FIREBASE STUDIOSUNSET SINCE 2 AUGUST 2026Firebase Studio has had an access tier withdrawn; check what is still available before choosing it. firebase.studio carries a banner: "We're sunsetting Firebase Studio on March 22, 2027 so you can no longer create new workspaces. Move your code to Google AI Studio or Google Antigravity." Still usable until then, but it is not a tool to start a project on.
On the prices each vendor publishes about itself, Firebase Studio starts at Not read and Replit Agent at Not read. Before that decides anything: Firebase Studio has had an access tier withdrawn; check what is still available before choosing it. (since 2 August 2026) Neither takes your own API key, both bundle model usage, and on both the headline price is an allowance rather than a bill. Every figure on this page was read from the two vendors' own pages in last night's run rather than written down once, which is the only reason it is still the current answer. ToolDrift sells neither and takes no referral fee on either.

Is Firebase Studio or Replit Agent cheaper?
On the cheapest option each vendor publishes: Firebase Studio is Not read and Replit Agent is Not read. Treat both as an allowance rather than a bill, every tool in this category meters model usage on top of the plan, and which one costs more in practice depends on the models you drive and how hard. The tier prices are the part that can be checked from outside, so they are the part this page prints.
Can I use my own API key with Firebase Studio or Replit Agent?
Firebase Studio: no, model usage is bundled. Replit Agent: no, model usage is bundled. It is the row that decides whether the subscription price is most of what you pay or a fraction of it: a tool that takes your own key charges for the software, and one that does not is reselling inference with a margin you cannot see.
Are Firebase Studio and Replit Agent still maintained?
Sunset and Active as of last night's read. Firebase Studio publishes no repository this site tracks, so there is no push date to read; Replit Agent publishes no repository this site tracks, so there is no push date to read. One caution: Firebase Studio has had an access tier withdrawn; check what is still available before choosing it. (since 2 August 2026) This is the question a written comparison cannot answer, because it was true on the day it was published and nobody went back.
