You know what Claude Code costs per seat. But do you know which sessions burned the budget, which model did the work, or whether your cache paid off? LangWatch now tracks every Claude Code session: tokens, costs, cache hits, bash commands, MCP tool calls, file edits, and full terminal replays. Works with Claude Code, Codex, Gemini CLI, and opencode. Free for individuals. Start with: npx langwatch claude
This is the 4th launch from LangWatch. View more
Claude Code usage tracking by LangWatch
Launching today
Track Claude Code usage: cost, cache, session replay. Run `npx langwatch claude` once. Every session gets cost with cache reads/writes as separate token classes, every bash and MCP call as a span, theoretical vs billed for your Max plan, and a full terminal replay in the UI. Works for Codex too.

great product! knowing the per-seat cost but not which sessions burned is a proper problem, especially as the costs keep rising. this is going to save me from getting broke!

@lina_dikhtiaruk hope ai coding solutions will also bring your team / product / company the speed and competitie advantage to win the game and get more revenue in ,! But we’ll def be there to nbe more efficient
I really enjoy seeing having a completing picture of all subagents per skill. then associated by model? and even having the granular cost? ok that was nice.

This solves a problem many developers don't realize they have until the AI bill shows up. And if they have setup the credit card that's a red zone LOL

This is such a killer feature for heavy users and big teams with distributed sessions leveraging multiple providers! Great work, @LangWatch !
Congrats on shipping this! Finally a way to know exactly how much those late-night Claude Code sessions are costing me. My wallet thanks you already!
