Flagsmith gives software engineering teams a self-hosted or fully managed feature flagging platform for controlling releases across web, mobile, and backend systems. Ship code behind a flag, then decide who sees it — by environment, user, or custom segment — without redeploying.
Run Flagsmith however fits your infrastructure: our managed cloud, your own private cloud, or fully on-premise.
What you get:
Progressive rollouts with one-click rollback if something breaks
Live config changes — flip features on or off instantly, no redeploy required
Segment-based A/B and multivariate testing
Project and role-based access control for multi-team organizations
Native integrations with the tools already in your stack
MCP support and a CLI so AI agents and scripts can manage flags directly
Open source at its core, Flagsmith is built for teams that want control over where their configuration data lives.

Engineering teams shipping with AI have a new bottleneck: validation. Code output has accelerated. Quality hasn't. Checksum closes the gap.
Checksum is a continuous quality platform with a suite of AI agents that handle testing end-to-end, at every stage of the development lifecycle. Where most tools wait for a human to trigger them, Checksum runs autonomously in the background, generating tests, executing them, and repairing failures without manual intervention. Seventy percent of test failures are resolved automatically through real-time auto-recovery.
The platform covers every layer: end-to-end UI flows via Playwright, API endpoint chains, and targeted CI tests scoped to exactly what changed in a PR. All tests land as real code in your repository and are delivered as standard Playwright, owned by your team.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents. Type /checksum and your coding agent's output gets tested before it ever reaches review. Generation and healing happen on Checksum's cloud infrastructure which means no LLM tokens consumed, no local resources required.
The result: test suites that stay green as the product evolves, fewer regressions reaching production, and release confidence that scales alongside AI output.
