Dev built a personal AI harness to run his SaaS business, with 50+ cron jobs

Reddit user petargeorgievv explains why he stopped relying on existing open-source AI harnesses (OpenClaw, Hermes, t3code) and vibe-coded his own personal system instead, running on a private Tailscale network.
Key points:
- Started from a single Claude prompt combining OpenClaw's Heartbeat, Hermes-style memory, and t3code's multi-account chat UI, built with React/shadcn and memories stored in a GitHub repo
- Grew into website monitoring, GSC keyword tracking, and 50+ cron jobs, with each SaaS project in its own workspace and memory
- Integrates his PostFast MCP for scheduling posts from chat and the API of his email SaaS SendHeron for full automation; a second coding-only harness runs projects on a VPS with code-server, usable from phone or tablet
- Core argument: make the underlying model swappable so the system survives any provider rug pull, and build custom tools for yourself with AI. He doesn't plan to sell it.
