Rust

Native desktop automation CLI for AI agents. It controls apps through OS accessibility trees and returns structured JSON with deterministic element references, with extra FFI bindings for embedding in other languages.

Open-source DynamoDB-compatible API adapter with pluggable storage, built for local development, CI, self-hosted deployments, and air-gapped environments.

Runtime safety net for LLM agents that detects runaway token growth, classifies failure patterns, and suggests fixes without extra LLM calls. The project includes a Rust core, Python SDK, examples, benchmarks, and benchmark claims across multiple models and runs.

SpadeBox is an open-source sandboxed tools and JavaScript runtime for AI agents, with Rust core plus JavaScript and Python bindings. It provides file, network, and code-execution tools, supports MCP, and includes examples for JavaScript, Rust, and Python.

Lowfat is a lightweight CLI tool that filters noisy command output before it reaches an AI agent, with plugins, shell integration, and usage stats for token savings.

Local-first AI memory layer for LLM apps with persistent knowledge graph storage, entity extraction, semantic retrieval, and API endpoints for ingesting and retrieving context.

Open-source, local-first desktop workbench for coding agents. It centralizes tasks, sessions, transcripts, artifacts, diffs, containers, and merge-queue state for agents like Claude Code, Codex, and Cursor.

Open-source terminal coding agent in Rust with LLM-native code understanding, shell safety, multi-provider support, and automatic failover.

A local Rust API gateway that lets tools like Claude Code and OpenAI/Anthropic SDKs talk to OAuth-backed providers through OpenAI- and Anthropic-compatible endpoints.

Desktop AI agent for Excel that works on workbook edits with parallel workflows, reversible changes, and local-first file handling. It supports Claude or OpenAI subscriptions, shows proposed edits for review, and preserves workbook structure like formulas, formatting, charts, and named ranges.

Open-source infrastructure for running and automating sandboxed coding agents, with local Docker setup, integrations, snapshots, sessions, and automations.

A Rust-based hybrid local code search tool for developers and AI agents, with BM25 + semantic retrieval, persistent indexing, tree-sitter symbol search, and MCP/gRPC integrations.

Patchwork is a Rust CLI for AST-native code refactoring without LLMs. It can find, replace, delete, and insert code by structure instead of regex, with support for Java, Python, JavaScript, TypeScript, and TSX.

Rust-based PostgreSQL MCP server with 135 tools for Claude Desktop and other MCP-compatible AI tools. Supports stdio, TCP, and HTTP/2 transports, plus quick-start install and setup instructions.

ctx is a local-first desktop workbench for coding agents, now open source under GPL-3.0. The page explains that it runs agents in a desktop environment with worktrees, transcripts, artifacts, diff review, container boundaries, and a local merge queue.

A Rust-based checker that compares a changed function against its prior version on deterministically generated inputs and reports counterexamples when behavior changes. It includes a PR gate via GitHub Actions, CLI usage, signed receipts, and docs for release/signing.

An open-source infinite-canvas workspace for coding with AI agents. It turns a codebase into a source-backed visual map for architecture review, refactors, PR walkthroughs, and guided code exploration.

Darc is a CLI tool for coding agents that indexes prior agent sessions for grep-like memory search and lets teams share encrypted session indexes through Git-backed branches.

A native macOS Markdown viewer that renders GitHub-flavored and Obsidian-style Markdown in a lightweight app with CLI, drag-and-drop, file association, math, Mermaid diagrams, and frontmatter support.

Fabrica is a Rust-based terminal coding agent with a full TUI, multi-provider model support, and built-in file and shell tools for autonomous coding tasks. It also supports ACP server mode for programmatic control by compatible clients.

Local-first encrypted memory engine for AI agents, built in Rust with MCP support and persistent cross-session memory for Claude and other MCP clients.

An associative memory database that stores facts in plain language and recalls them by meaning. It ships as a Rust core with optional SQLite, encryption, and HTTP server features, plus examples and API docs.

Local-first agentic coding assistant in Rust with a terminal UI, embedded web UI, phone app, always-on gateway, and LAN grid dispatch across multiple machines.

A local AI IDE plugin that cleans up messy prompts before they reach Claude, Cursor, or OpenCode. It fixes typos, dropped words, and split tokens on-device with no network or token cost.
