What is Tessl?
Tessl is ai coding agents from Tessl AI Ltd, based in London, United Kingdom. Spec-driven development platform that checks agent-written code against a team's standards.
AI coding agents go a step beyond autocomplete: you assign a task and the agent plans it, edits multiple files, runs the tests and opens a pull request for review. The good ones are genuinely useful for migrations, test coverage, dependency bumps and well-specified bugs. The review step is not optional — an agent that is confidently wrong across twelve files costs more time than it saves.
A free plan is available, with paid plans for growing teams.
