Redis

the moat is real

17 years 132 days and counting

Salvatore Sanfilippo, 2009. Still the Swiss Army knife in RAM.

Why it lasted

  • If you need a cache, a queue, or a counter, you reach for it without a meeting.
  • The data structures are the product. Everything else is a license argument.

Times it almost ended

  • The 2024 license change and Valkey fork. The noun 'redis' survived the company drama the way 'xerox' survived Xerox.

What would finish it

  • Valkey (or a cloud default) fully taking the name in docs and job posts. Possible. The clock is still running.
