agrees it's right.
Works with GitHub and GitLab — as a PR bot or in your CI.
Guesses don't ship.
Same pull request. Two very different reviews.

Three ways to prove a finding
A finding ships only when at least one objective channel confirms it.
Types & tools
Compilers, type-checkers, linters, secret and dependency scanners run first — sub-second, no model in the loop. If the tool is certain, so are we.
$ tsc --noEmit -> error TS2345Your structure
A versioned map of your code's structure — across every repository. Santinel diffs the structure between commits and catches contracts that break across services, even ones nobody declared.
structure diff: endpoint shape changed · 3 callers staleRepeated agreement
For the semantic tail, many independent passes must agree — and survive an objective check that tries to refute them — before a word reaches your PR.
8 passes agree · refuter found no counter-exampleCatches contracts breaking ACROSS repositories
An endpoint changes shape in one repo; the client that calls it lives in another. Santinel maps your whole fleet's structure and flags the break before merge — even when nobody declared the dependency.
body: { amount: total * 100 }What you get
Cross-repo contract drift
Catches a client calling an endpoint that changed shape — across repositories, with zero manual wiring.
Docs and requirements vs. code
Flags when code drifts from its own documentation, or from the behavior your spec promised.
Deterministic first pass
Compilers, type-checkers, linters and SAST across many languages — sub-second, no model in the loop.
An agent that verifies its own work
Writes code in an isolated sandbox, gates every draft, and opens a PR only after it passes.
Propose, confirm, apply
Suggests a fix and shows exactly what it changes — then applies it on your approval. Never a silent edit.
Principle-aware review
Explains why something breaks a principle — SOLID, YAGNI, KISS — not just that a line looks off.
Learns per repository
Sharpens on the findings your team confirms. What it learns never crosses a repository boundary.
Native board, or your CI
Run delivery on a built-in board with sprints — or drop Santinel into GitHub Actions or GitLab CI. Locked to neither.
From ticket to merged — with gates that don't blink
A workflow enforced by git hooks: branch per task, a regression test before the fix, a sub-second deterministic pre-push gate that blocks on errors, and an auto-review on every PR.
