About ToggleTown

ToggleTown is a feature flag and experimentation platform aimed at growth and product engineers who lack a dedicated platform team. You create a flag in the dashboard, set its type, default value and targeting rules, install an SDK and toggle the feature on or off instantly without deploying. Rollouts can target specific users, teams or a percentage of traffic.

Other capabilities include separate dev, staging and production environments, audit logs that record who changed what and when, and built-in A/B testing that tracks conversions and reports statistical significance. SDKs are available for JavaScript, React, Node.js, Python and Go, and an MCP server lets AI assistants such as Claude manage flags.

It is a hosted commercial service with a free tier, no credit card required to start, and a pricing page for paid plans. The site publishes comparison pages that set it against LaunchDarkly and Flagsmith, and it notes that no infrastructure needs to be run.
