An unofficial dated ledger of pricing & usage-limit changes for AI coding tools

I put together a small, unofficial public ledger that records dated snapshots of the public pricing, usage limits, and rate limits of a few AI coding tools — currently Cursor, GitHub Copilot, and Claude Code — and keeps the history so you can see what changed over time. Why: pricing and quota pages change in place. The old value disappears from the live page and there is usually no public diff. If you are budgeting a team or comparing tools, the history is the useful part, and it is the part the live pages do not keep. What it is / isn't: - It records only factual public values (a price, a numeric limit) plus a short source attribution and capture date. It does not reproduce vendor pages. - "silent" / "quiet" here means only that a change was not paired with a prominent announcement when it was recorded. It makes no claim about any vendor's intent. - Unofficial. Not affiliated with any vendor. The vendor's official page is always authoritative. No affiliate links, no "best tool" ranking. - Early stage: this is an initial snapshot; a daily automated capture is planned but not yet running.
