tokentab

tokentab is an open-source AI developer tool for local token and cost reporting for AI coding tools. It is useful when a team needs practical control over model workflows instead of another opaque web app. The project is published on GitHub, ships with a public README, and is designed for builders who are comfortable running code locally or inside their own infrastructure. The README says tokentab reads local session logs from Claude Code, Codex, Gemini CLI, and a Cursor slot that is wired up but not finished. It reports token usage and cost by model, project, day, and activity, offers JSON output, and can run a localhost web dashboard. The main value is that tokentab turns a messy AI workflow into something operators can inspect. Developers, technical leads, and teams using Claude Code, Codex, Cursor, or Gemini CLI can use it to see what happened, repeat a workflow, and make safer decisions before spending more tokens or giving an agent more access. The repository documents the core setup path and keeps the implementation visible, which matters for teams that need to review privacy, deployment, and maintenance tradeoffs before adopting a tool. Setup is aimed at technical users. The README documents cloning the repo, running pip install -e ., and then launching tokentab or tokentab web. That makes tokentab a better fit for engineering teams, AI infrastructure owners, and power users than for nontechnical buyers who expect a hosted account and a sales-led onboarding flow. The upside is control: the tool can run close to the data, follow the repository's documented configuration, and avoid sending extra telemetry to a third-party product unless the operator adds it. For OpenTools readers, the most important question is whether the project solves a real agent or model-operations pain. tokentab does. It sits in the practical layer around LLMs: access, logs, visual work, training recipes, or a desktop workspace. That layer is where many AI teams lose time because the model itself is only one part of the system. A small utility that makes requests traceable, costs visible, screenshots testable, or local sessions easier to manage can save more time than switching models. Pricing is simple because the repository is open source. The GitHub repository is MIT licensed. There may still be infrastructure costs for the models, GPUs, APIs, or machines that a user connects to it, but tokentab itself does not require a listed SaaS subscription. Teams should still review the README, license, release history, and security posture before using it in production. The strongest use case is a builder or platform team that wants a transparent component it can audit, modify, and run with its existing AI stack. The practical takeaway: try tokentab when the workflow described in its README matches a current bottleneck. It is not a general chatbot and it is not a closed managed service. It is a focused developer tool in the Python, local JSON logs, and the Rich terminal library ecosystem that can be evaluated from source, tested locally, and adopted gradually. That makes it a good candidate for pilots where a team wants measurable gains without committing to a new vendor platform.
