Hey Product Hunt! 👋
I'm the maker of Quark Agent. I built it because I kept hitting the same wall: every agent framework I used started small, then swallowed my whole codebase. I wanted the opposite — a kernel so small you can read it in one sitting, where everything (tools, channels, models, protocols) is just a plugin.
So the core is 5KB: Agent + Provider + Memory + Sandbox. On top of that:
• 16 tools you compose with a single defineAction
• 7 channels out of the box — the same agent runs in your terminal, Slack, Discord, Feishu, Telegram, GitHub webhooks, or as an HTTP API
• MoA routing so cheap models handle easy tasks and strong models handle hard ones
• A sandbox policy layer so it's safe to let it run shell commands
• GEPA, which lets the agent evolve its own prompts over time
And zero third-party SDK dependencies — every provider talks over native fetch, so the install stays tiny.
It's MIT open source and already at v0.3 with an 89% benchmark pass rate. v0.4–v1.0 will bring npm publish, computer-use / browser-use, multi-agent orchestration, and an MCP marketplace.
I'd genuinely love your feedback — especially from anyone who's felt agent frameworks are too heavy. What would you build on a 5KB kernel?
