Developer Tool AI Tools

WebLLM is a high-performance in-browser LLM inference engine that runs locally in the browser with WebGPU acceleration. It exposes an OpenAI-compatible API, supports streaming and JSON mode, and includes examples for building chat apps and browser extensions.

Self-hosted observability and control plane for production and coding AI agents, with live timelines, fleet-wide feeds, token budgets, MCP allow/block rules, and support for Claude Code plus a Python sensor.

Browser extension that scans pastes for credentials and PII before they reach LLM chat sites, with local on-device inference and no network calls.

Open-source runtime for multi-agent AI systems with job scheduling, DAG orchestration, shared memory, tool execution, and real-time observability.

Linux-only kernel-level audit feed for Claude Code or other matched agent sessions, streaming exec, file, and network activity in real time.

Subarr is an open-source coordination layer for the *arr subtitle stack. It adds subtitle coverage tracking, audio-language verification, provider success tracking, queue management, Whisper tuning, and post-transcription quality checks for Bazarr/Subgen workflows.

A Windows system-tray app that shows Claude Code session and weekly rate-limit usage at a glance, with hover and click views for more detail.

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 authorization engine for AI agents that adds confidence-based gating, human review, policy-as-code, and audit logging. The repo shows quickstart code, local demo steps, SDK installs, and self-hosting options.

Open-source autonomous development pipeline for Claude Code that moves from spec and planning through implementation, validation, PR creation, Codex review, and bug triage.

A Claude Code plugin that lets you stash ideas during a session with /stash commands, then pop them back later without losing context.

Open-source CLI and agent infrastructure for handling paid API requests. It detects 402 payment challenges, signs stablecoin payments with a local wallet, supports MCP, and includes a payment debugger plus catalog tooling.

Amnitex is a local, lossless memory layer for MCP-capable AI coding assistants. It installs as a CLI, exposes tools like search, recall, remember, and list keys, and is designed to work across clients such as Claude Desktop, Cursor, Cline, Continue, and Zed.

A cross-platform agent skills repository for consensus-based R&D and repo automation. It describes a multi-agent loop that generates independent plans, converges through a meta-judge, and supports platforms like Claude Code, Codex, Cursor, and Gemini.

A tiny GPT implementation in pure Go, trained on Jules Verne books, with runnable code and notes that explain the model’s evolution and design choices.

A loopback HTTPS proxy that swaps placeholders for real API keys at request time, keeping secrets out of the agent process. It uses Bitwarden Secrets Manager and supports scoped bindings for hosts, methods, and paths.

AutoGPU is an open-source project for using AI agents to design and harden a GPU-like chip end to end, from Verilog through synthesis and place-and-route to GDSII. The repo shows a concrete fp8 matmul accelerator flow, quick-start steps, and documentation for running the design/hardening process.

An open-source shim that lets Cursor canvas .tsx files render on the web by aliasing cursor/canvas to a Mantine-backed implementation. Includes install steps, runtime setup, supported API coverage, limitations, and a live example deployment.

Open-source local compute fabric for AI agents. It runs a single-node K3s stack through Docker Compose, provisions isolated Ubuntu sandboxes, and exposes native MCP support for local agent workflows.

An experimental RAG lab for constrained environments, with configurable document classification, chunking, retrieval, reranking, and chat context assembly. It includes Open WebUI integration and emphasizes debugging retrieval and context failures.

Kit is a developer workspace that combines an editor, Chromium browser, terminal, email, calendar, whiteboard, and autonomous agent with shared AI context across the whole environment.

Stage CLI is an AI-powered code review tool that groups local changes into logical chapters and helps users review what matters before diving into the code. It works with any AI agent, installs via npm, and can be invoked as a local command to open a browser-based review UI.

A service-boundary-aware coordination layer for heterogeneous LLM code agents via MCP. It combines versioned Markdown documents, pub-sub notifications, diff-aware updates, and a web dashboard for browsing, search, and AI chat.

A GitHub repository that packages Claude Desktop for Linux with install paths for Debian/Ubuntu, Fedora/RHEL, Arch AUR, and NixOS, plus MCP support and system integration features.
