Developer Tools AI Tools

Open-source runtime guardrails for AI agents with cost limits, loop detection, policy enforcement, observability, and dashboard/CLI support.

A browser automation CLI built for AI agents, with compact text snapshots, ref-based element selection, and built-in support for navigation, screenshots, network, debugging, and session state.

A remote MCP server that lets AI agents manage podcast pods by conversation. It supports token-based access and can create, edit, combine, and generate episodes through clients like Claude Code and other MCP tools.

Open-source project showing how to run a 28.9M-parameter language model on an ESP32-S3 microcontroller, with on-device inference, firmware, wiring, training code, and measured results.

Mission control for AI coding agents, letting users run, watch, resume, and orchestrate tools like Claude Code, Codex, Copilot, and opencode from one terminal and live dashboard.

A provenance-aware memory layer for AI agents that stores user facts, interaction history, and third-party claims with source tracking and quarantine rules.

Telemetry is an observability platform for AI and LLM apps that tracks model calls, tool steps, retrievals, tokens, cost, latency, and errors. It supports OpenTelemetry ingest, TypeScript and Python SDKs, and integrations like Vercel AI SDK and LangChain.

Headroom is an open-source context compression layer for AI agents. It compresses tool outputs, logs, files, RAG chunks, and conversation history before they reach the LLM, with support for a library, proxy, and MCP server.

ReactBench is a benchmark for evaluating coding agents on realistic React work, with published scores, cost comparisons, and example tasks focused on production-grade frontend issues.

An open-source Python tool that controls AI agent loops using real-time convergence signals instead of a fixed max-iterations cap, with rollback and adapters for popular agent frameworks.

Looma is a local-first Python CLI that turns coding-agent history into resumable project context. It reconstructs work items, decisions, blockers, linked commits, and next steps from Claude Code, Codex, and Cursor sessions, with optional local LLM extraction and no cloud or API keys.

Pylon is a full-stack TypeScript framework built for coding agents, combining schema, policies, live queries, auth, storage, jobs, and deploy in one runtime. The page shows a clear product, docs and CLI entry points, open-source positioning, and concrete examples of how agents can scaffold, inspect, and ship apps.

A local-first tool that mines reusable skills from coding agent transcripts and turns approved patterns into SKILL.md files for future sessions.

Dex is an agent-native analytics engineering toolkit for working with warehouses and dbt projects. It supports exploration, dbt transformation, semantic modeling, and schema-drift maintenance, with installs for Claude Code and other agents.

Mirrors turns production traces into an isolated, runnable copy of an AI agent’s environment so teams can replay workflows, reproduce bugs, and test changes safely before shipping.

Open-source sandboxing and secure file system for agent code execution, with built-in job queues, execution history, retries, Docker isolation, and optional gVisor hardening.

Local-first desktop LLM wiki that hydrates notes, PDFs, emails, and docs into Markdown entries, then retrieves them with keyword search and link traversal instead of embeddings or a vector DB.

A gated publishing engine for agent-generated HTML and Markdown. It gives teams a permanent, authenticated URL for artifacts produced by agents, with support for CLI, MCP, browser, comments, versioning, and company SSO.

An open-source mixture-of-agents server that fans prompts out to multiple LLMs, judges the responses, and synthesizes a final answer. It exposes an OpenAI-compatible API and also includes an agentic coding harness plus integrations for tools like Claude Code, aider, Continue, LangChain, and Pi.

ZeroFS turns S3-compatible buckets into a primary storage layer with POSIX access over NFS and 9P, or raw block devices over NBD. It includes encryption, compression, caching, checkpoints, read replicas, and a web UI, with public CI and recorded demos backing the project.

A Dockerized home-internet latency monitor that tracks ping, traceroute, jitter, packet loss, and WAN load, then adds AI-written root-cause notes on a Grafana dashboard.

guestlist is a Python library and HTTP API that rates websites green/yellow/orange/red based on how likely AI and computer-use agents are to get through. It helps teams avoid failed crawls and browser automation retries by checking access before spending requests.

Cloud cost awareness for AI coding agents and IDEs, with real-time pricing for IaC changes, cost tradeoff suggestions, tagging fixes, and policy-aware guardrails.

crune is a static web dashboard and CLI for analyzing Claude Code session logs. It offers session playback, analytics, semantic knowledge graph generation, and reusable skill synthesis from prior sessions.
