📄 Description
Adds two free, client-side tools to the Introduction / Interviews section, alongside the existing interactive practice tools (e.g. Codemia):
System Design Capacity Estimator — turns daily active users into average/peak QPS, storage, and bandwidth (the back-of-the-envelope estimation step).
Rate Limiter Designer — converts a rate limit into token-bucket parameters, with the token bucket vs fixed/sliding window trade-off.
Both are free, no signup, run entirely in the browser, and cover topics that come up directly in system design interviews. Entries follow the section's format and placement. Thanks for maintaining this list!
