Flat plans plus your own AI keys, instead of ACU, credit or effort metering.
Coding, CRM, projects and memory in one agent OS — not five subscriptions, with a browser, channels and voice built in.
AGPL-3.0 and BYOK. Self-host the same system whenever you want.
Most AI agents bill by usage — ACUs, credits or effort — and bundle the model cost, so the bill is hard to predict. InfiniBot Cloud is a flat monthly plan and you bring your own AI keys. It also covers the widest scope in one system: coding terminals, CRM, projects and memory, a real browser, Telegram and WhatsApp, and voice.
Yes. InfiniBot is open-core under AGPL-3.0 and free to self-host. Of the tools compared here, Hermes Agent and OpenHands are also open source (MIT).
Devin has a much bigger brand, and Devin and OpenHands go deeper on fully autonomous software engineering. InfiniBot's advantage is breadth, predictable flat pricing and BYOK.
Flat from $19 a month with your own AI keys.
