Why It Has Market Pull

ECC ("Everything Claude Code") is a real, fast-moving open-source agent harness with verified massive GitHub growth, its own product site, a GitHub App, and npm packages — genuine builder momentum, not a one-off viral post, though it remains a solo-founder open-source project rather than a funded company.

  • 234,685 GitHub stars and 35,767 forks verified live via the GitHub API (repo created January 2026)
  • Actively maintained — last push the day before this review
  • Grew out of winning an Anthropic-affiliated hackathon; the founder's recap thread reportedly drew ~900,000 views
  • Independent coverage beyond the project's own channels across multiple tech and business outlets
  • Ships as more than a README: 260+ skills, 60+ agents, an npm package, a security-scanning companion, and a GitHub App

With Adomate you create ads from data, at scale. Take data from your Meta ad account, the ad library and reviews from Trustpilot and Amazon. Build creative research workflows that create branded ad concepts, the way you want. Fully traceable to their original data trigger, no blackbox.

Turn any conversation with your AI Analyst into a polished report, slide deck, or interactive document built from your live data. Generate it from a single prompt, then share it via public link or download as a PDF.

Opus 5 is a step change improvement for the Opus tier powering long-running agents while delivering improvements in coding and professional work.

Research has no natural finish line. An agent can spend ten minutes or ten hours on the same question, and both answers can look finished. Webhound lets you choose how much work the question deserves. Give it a question and a dollar budget. It follows leads and checks weak claims until the budget is consumed, then returns a cited report or sourced dataset with the sources and working documents behind it. Run Webhound yourself or call it from your agent through MCP or the API.

Your website starts decaying the day it ships. Broken links, stale pages, slipping rankings, invisible to ChatGPT. Robynn connects to your live site — no rebuild, no migration. It audits every page against your brand, ICP, and competitors, then proposes evidence-backed fixes. Point at any element, describe a change in plain English. Agents stage it, you approve, Robynn publishes and measures what moved in GA. Wins get reinforced. Regressions roll back. First audit is free.

I’ve been building Echo ( https://echo.tracerml.ai/ ), an experiment in making one AI system out of a pool of open-weight models rather than choosing a single model and using it for every task. It started with a simple experiment. I took a group of models, including GLM-5.2, Kimi K2.7 and others, and ran them on the same evaluations. Then I measured what would happen if, for each problem, you somehow knew in advance which models would be useful and how their outputs should be combined. That hypo... (484 points, 227 comments).

To my knowledge, this is the first formally verified implementation of a 3D constructive solid geometry (CSG) operation: mesh intersection, implemented in Lean 4 and verified against a concise specification that pins down the surface of the resulting mesh exactly and guarantees practical well-formedness conditions on the triangulation. This project is also an experiment in avoiding having to trust AI-generated code. A human reviewer only needs to read 93 lines of formal specification and run the... (89 points, 39 comments).

Hi HN, we built world-model-optimizer, an open source tool to continually improve models specialized to agents. Agent traces you already capture are opportunities to get signal on how to make your model cheaper, faster, better. We do this by continuously a) distilling relevant chain of thought from larger open source models into smaller ones, b) model routing to frontier + OS models, and c) token compaction to remove noise and save on tokens. `wmo build` allows you to build a simulation to optim...

Hey HN! This is Yannick from Tines, really excited to share what we’re launching today. Tines 3B is a new product we’ve built for teams building agents, apps, and automations with AI, on top of the assumption that people are already doing this, whether or not IT or security knows about it. Finance, marketing, and more are building dashboards in Claude Code or Codex. None of it is malicious, people are doing exactly what they were asked to do. The issue is there's no easy way for that work to run... (22 points, 2 comments).

https://seaticket.ai/ After maintaining Seafile, open-source file-sync software, since 2012. Somewhere across those fourteen years, "go check if someone already reported this" turned into one of the most common lines in our team chat. Because the same bug tended to show up multiple times. Nothing connected Github and Discord Issues until my team happened to remember seeing "that thing" somewhere else. SeaTicket is what we built to fix that for ourselves before opening it up. It connects GitHub I... (7 points, 2 comments).

Hey, we built an open-source CLI in Go purposed to help you answer security questions across your cloud, code and runtime. It connects to your GitHub, GitLab, AWS, GCP, Azure & K8s using the credentials that are already in your shell, while limiting itself to read-only. The core innovation here is the trust boundary - our agent has a built-in code execution sandbox with no host or network access; it is exposed to an internal tool which we call an “action gate” that performs read-only HTTP reques...
