Open-source, self-hostable sandbox for AI agents. It lets agents work inside isolated Linux containers through MCP tools, with CLI and host-level admin controls for creating, managing, and exposing boxes.

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

A loadable SQLite extension that adds column-oriented storage and analytics for fast local OLAP-style queries, with benchmark data and build instructions.

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.

OpenWorkers is a thesis-focused research assistant that searches literature, verifies citations, critiques ideas, and produces structured research support without writing the prose for the student.

Semble is a local-first code search tool for agents. It offers natural-language search, an MCP server, bash/AGENTS.md integration, and a Python API, with claims of faster indexing and much lower token usage than grep+read.

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.

Open-source agentic mesh for governing AI agents across enterprise systems, with identity, policy enforcement, audit trails, observability, and Kubernetes-native deployment.

A research article from Applied Compute on how agentic, tool-using workloads differ from traditional LLM benchmarks, with production observations, workload profiles, and an open-source harness for replaying traces.

A CLI for the Slack Web API built for coding agents. It exposes Slack methods through a single command format, supports JSON stdin, dry runs, pagination, and discovery commands, and installs via npm.

Open-source Go tool that routes multiple coding-agent sessions through a single IRC channel so they can collaborate with each other and with the user.

Hyperset is a local-first debugging tool for coding agents that captures runtime evidence from your app and feeds it back into the agent. It supports Node.js, Python, and Go, and can work with its own agent or tools like Claude Code, Codex, and OpenCode.

A data-backed study showing which major websites block specific AI crawlers in robots.txt, with breakdowns by crawler, site type, and a downloadable CSV.

Smelt is an open-source terminal coding agent with a Rust core and Lua plugins, aimed at developers who want a fast, customizable command-line workflow. The page shows install steps, plugin support, vim mode, themes, and benchmark claims comparing memory and speed against other agents.

A local-first Rust PDF toolkit that works as a CLI, MCP server, REST API, WASM browser app, and desktop app for document workflows. It supports PDF merge, split, rotate, compress, OCR, PII scan, signature validation, and other agent-friendly document tasks.

A Rust command-line tool that measures source code, analyzes change impact, and estimates AI, tool, and human delivery costs from local source trees.

Open-source Windows desktop AI assistant for local and cloud models. It supports chat, coding workflows in project folders, web browsing, file access, voice mode, local document retrieval, MCP integrations, and optional OpenAI-compatible/API provider connections.

A developer tool that turns Apple Human Interface Guidelines into deterministic Markdown, with a CLI, MCP server, and packaged agent skill for AI coding workflows.

A transparent SQL wire-protocol proxy that blocks destructive queries before they reach PostgreSQL or MySQL, with no application code changes required.

Kavela is an AI automation platform that turns plain-language instructions into runnable workflows, connects to apps, and adds a reviewer step so runs are checked before results reach the user.

A macOS Markdown editor designed to work smoothly with AI agents editing the same document at the same time. It uses Y.js to merge concurrent changes, preserves Markdown formatting details, and includes a live preview with support for GitHub-flavored Markdown and mermaid diagrams.

Self-hosted project management for agencies and client work, with tickets, time tracking, docs, meetings, and an AI assistant that cites its sources. The repo also exposes an MCP server and REST API for external agents and tools.

An embedded Rust database that speaks SQLite and adds built-in vector and keyword search, plus CLI, shell, and MCP server support for agentic workflows.

A live evidence-based lookup and audit service for MCP servers. It checks public health and ownership signals, returns PASS/REVIEW/BLOCK/UNKNOWN, and offers both REST and MCP access for agents.
