I compared all six published AI agent platforms in our catalogue on the data we hold for each: entry price, whether a real free tier exists, the no-code builder, the breadth of prebuilt integrations, multi-agent support, and whether you can self-host. I weighted the scoring for a lean B2B founder specifically, someone with no engineering team, a tight budget, and a need for agents that take work off their plate rather than answer one-off questions. Pricing and feature data reflect our catalogue as of June 2026; usage-based plans were judged on their entry tier and how predictably they scale, since unpredictable credit billing punishes a small team hardest.
