Finding a good domain is half the battle. tldx is a blazing-fast, concurrent CLI tool that generates and checks domain availability in bulk via RDAP. Mix keywords, prefixes/suffixes, or regex, and stream results to stdout, JSON, or CSV. Plus, tldx includes an MCP server, empowering AI agents (like Claude) to brainstorm and verify domains for you automatically! Install via Homebrew (brew install tldx). Say goodbye to rate-limits and legacy whois parsing. 100% Free & Open Source in Go.
Pi is a minimal terminal coding harness. Adapt Pi to your workflows, not the other way around. Customize Pi with extensions, skills, prompt templates, and themes. Bundle them as Pi packages and share via npm or git. Pi ships with powerful defaults but skips features like sub-agents and plan mode. Ask Pi to build what you want, or install a package that does it your way.
ModelHub is a native macOS menu bar app for developers working with local LLMs. It helps you discover models from Hugging Face, download the right local build, manage your model library, and use Hugging Face models with Ollama, MLX, LM Studio, llama.cpp, and the tools you already have without bouncing between browser tabs, terminal commands, model cards, and local folders. Ollama, MLX, and LM Studio are great tools. ModelHub is the missing discovery and management layer around them.
Cohere’s fastest and most powerful language model yet: an open-source model for running high-performance enterprise agents with maximum efficiency.
Connect DecisionBox to your Databricks workspace. The agent writes its own SQL, validates every finding against your data, and ships a ranked backlog — no prompting. Read-only, Unity Catalog–scoped. Works with Serverless, Pro, or Classic SQL warehouses. Open source, AGPL v3.
Local Area Network discovery tool with an interactive Terminal User Interface (TUI) written in Go. Discover, explore, and understand your LAN in an intuitive way. Knock Knock.. who's there? 🚪
Mobile devs waste hours building branches locally just to test a PR. Tophat pulls any CI artifact and installs it on simulators or physical devices. For iOS and Android engineers.
Git for your AI agent’s actions. Undo, trace, and control every step. re_gent shows what your coding agent changed, which prompt caused it, and lets you roll back agent work across files and sessions.
Emdash is an open-source desktop app for running multiple coding agents in parallel; one place to monitor sessions, review diffs, and turn issues into PRs.

A desktop interface for the coding-agent CLIs you already use — Codex, Claude Code, Cursor, Gemini, Kimi, and a hosted Shiori provider. Run long-running sessions with project-aware threads, stream agent activity into a readable timeline, and review generated diffs without leaving the app. Source-available, built for work that doesn't fit in one prompt.
LearnHouse is an open-source learning platform to teach your users everything about your product. Built for builders who ship great things but need their users to actually understand them. v1.0 is our first stable release - packed with AI, code execution, discussions, analytics, and everything you'd expect from modern developer tooling. Self-host it or use our cloud. Either way, your content, your data, your community.
Agentspan is an open-source server and SDK for running AI agents as durable workflows. You can define agents programmatically, execute them server-side, and inspect each run and execution state in the UI. Agentspan adds crash recovery, human-in-the-loop approvals, guardrails, tool history, and observability around the agent frameworks and LLMs you already use. MIT licensed.
A unified storage SDK for object and blob backends. One small, honest API. Web-standards I/O. An escape hatch when you need the native client.

You can now give Hermes, Claude Code, and Codex infinite memory. Agentmemory is trending on GitHub with 5,000+ Stars. CLAUDE md dumps 22,000+ tokens into context at 240 observations agentmemory: 1,900 tokens. same observations. 92% less. At 1,000 observations, 80% of your built-in memories become invisible. agentmemory keeps 100% searchable. benchmarked on 240 real coding sessions → Up to 95% fewer tokens per session → 200x more tool calls before hitting context limits → 100% open source
The very first software that uses Claude Code as its operating system, building itself around you as you work, and reinventing how IT runs.
Cline SDK is an open-source TypeScript agent runtime with plugin architecture, native subagents, MCP support, checkpointing, cron jobs, and web fetch. For developers building custom coding agents or CLI tools.
TrustClaw is a personal AI agent that you can self-host on Vercel with one command. Powered by Composio, it connects to 1000+ apps over OAuth, runs scheduled jobs on its own, and talks to you on the web or Telegram. It is fully open-sourced, MIT-licensed and ready for you to take over.
90% of people who try AI agents give up. Three reasons: memory that resets every session, your data sitting in someone else's cloud and a terminal just to get started. Real blockers. OpenHuman fixes all of it. Local-first, privacy-first. It remembers everything about you and actually gets smarter the more you use it. Every feature lives in one simple interface. Fully open source. One-click setup. P.S. The product is in beta, so expect bugs, but we're building and shipping fast.
A Game Boy in your editor sidebar that wakes up while your AI agent works and tucks away when it stops.
