Best Free Stack for a Side Project

Published 2026-04-04 · Not yet reviewed

Build your side project without worrying about costs. Every service here stays free for hobby use.

Side projects need services that stay free forever — not free trials that expire. This stack uses genuinely free tiers with no credit card required. Optimized for solo developers who want to ship fast and keep costs at exactly $0 for as long as possible.

$0 covers the 3 of 6 picks whose free tier our own badge still reads as active. It does not cover Render (at risk), Firebase (at risk), Brevo (unrated — change not established).
