Headroom lists free tiers on developer services — hosting, databases, auth, email, monitoring, CI, storage, and a few neighbours.
Every link was opened on 12 November 2026. Limits appear only when the provider's own pricing page (or the official limits page it links to) printed them that day. Pricing changes often, so treat a figure as a starting point and check before you ship.
If a page did not show a lasting free plan, the service was left out. A trial that turns into a paid plan is not a free tier.
Picks are our opinion, labelled as such. Nobody pays to be listed or picked. Descriptions are written by us, not copied from marketing pages. Spot something wrong? Tell us.
