Dedicated security recipes for SQL injection fixes, input validation hardening, XSS prevention, and vulnerability remediation.

Framework Migrations

Automated framework upgrades — Flask to FastAPI, Rails version upgrades, Spring Boot modernization, and more.

GitHub-Native PR Workflow

Automatically creates pull requests with detailed diffs, descriptions, and approval gates. No manual steps required.

Automated Test Validation

Every refactoring is validated against your existing test suite. No changes ship without passing tests.

RBAC & Multi-Tenant

OIDC JWT + API key auth, 4-role hierarchy, PostgreSQL row-level security, self-service API key management, and immutable audit trail.

Optional Approval Gates

Human-in-the-loop approval via HumanLayer before PRs are created. Full control over what ships to your codebase.

Full Observability

Real-time job tracking with per-file status, Prometheus metrics, Sentry error tracking, and OpenTelemetry distributed tracing.

Reforge API Workflow

Submit refactoring jobs, track progress, and retrieve artifacts — all through a clean REST API.

All endpoints require an API key via the X-API-Key header. Full API reference available in the docs.
