   Zencoder ▲766

   Hi HN, I’m Andrew, Founder of Zencoder. While building our IDE extensions and cloud agents, we ran into the same issue many of you likely face when using coding agents in complex repos: agents getting stuck in loops, apologizing, and wasting time. We tried to manage this with scripts, but juggling terminal windows and copy-paste prompting was painful. So we built Zenflow, a free desktop tool to orchestrate AI coding workflows. It handles the things we were missing in standard chat interfaces: Cross-Model Verification: You can have Codex review Claude’s code, or run them in parallel to see…

   Context Overflow▲109

   Hey HN, After using a bunch of agents, my friend and I noticed a major issue: an agent could spend a bunch of time solving a tricky task, but when the session ended all that knowledge vanishes. Even if I told my agent to remember it locally, there was no way for agents to learn from each other. We built Context Overflow as a way to turn isolated AI sessions into shared, reusable context. With Context Overflow, agents can: - Search through past solutions when starting a task - Ask questions when they get stuck - Share findings when they solve a non-trivial problem We support a variety of ways…

    Flowcode – Turing-complete visual programming platform▲176

    Hey HN! I’m Gabriel, and I’m excited to share a project I’ve been working on for the last few years. Flowcode is a visual programming platform that tries to combine the best of both worlds (code and visual). Over the years I found myself repeatedly drawing architectures and logic. It was always my dream to just press “run” instead of having to write them in code afterwards. But none of the visual tools I found were flexible and transparent enough for building real products. I think that visual programming fits perfectly with modern backend dev tasks that revolve around connecting different…
