Melty

Melty is an open-source, chat-first AI code editor designed for agentic coding workflows, backed by Y Combinator and having completed a Pre-Seed funding round. As an open-source project available on GitHub, the core editor is free to use, with active development visible in its public repositories, though comprehensive commercial pricing tier details beyond the open-source offering aren't clearly documented in third-party coverage.

Its chat-first design philosophy is a genuinely distinct approach compared to traditional code editors with AI features bolted on: rather than treating AI as a secondary autocomplete feature, Melty is built around conversational interaction as the primary way developers write and understand code, aiming for what the project describes as "tenfold efficiency" for engineers.

It's aimed at developers wanting an open-source, chat-first coding editor built specifically around agentic AI workflows, with its early-stage, Y Combinator-backed status meaning the project is still actively evolving — interested developers should check Melty's GitHub repository directly for the most current build and any commercial offering details.
