Firebase Studio, Bolt, Lovable etc.

Google Firebase Studio In 23 Minutes, https://www.youtube.com/watch?v=Rd6F5wHIysM , around 22 mins, published May 2025.

It shows development of a single page web app using AI (some pokemon or something clone which I did not understand). The author uses vibe coding mostly without getting into code changes herself with one or two exceptions. The tech stack of the app includes NextJS, React and Firebase. The interesting feature of Firebase studio as compared to what I did when I developed the Timestamp Tracker using  ChatGPT and Gemini is that the former has a VSCode based editor integrated with Gemini.

The app development did run into some issues which is similar to my experience with Timestamp Tracker development. At some point, the author changed the model to what seems to be a paid one. Firebase studio has an interesting feature of being able to modify the screen directly and ask Gemini to generate the code for it. 

Firebase studio also provides an integrated publish (for web apps) to Firebase hosting but Firebase hosting is paid (as per the author).

The author also mentions Windsurf and Cursor as more capable AI development environments which seem to have a free trial feature but may not be free for regular use.

While I have not used Firebase Studio, I would not be surprised if with free Gemini models, it may be OK for a somewhat simple single page app but as the app becomes more complex, it may either need paid Gemini models, or simply not be able to handle it well on its own.

Bolt vs Lovable: which AI app builder comes out on top?, https://www.youtube.com/watch?v=yHDvCGNjIqk , 14 min. 19 secs, published Dec 2024. The author creates a Trello like web app using Bolt and Lovable in parallel. The code for the app is not shown. The tools do trip up at times, but they are able to recover based on prompts or commands to fix the error. So what is shown is a complete vibe-coding scenario.
