Top Rust GitHub Repositories & Open Source Projects (2026)

Lore is a next-generation, open source version control system

IP addresses break, dial keys instead. A library that adds QUIC + NAT Traversal to your apps.

A Rust toolkit for the Oura Ring (Gen 3/4/5): reverse-engineered BLE protocol, event decoders, and reimplemented data-processing algorithms. Sync, store, and analyze your data locally.

Annotate terminal text, review documents and agent replies in Herdr, and send the feedback straight back to the agent.

agent runtime security - zero trust, zero setup, zero latency.

A beautiful, private, local-first personal finance tracker. Investments, net worth, spending, and simulations.

Open-source, local-first Granola/Otter alternative that Claude Code, Codex, Cursor, and any MCP client can query. Meetings, calls, and voice memos transcribed on-device into markdown you own.

The Fully Customizable Desktop Environment for Windows 10/11.

Community-built comprehensive 2D content creation appplication for graphic design, digital art, and interactive real-time motion graphics powered by a node-based procedural graphics engine

The Native Terminal Emulator with a builtin AI Harness

AI-native Bash shell for Windows: bash syntax, native Windows paths, Unix commands, direct execution of real Windows binaries. No WSL, no emulation - for humans and AI agents.

Pandoc for AI chats. Move ai chats across harnesses: Claude Code, Codex, OpenCode, Cursor, and more. Rust library, CLI, and WASM.

An efficient AI coding agent extendable by neovim-like Lua plugins

underclass: an OpenAI-compatible pooling proxy that pins sessions to one account (prompt cache stays warm), cools quota-exhausted subscriptions until their window resets, and fails fast with the earliest Retry-After when the whole pool is dry.

Open-source desktop AI agent for tools, files, knowledge, workflows, and real deliverables.

LayerFS gives every agent an isolated, disposable filesystem fork without copying the shared base. Useful states become durable, deduplicated checkpoints with workspace-scoped tool history—ready to branch, rewind, or reuse across parallel development, environment experiments, and MCTS-style rollouts.

Extremely fast Query Engine for DataFrames, written in Rust

Apache Iggy: Hyper-Efficient Message Streaming at Laser Speed

mouse & keyboard sharing via LAN

GitComet is fastest open source user interface for GIT workflows
