Toggle features per user, percentage rollout, or environment. No LaunchDarkly SDK, no $75/mo. Just a flag API you call and a dashboard to flip switches.
Most flags tools fall into two camps: free products that harvest your data, or enterprise platforms that cost more than the problem they solve. Embargo exists because neither option makes sense when you just need a reliable feature flag manager under your own control.
An agency managing flags for multiple clients runs one Embargo instance per client on isolated VMs. Each instance gets its own data directory. There is no shared database, no multi-tenant risk, no worry about one client's data appearing in another client's export.
The dashboard opens at /ui and gives you a search bar, status filters, and a create form. Double-click any flag to edit it inline. Behind the dashboard, every operation maps to a REST endpoint under /api/flags. Responses are JSON. Authentication is handled at the network level — put Embargo behind your VPN or reverse proxy, and it serves requests to whoever can reach it.
GET /api/flags — List all flags. Supports ?q=keyword for search and ?status=value for filteringPOST /api/flags — Create a new flag. Send JSON with at least nameGET /api/flags/{id} — Fetch one flag by IDPUT /api/flags/{id} — Update fields on an existing flagDELETE /api/flags/{id} — Remove a flagGET /api/stats — Returns total count and breakdown by statusGET /api/health — Returns {"status":"ok"} for uptime monitoringSelf-hosted feature flag manager. Self-hosted on your infrastructure. Your data never leaves your server.
