Extend your app
Let customers add the features and workflows they need to the product they already use.
Let users build the features they want with AI.
TailorKit lets users, AI, and partners build extensions inside your SaaS. Those extensions run in a sandbox and use the components, data, and actions you choose to expose.
Partner integrations
Give third parties a supported way to build and publish integrations for your platform.
Build features with AI
Turn a plain-language idea into a working extension built from your product primitives.
Native product UI
Render extensions with your components so every new feature looks and feels built in.
Open source
Adopt, inspect, and extend an AGPL-licensed framework without betting on a black box.
Sandboxed runtime
Run third-party and AI-generated code safely, away from your core application runtime.
Framework agnostic
Use a framework-neutral extension protocol, with an official React adapter available today.
Managed infrastructure
Deploy extensions through our CDN today, with per-app backend services on the roadmap.
