StateSync Reviews & Product Details

StateSync lowers the cost of AI coding agents and shortens the time they take to finish a task. It is a desktop app for Windows, macOS and Linux that runs the agents a developer or team already pays for, such as Claude Code, Codex, OpenCode, Cursor CLI and GitHub Copilot CLI, on their existing subscriptions and API keys. Most of an agent's bill is the conversation being sent back to the model on every step. StateSync builds a map of the codebase on the developer's own machine and gives the agent faster tools for finding, reading, editing and running code, so each task needs fewer, shorter requests. Usage limits stretch further, and a conversation can be handed to another agent mid-task when one runs out. The app also brings terminals, a change review view and plan usage meters into one window. In our run of the open-source TokenBench harness, 55 real coding tasks with Claude Code cost 46% less and finished 48% faster than the plain agent, with quality the same or slightly better. We ran it ourselves; the harness and tasks are public, and an independent evaluation is pending. Code, prompts and chats stay on the developer's computer. Plans start at $8 a month with a 7 day trial.
