Claude Counter exposes Claude's real limits
She-llac’s post reverse-engineers Claude’s plan limits from suspiciously precise floating-point usage values and argues that Anthropic’s Pro and Max plans are materially better value than API pricing for most users. The write-up also points to Claude Counter, a browser extension that surfaces token estimates, cache timing, and usage bars directly in Claude.ai, making the underlying limits easier to monitor in real time.
// ANALYSIS
Hot take: this is less a “hack” than a reminder that product telemetry leaks can become a user-facing feature fast.
- –The most interesting part is the side-channel discovery: the author claims unrounded doubles in Claude’s generation responses make the real plan math recoverable.
- –Claude Counter sounds genuinely useful for heavy Claude users who want visibility into usage, cache state, and reset timing without hopping between pages.
- –The value argument is strong: if the numbers are right, Anthropic’s subscription tiers look dramatically cheaper than equivalent API usage.
- –This is niche, but it lands squarely in the dev-tool / Claude power-user lane, where transparency tools can spread quickly.
