TestSprite

TestSprite is a Seattle startup building an autonomous testing agent for the AI-native development era. It plugs into IDEs like Cursor, Windsurf, and VS Code via an MCP server, letting developers trigger full test runs with natural-language commands such as "test my payment features." The agent generates front-end and back-end test cases, executes them in managed cloud environments, and feeds failure analysis back to the coding agent so fixes land in the same workflow. It raised a $6.7M seed round in October 2025 (total ~$8.1M, led by Trilogy Equity Partners) and reported growing from 6,000 to 35,000 users in three months after launching TestSprite 2.0.

The honest picture: TestSprite is young and its core thesis — testing as the bottleneck of AI coding — is still being proven at enterprise scale. Generated tests need review like any AI output, and teams with heavy custom infrastructure may find the cloud-execution model a poor fit. Pricing beyond the seed-stage free tier is not yet fully public, so cost at scale is an open question.

Sign up at testsprite.com, generate an API key from the web portal, and install the MCP server in your IDE (Cursor, Windsurf, or VS Code). Prompt it in natural language to start a test run.
