FerrLens · Diff tool is live

Tue, 19 May 2026 22:00:00 GMT

Paste two blobs, get a side-by-side or unified diff with inline character highlights. Whitespace and case toggles. Fully client-side — the URL fragment encodes both inputs so you can share without uploading anything.

FerrLens · Dates now render in your local timezone

Tue, 19 May 2026 19:00:00 GMT

Compressed, opaque share links

Tue, 19 May 2026 16:00:00 GMT

Tue, 19 May 2026 13:35:00 GMT

Encode and decode between text and URL-percent / Base64 / Base64-URL (RFC 4648 §5) / hex, with a single shared input that toggles direction in one click.

FerrLens · Sign in with your FerrLabs account

Tue, 19 May 2026 10:00:00 GMT

Thu, 14 May 2026 17:10:00 GMT

Thu, 14 May 2026 15:10:00 GMT

ferrvault-api is now a proper independently-versioned package with its own Docker image and FerrFlow release lane. End of the "API lives in the app repo but never gets built" era.

FerrTrack · 'My issues' wired to the API + mocked nav stripped

Thu, 14 May 2026 11:10:00 GMT

Inbox no longer fans out one request per project. The 'My issues' page is real data. Subscribed, Active cycle, Roadmap, Docs and Teams are gone until they have a backing data model.

FerrTrack · Org-scoped reads + new GET /v1/issues (breaking)

Thu, 14 May 2026 11:05:00 GMT

Closes a cross-tenant data leak — issue, user, and comment reads now enforce org ownership. Adds /v1/issues with assignee/status/kind filters to replace the Inbox N+1 fan-out.

FerrVault · End-to-end backend rewrite — every screen talks to a real endpoint

Thu, 14 May 2026 11:00:00 GMT

Mocks are gone. Vault edit/delete, secret version history, and the K8s operator token page now hit real APIs. Sidebar trimmed to the three surfaces that actually have a data model.

FerrGrowth · Forms CRUD — create, update, delete, list submissions

Thu, 14 May 2026 09:05:00 GMT

The 'New form' button now opens a real modal instead of doing nothing. POST/PATCH/DELETE on /v1/sites/:slug/forms plus a submissions list endpoint, all org-scoped.

Thu, 14 May 2026 09:00:00 GMT

Every product API (Vault, Track, Growth, Fleet) now falls back to the fl_session HttpOnly cookie when no Authorization header is present. Fixes a hard 401 for all BFF-routed traffic.

Legal pages published — DPA, subprocessors, security

Wed, 13 May 2026 00:00:00 GMT

ferrfleet.com now hosts the standalone Data Processing Addendum, subprocessor list, and security overview in EN and FR.

Tue, 05 May 2026 19:00:00 GMT

POST /v1/telemetry now persists envelopes, organizations and users get a telemetry_opt_out flag, and the toggle endpoints are live in app.ferrlabs.com.

FerrLabs · /telemetry preview of the on-by-default commitment

Tue, 05 May 2026 18:00:00 GMT

New transparency page documenting every event we plan to collect, the hashing scheme, and the opt-out paths. Marked draft until the events actually emit.

FerrLabs · CI i18n + langue désactivée quand pas de miroir

Wed, 29 Apr 2026 18:00:00 GMT

Tous les sites passent par un check CI parité fr/en + résolution de clés. Le toggle FR/EN sur une page sans miroir est désormais visiblement désactivé (strikethrough + tooltip) au lieu de no-op silencieux.

FerrFlow · docs au style Claude

Wed, 29 Apr 2026 16:30:00 GMT
