Hyperextensible, Lua-powered Vim-based text editor.
The Neovim repository edition is available under Apache-2.0 with documented installation or build instructions and no required source-license subscription. Build/setup work, your device or compute and storage remain your costs. This check covers that source edition; managed services, premium extensions and commercial relicensing, if offered, are not included or price-verified.
Use a full editor with a documented local model connection.
The Personal editor is free. Zed-hosted Pro is USD 10/month with USD 5 included tokens and usage billing beyond that; Business is USD 30/seat/month. Pro has a trial ending after 14 days or exhaustion of its USD 5 trial balance. External models, provider accounts and local hardware have separate costs.
Edit code in a Rust desktop editor with language-server features, optional modal editing and remote-development support.
The Apache-2.0 editor is free to use without an editor subscription. Language servers, remote machines, optional services and plugins have separate setup and terms. Lapce offers local coding features as an alternative to Sublime Text; plugin compatibility and remote-development behavior differ.
Edit local or SSH-session text files in a terminal with familiar shortcuts, split panes and syntax highlighting.
Micro is MIT-licensed software with no required editor subscription. Your computer, terminal and optional SSH host are separate. It can replace local text-editing tasks, but it is not Sublime Text’s graphical interface or an included cloud development service. Third-party plugins and clipboard behavior need their own review.
Full-stack Python platform for web apps and internal tools.
Official pricing offers $0 for one published app with limited AI/hosting and public repositories. Pro starts $25/month with a usage allowance and paid tiers scale that allowance; Apache framework is distinct from managed services.
The provider and official README explicitly commit to CodeEdit being free forever; actual source license is MIT. You provide a compatible Mac and any external developer tools/services. No cloud or model allowance is bundled.
