RouteSafe turns your public route manifest into a versioned contract. Every PR gets a check listing every slug the deploy would break — before the merge button lights up.

RouteSafe ships as a GitHub Action / GitLab CI / CircleCI plugin plus a thin web dashboard. The CI plugin diffs the prior deploy's route manifest against the PR's build artifact and annotates the PR with every slug that will 404 after merge; the dashboard stores manifest history, generates redirect stubs, and tracks per-repo health.
No source code leaves your CI — the action transmits only the route manifest: path strings, status codes, and content hashes.

RouteSafe reads a route manifest JSON file your build process emits. Most modern frameworks (Next.js, Astro, Nuxt, Remix) can generate this as a build artifact. For frameworks without native support, RouteSafe ships a CLI crawler that walks your build output directory and generates the manifest.
The PR check blocks and lists every offending slug with a 'Generate redirect stub' action. One click generates a redirect stub (301 configuration entry) and commits it back to the branch. RouteSafe re-checks the manifest after the commit — if the stub resolves the slug, the check passes.
Under 8 seconds P95 for repos with fewer than 10,000 routes. The manifest diff is a bloom-filter comparison against the production snapshot — not a full crawl.
You can mark a slug as explicitly removed in the manifest or via an override in the workflow configuration. RouteSafe will mark it as acknowledged, not broken, and the check passes.
GitHub Actions at launch. GitLab CI and CircleCI adapters are in Phase 3. Apply for the design-partner cohort and you can influence the Phase 3 priority order.
RouteSafe handles routes with known static segments. Fully dynamic catch-all routes generated at request time are documented as out-of-scope — you can supplement the manifest with a manual override file for edge cases.
Design-partner repos get the first repo gated free while we co-develop with your pipeline team. Apply and we'll confirm onboarding within 48 hours.
Who this is for
30–300-person SaaS or headless-CMS-driven marketing shops in the US (UK/EU secondary). Buyer: Engineering Manager or VP Eng. User: Staff/Senior Engineer who merges PRs on a shared route tree. Stack signal: GitHub Actions + Next.js/Astro/Remix + Vercel/Netlify.
Who this is NOT for
RouteSafe is NOT for teams with pure backend APIs or internal tools that have no SEO surface, companies running deploy cycles longer than two weeks where a manual redirect review is already practical, or shops on air-gapped GitLab that cannot egress a route manifest. It is also not the right tool for content-only sites where all slug changes happen in a CMS and never pass through a PR — until the phase-4 CMS webhook integration ships, those teams will miss the gate entirely.
What we're validating now
Apply as a design partner
Free 48-hour manual route audit for design partners ($299 one-time for others): we diff the last three deploys, identify every orphaned slug, and deliver a redirects.json stub + gap summary — all from read-only repo access, no source code.
Pricing under test
Solo $49/mo (1 repo, no EM sign-off needed); Team $199/mo (10 repos, below $250 procurement threshold); Growth $499/mo (50 repos + SOC 2 evidence packet); Enterprise custom $1,500–$3,000+/mo (self-hosted + SSO + SLA, phase-4 only).
