Featureflip Reviews & Product Details

Featureflip is a feature flag, targeting, and experimentation platform from Canopy Labs LLC. It lets engineering teams decouple deployment from release: ship code behind a flag, turn it on for a percentage of users or a segment, and turn it off instantly if something breaks. What happens after the rollout is what most teams carry forever. Featureflip detects dead flags from each flag's evaluation traffic, then a GitHub Action opens one reviewable pull request per flag and deletes the code path across thirteen languages. The rewrite works on the syntax tree with no LLM, so the same input always produces the same diff, and it refuses what it cannot do safely. Merging it can archive the flag it removed. The platform covers percentage rollouts, condition-group targeting, environment isolation, prerequisites, and audit history, with a real-time evaluation API built for low latency. Thirteen SDKs span server-side (Node.js, Python, C#, Java, Go, PHP, Ruby) and client-side (browser JavaScript, React, Swift, Flutter, Android), with live updates over Server-Sent Events. Flags are manageable as code as well as from the dashboard: a Management API on every plan, free tier included, a Terraform provider on the Registry, an MCP server for AI agents, and OpenFeature providers for Node.js, .NET, Python, Go, Java. Pricing is flat and team-based, with nothing metered: no per-seat charge, no active-user count, no evaluation caps, no overage. Solo is free forever.
