DevKit
DevKit is a browser-based developer assistant that combines access to multiple large language models with more than 30 built-in mini-tools. You get API testing, database queries, code generation, editors, and utilities in one workspace instead of juggling separate apps and browser tabs.
The chat layer is tuned for developer workflows rather than general conversation. DevKit supports models including GPT-4o, Gemini with large context windows, and Llama via Groq, so you can pick the right model for speed or depth. Mini-tools cover public API config generation, plain-English Postgres queries with result plotting, in-chat code generation and execution across many languages, and creative coding with p5.js.
The product is aimed at software engineers, founders, and backend developers who want faster API testing, SQL work, snippet editing, and day-to-day utilities without leaving the browser. DevKit reports use by teams at companies including Amazon, Microsoft, Uber, Skyscanner, and Resend.
