Hacker News, Product Hunt, App Store, Stack Overflow, Lemmy
What users praise

- • OpenAI-compatible chat completions endpoint means agents can be plain HTTP servers in any language
- • YAML-declared agents with natural-language descriptions remove routing code from application services
- • Vendor-neutral, self-hosted option avoids lock-in to managed AI gateways like Portkey or Cloudflare AI Gateway
What frustrates them
- • No verified community feedback in this dataset — every scraped 'Arch' post is about something else
- • Rebrand from Arch to Plano splits discoverability and muddles search results badly
- • Free hosted Plano LLMs are US-central only and described as a first-run experience
- • Scaling production means self-hosting a 4B routing model or negotiating keys on Discord
