Products that do what Lunar, a coding harness extensible with Lua does
Hi all! Sharing a small pet project my agents and I have been working on: Lunar, a coding harness configurable and extensible via Lua scripts. I'm already using Lunar to develop Lunar :) Give it a try! Soon you will be able to extend it using Lua hooks.

LunaRoute is a high-performance local proxy for AI coding assistants like Claude Code, OpenAI Codex CLI, and OpenCode. Get complete visibility into every LLM interaction with zero-overhead passthrough, comprehensive session recording, and powerful debugging capabilities. - See Everything Your AI Does - get full logs (JSONL), summary of sessions including tokens used (input/output) as well as tools usage and success rates. - Privacy & Compliance Built-In - redact or tokenize any sensitive information (regex based). - Speaks OpenAI and Anthropic dialects so you can route (and translate)…

I'm releasing Lunar, a new Lua 5.1 compiler and virtual machine written entirely in Go. It includes the standard libraries, coroutines as well as supporting Lua 5.2-style goto. The embedding API avoids the Lua C API’s stack-based interface in favor of typed Go values and callback frames. Libraries and script-file access are opt-in, so the host explicitly controls what Lua code can access. On my current benchmarks and use-cases, Lunar is often ~1.5x to 2x faster than GopherLua and Shopify’s go-lua. Its largest improvement however is memory use: loading a 9 MB CBOR-derived object graph…

Hi HN. I'm the founder of Phoenix Labs (ex TikTok, Applied AI) and we're open sourcing our internal tooling today which is like a toolchain / meta-harness for CLI agents useful for really scaling eng and creative work. We are a very small team who's building a very ambitious product so we had to find ways to squeeze every ounce of efficiency that we could get our hands on. Harness strengths of different models (Claude, GPTs) and CLI-harnesses (Claude Code, Codex), safe/robust browser integration to speed up UX/QA testing, teams cli to speed up security reviews and parallelize…

I built LunarBasic because I wanted a modern recreation of BlitzBasic from back in the day. I wanted it to have good step debugging features, and I wanted it to compile down to a native binary with no external dependencies. I do know there's an open source BlitzBasic out there but I wanted something simpler and more concise. It does have a "pro" feature set, but for the foreseeable future, anyone joining up will have the pro version in perpetuity (eg I'm not trying to sell anything here). It's early (v0.8.0). Would love feedback on the language design and compiler output, especially from…

Hi HN, I built VAEN (an open source CLI) because I kept running into a boring problem with AI coding-agent workflows: the setup becomes useful, but then it is hard to move. A good, useful agentic harness consists of more than just instructions: skills, mcp servers and more. There should be a better way to share those than just .MD files, and that is why I created VAEN. What works: create a yaml, run the CLI commands as per the repo, and get a .agent file that you can share and extract. Think of how awesome it could be if anyone could use a very useful agentic harness, and share it with one…

Hi HN. This is a script I have been using for some time for coding tasks, which I have polished a bit and published. The motivation behind this script was to have an agent with persistent session which I can use from the shell like a regular command. It _can_ also be scripted, although I don't use it in such a way. The script uses a minimal prompt, which just tells it to use standard unix tools to do everything. I was surprised at how well it worked, when using a good model. Qwen3-coder is on openrouter, and it works well with the minimal instructions. I also tested qwen2.5-coder with ollama…

I built Hydra because I kept losing my flow when Claude Code hit usage limits mid-task. I would copy context, open another tool, and then re-explain everything. This would be super annoying for me. Hydra wraps your AI coding CLIs (Claude Code, Codex, OpenCode, Pi, or any terminal-based tool) in a single command. It monitors terminal output for rate limit patterns, and when one provider runs out, you switch to another with one keypress. Your conversation history, git diff, and recent commits are automatically copied to your clipboard so you can paste and keep going. The fallback chain is…

This is a little side project I've been working on for the last few months. It's a service hosting Lua scripts behind static HTTP endpoints in a fully sandboxed environment. It's something I've built to scratch my own itch and now I'm launching a free public beta to see if it's something that anyone else also finds useful. My first professional job was for a company building an industrial IoT platform who's most unique feature was their Lua-based scripting platform. I ended up loving Lua so much that at my next job, at SmartThings, I ended up being the main instigator who made the Lua-based…

Hey HN. I built an AI agent harness over the past few months and I'm open sourcing it today. Some context on why. I've been building with Claude Code daily using this harness. It orchestrates multiple AI agents as a team, with a dashboard, chat, kanban board, the works. I used it to build a full SaaS product (MyUpMonitor, https://myupmonitor.com) in about 24 hours of focused coding. Then yesterday Anthropic announced Mythos and decided to keep it behind closed doors. Meanwhile I'm paying for Claude and I can't access their best model. I don't think that is nice at all... So I'm…
