StellarFirm

StellarFirm builds customizable agentic assistants for your work, runs subagent teams on multi-step projects, and lets you approve every output before it ships.

StellarFirm is a platform for building customizable agentic assistants for your work, rather than choosing from a fixed catalogue of agents. You shape each assistant around the task in front of you, break a project into steps, and run subagent teams with domain skills — and you approve every output before it goes out, so the assistant does the work and you keep final say.

It runs on hosted StellarFirm credits or your own Claude, GPT or OpenRouter key, and Green mode can prefer smaller open-source models to cut token use. The best fit today is complex, multi-step project work — light one-off chat can feel heavy by comparison, and the marketplace for selling agentic teams is not live yet.
