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.
