The runtime-aware merge gate for AI-generated code.

autter installs on your repository in one click and becomes a required check
on every pull request. No workflow changes. No new commands. It runs
automatically and posts its findings directly onto the PR.

What autter does on every pull request

Blast Radius Analysis
Maps the full downstream impact of the proposed change across your entire
codebase. Flags when authentication, payments, database schema, or public
API endpoints are in the blast zone.

AI Slop Detection
Catches the specific failure patterns that AI coding tools produce at scale:
hallucinated imports, placeholder logic, removed auth checks, cross-language
leakage, and generic variable names that signal unreviewed generation.

Static Security Scanning
OWASP-aligned detection for SQL injection, hardcoded secrets, command
injection, and XSS patterns. Dependency vulnerability scanning via the OSV
database.

Behavioral Regression Detection
Catches regressions no linter will find: inverted conditions, removed
transaction boundaries, and broken function contracts that only surface in
production.

Execution Validation
Spins up an ephemeral copy of your application via Daytona, runs your
existing test suite against the PR branch, and compares results against the
base. If the PR introduces new failures, the merge is blocked.

Migration Safety
Spins up an ephemeral database branch via Neon, applies the migration,
inserts synthetic test data, and replays real query patterns from your
codebase. Catches data-loss migrations before they touch a production row.

What reviewers see

Every PR gets a structured risk summary: what the change does, how far it
reaches, what was found, and a clear verdict on whether to block or allow
the merge. 40 minutes of uncertain manual analysis becomes 5 minutes of
confident, data-backed decision-making.

Who it is for

Engineering teams and open source maintainers shipping AI-generated code at
scale. If your team uses Cursor, Copilot, Lovable, Bolt, or any other AI
coding tool, autter is the gate between that output and your production
codebase.
