Know what AI costs.
Know what it's worth.
100xPrism auto-discovers every project you build across every AI coding tool and shows what each session cost in tokens next to what it actually shipped — cost and value, automatically, fully offline.
Leverage scatter — value vs cost

What is 100xPrism?
100xPrism is a fully-offline, machine-wide developer toolkit that auto-discovers every AI coding session across Claude Code, Cursor, Codex, Windsurf, GitHub Copilot, Gemini CLI, and Antigravity. It measures what each session cost in tokens and what it actually delivered — commits, pull requests, files changed — so you can see cost and value side by side, automatically, without uploading anything to any server.
"Not 'can it ship', but 'what did it cost, and what was it worth' — and that's everybody's responsibility, not one person's job."
The Token & Value Dashboard
Run 100x-tokens or 100x-value. A daemon auto-starts and the dashboard opens in your browser — no setup required.
- Auto-discovery — reads Claude Code transcripts and does a machine-wide scan for agent files (
CLAUDE.md,AGENTS.md,GEMINI.md,.cursorrules) to find every directory you build in. - Tool-agnostic value measurement — reads git history for commits, PRs, and files changed, with a filesystem fallback for directories not in git.
- Four charts — leverage scatter (value vs cost), cost over time, token-purpose split (input/output/cache), cost by directory.
- AI one-line summaries per project — a quick characterisation of what the session delivered.
- Fully offline — no data leaves your machine. Everything is computed locally and displayed in your browser.
- Two commands:
100x-tokensfor the cost dashboard and100x-valuefor the value report — both auto-start the daemon.

Frequently Asked Questions
What is 100xPrism?
100xPrism is a machine-wide, fully-offline developer toolkit that auto-discovers every AI coding session you run across Claude Code, Cursor, Codex, Windsurf, GitHub Copilot, Gemini CLI, and Antigravity. It shows what each session cost in tokens next to what it shipped, so you can see cost and value side by side.
How does 100xPrism measure cost?
It reads Claude Code transcript files (and equivalent agent logs for other tools) from your local machine. It counts input tokens, output tokens, and cache tokens, then maps them to estimated dollar cost using published model pricing. All computation is local — no data is uploaded anywhere.
How does 100xPrism measure value?
It reads your git history for each discovered project directory — commits landed, pull requests merged, and files changed. If git is not available for a directory, it falls back to filesystem metrics. The result is a per-project value score you can compare against cost.
Which AI coding tools does it support?
Claude Code, Cursor, Codex, Windsurf, GitHub Copilot, Gemini CLI, and Antigravity — 7 tools in total. The one-config system keeps all of them in sync from a single source of truth.
Does 100xPrism send my data anywhere?
No. 100xPrism is fully local and offline. It reads transcript files and git history on your own machine and opens a local dashboard in your browser. Nothing is uploaded to any server.
How is this different from my AI provider's billing page?
Your provider's billing page shows aggregate spend. 100xPrism breaks it down per project directory, per day, and per session — and crucially, shows what was delivered for each unit of spend. It is the only view that connects cost to value.
Is 100xPrism free?
Yes. 100xPrism is MIT-licensed and free to use, modify, and distribute. There is no paid tier, no telemetry, and no account required.
How do I install 100xPrism?
Run npm install -g 100xprism && 100xprism install (macOS, Linux, Windows). Or use the curl installer: curl -fsSL https://raw.githubusercontent.com/rajitsaha/100xprism/main/get.sh | bash. Then cd your-project && 100xprism init.
