Why we chose our own compute over AWS Lambda Web Functions
Summary
The Easel.sh team found that AWS Lambda Web Functions continue to bill memory for 5–7 minutes after the last request, prompting them to build their own compute. They claim the self-hosted compute delivers faster warm and cold-start performance and lower total costs in practice, and they detail a benchmark comparing their setup to Lambda Web Functions. The result is a recommendation to move to self-operated infrastructure for cost predictability and performance at scale.
