Recurse by Synnada

Recurse is a serverless harness for building and running specialist AI agents, from Synnada, shown by its makers on 25 September 2026. A developer tells their coding agent what the task is and how success will be measured; the coding agent then uses Recurse to generate, run and compare variants of an agent — a system prompt plus Python functions as tools, pinned in a manifest with input and output schemas — until one meets the bar. The chosen agent is deployed as a tool, an MCP server or a bot, and every successful run returns output that matches the declared schema. The makers say they built it for their own client work on agents with a fixed request and response, especially in domains where a result can be checked; their blog carries case studies from August 2026 on game level design. Pricing on its own page is pay per request with no subscription: model calls are charged at the model providers’ token rates, currently with no markup, and serverless execution costs $0.013 a minute; new accounts start with $5 of credit. The site footer names Synnada Inc, while the linked terms name Synnada Labs. A buyer should ask which model providers receive the data and where runs execute. It is listed as “Recurse by Synnada” because the name is shared with unrelated organisations, including the Recurse Center.

Not yet independently verified: The launch date rests on the makers’ own launch post of 25 September 2026.
