Platforms for building your own agents, with no code or with a framework, where the agent decides its own steps: tools, memory, multi-agent setups, deployment and monitoring. Each one will be used to build the same three agents and be tested on the builder, tool connections, testing, deployment, monitoring and what it costs.

Every AI agent builder I follow
Every AI agent builder I follow, in alphabetical order. None has been through my bench yet: each one is queued for the nine tests, and the first reviews appear here as they are finished. The statistics measure 25 of them each month. 24 more listed tools are not measured here: 8 are measured in the category of their main product, 13 sit on shared domains whose traffic is not their own, 2 live on domains whose traffic is mostly another product and 1 has no product traffic of its own yet. Each of those is marked on its card.
