Show HN: Horizons – OSS agent execution engine

4 months ago

I'm Josh, founder of Synth. We've been working on coding agent optimization with method like GEPA and MIPRO (the latter of which, I helped to originally develop), agent evaluation via methods like RLMs, and large scale deployment for training and inference. We've also worked on patterns for memory, processing live context, and managing agent actions, combining it all in a single stack called Horizons. With the release of OpenAI's Frontier and the consumer excitement around OpenClaw, we think the timing is right to release a v0.

It integrates with our sdk for evaluation and optimization but also comes batteries-included with self-hosted implementations. We think Horizons will make building agent-based products a lot easier and help builders focus on their proprietary data, context, and algorithms

Some notes:

- you can configure claude code, codex, opencode to run in the engine. on-demand or on a cron

- we're striving to make it simple to integrate with existing backends via a 2-way event driven interface, but I'm 99.9% sure it'll change as there are a ton of unknown unknowns

- support for mcp, and we are building with authentication (rbac) in mind, although it's a long-journey

- all self-host able via docker

A very simplistic way to think about it - an OSS take on Frontier, or maybe OpenClaw for prod
