Open source email app being built as a free Superhuman alternative

A developer is building a free, open source alternative to Superhuman, a popular paid email productivity app. Anyone can view the code or set it up themselves.

Superhuman is a paid email app known for fast keyboard shortcuts and AI-powered features, but it requires a monthly subscription. This project aims to offer similar productivity features at no cost.

Because it's open source, anyone can inspect the code, host it themselves, or contribute improvements. The project appears to be in early development. It's not directly related to AI agent building or token cost reduction, but solo builders or developers who want a smarter email workflow without a subscription fee may find it worth watching.

Key points

  • Aims to replicate Superhuman's productivity features as a free, open source tool
  • Anyone can view or modify the code freely
  • Still in early development — functionality may be limited
  • Useful for those who want advanced email features without a monthly fee
