  • The post argues for a practical open-source “agent stack” in 2026, emphasizing systems that users can self-host and run reliably without hype.

been running this setup for a few months and wanted to share what actually works vs whats just github stars

hermes agent (24k stars, MIT) - runs on your own machine or vps, connects to telegram/discord/whatsapp, persistent memory stored locally in sqlite. your data doesnt leave your network. pair it with ollama and local models for fully offline operation. the memory layer is what separates it from everything else.. your agent on day 30 actually knows your projects and preferences

everything claude code (128k stars) - 27 agents, 64 skills, 33 commands. installs directly into claude code or hermes as a skill set. covers planning, code review, security audits, TDD, token optimization

dify (130k stars) - self hostable visual workflow builder. raised $30M. production ready, not a toy. runs on your own hardware via docker

onyx (17k stars) - self hosted private search across your google drive, notion, confluence, slack. nothing leaves your servers

repomix (21k stars) - one command to pack your entire codebase into a single file claude can read. solves the context problem instantly

flowise (30k stars) - lighter weight alternative to dify if you want drag and drop agent building without the complexity

the combo that works best for me: hermes for persistent memory and 24/7 task handling, repomix for giving it full codebase context, everything claude code for the skill library

all MIT or Apache licensed, all self hostable, all actively maintained
