We track open source releases so you don’t have to. Here are the seven most useful tools that landed in the developer community this month — all free, all open source, all worth at least 10 minutes of your time.
1. Ghostty 1.1 — The Terminal That Actually Ships Features
Mitchell Hashimoto’s Ghostty terminal emulator hit 1.1 with native GPU rendering improvements and a new split-pane system that doesn’t require a multiplexer. If you’ve been waiting for a terminal that combines Kitty’s performance with Alacritty’s simplicity, this is the release to try.
2. Ollama 0.5 — Local LLMs Just Got Easier
Ollama continues to be the easiest way to run LLMs locally. Version 0.5 adds parallel request handling, which means you can now run multiple concurrent prompts against the same local model — a huge quality-of-life improvement for developers building local AI apps.
3. Mise 2026.3 — The polyglot runtime manager
Mise (formerly rtx) has become the defacto replacement for asdf, nvm, pyenv, and rbenv combined. The March release adds significantly faster shim execution and better integration with direnv for automatic environment switching.
4. Turso libSQL 0.9 — SQLite That Scales
Turso’s libSQL fork of SQLite continues to mature. The 0.9 release adds native vector search (useful for embedding storage in AI apps), making it a compelling option for developers who want SQLite’s simplicity with vector database capabilities built in.
5. uv 0.7 — Python Package Management, Finally Fast
Astral’s uv keeps getting better. Version 0.7 adds workspace support for monorepos and significantly improved lock file resolution. If you haven’t switched from pip/poetry/pipenv yet, this is the release that should convince you.
6. Zed 0.15 — The Collaborative Code Editor
Zed, the Rust-based code editor from the Atom creators, hit 0.15 with improved extension support and a new inline diff view for AI-suggested changes. The performance advantage over Electron-based editors remains its killer feature.
7. Hurl 5.0 — HTTP Testing Without the Boilerplate
Hurl lets you test HTTP endpoints using a simple, human-readable format. Version 5.0 adds GraphQL support and a new –test mode that integrates cleanly into CI pipelines. If you’re currently writing Python scripts or using Postman collections to test APIs, Hurl is worth evaluating.
