About Lark
Lark is a modern billing platform with the flexibility to support any pricing model (flat-fee, credit-based, usage-based, hybrid, dimensional, outcome-based, etc.) at any scale.
Whether you're building an AI powered API service or a B2B SaaS product, Lark provides the tools you need to implement complex billing logic without the hassle. Jack and Vijit previously built a usage-based billing system for a large billing provider.
What Lark does
Lark is an automated testing platform that writes and runs end-to-end tests for your product. It is built for developers and teams using coding agents like Claude Code, Cursor, and Codex. Tests are written in natural language, so they are easy to create and maintain. Lark adapts to changes in your UI or APIs, alerting you instead of breaking. It covers frontend, backend APIs, SDKs, and async workflows, with reproducible logs and screenshots. Pricing is not listed on the site.
