Coverage
We searched 2 places where competitors live — transparent about what we covered and what we missed.
Should you build this?
- Demand validated by 603-star GitHub claude-usage repo · users actively self-rolling solutions
- Anthropic's Opus paywall-within-paywall trigger is fresh · users adopting cost tools NOW
- Caveman-prompt 3× savings demonstrates clear willingness to optimize · they'll pay for automation
- Anthropic could ship native usage dashboard for Pro/Max users any quarter · platform risk acute
- Free open-source phuryn/claude-usage already exists with 603 stars · paid version must offer team/enterprise features that solo devs don't need
- Audience is technical (backend devs) · they'll build their own if your price is high relative to OSS
- This weekend: DM 5 stargazers of phuryn/claude-usage (603 stars) + 3 commenters on reddit:claudecode "Opus paywall-within-paywall" thread · ask if they'd pay $9/mo for team-shared cost tracking
- Next 7 days: Ship landing page comparing caveman prompts vs normal prompts cost-per-task · embed live calculator using user's pasted Anthropic invoice · collect emails of devs who saved >$50/mo
- If 10+ signups paying >$200/mo: If 10+ devs say they spend >$200/mo on Claude Code: build team dashboard MVP in 1 weekend on phuryn fork · charge from day 1 at $9/seat/mo

I want to build a tool for: Claude Code Pro/Max subscribers tracking token usage and costs after Anthropic gated Opus behind paywall-within-paywall · seeking local dashboards The pain users describe: i started talking to Claude like a caveman. my credits lasted 3x longer. i'm not joking. Timing / why now: Anthropic locked Opus behind paywall-within-paywall for Pro users in Claude Code · credit dynamics shifted forcing cost-tracking tool adoption Existing alternatives: claude-usage, SWEObeyMe, CodeAgent Mobile Help me draft an MVP technical plan: 1. Core user flow (happy path, 3-5 steps) 2. Data model (main tables and their key fields) 3. Tech stack recommendation (favor fast-to-ship options) 4. First 3 things to build this weekend 5. What NOT to build in v1 (scope discipline) Context source: gapmine.com/opportunities/2026-04-28/claude-code-status-widget
