Of the seven builders we write about, Bubble is the one where our honest answer is most often "not us". Bubble's subject is applications: data, workflows, permissions, logic. Birta serves static files. Those are different products, and pretending otherwise would waste your afternoon.
So this page does two things. It starts with the case where the whole category is a mistake, because a surprising number of Bubble projects are a site wearing an app costume, and the prompt below settles that in an afternoon. Then it gives you the real Bubble alternatives for when it genuinely is an application.
One prompt: try the site without an app platform
A surprising number of Bubble projects are a pricing page, a portfolio, a service page with an enquiry form or a launch page. None of those needs a database or logins. They need to be correct, findable and reachable at an address, and you almost certainly already pay for something that writes them.
So build the page first, before you commit to a platform. Paste this into Claude or ChatGPT.
Build this as a single static bundle: index.html plus one style.css, no build
step, no framework, no client-side router. Multi-page is fine as separate
.html files that link to each other.
What it is: [one sentence]. Who it is for: [one sentence]. The one action:
[what you want them to do].
Style: [two words], and specifically oversized headline, high contrast, one
accent colour, generous whitespace, system fonts. Real copy, no placeholder
text.An afternoon with that prompt settles the question better than any comparison table. If the page is what you needed, you are done and a six-week app build never happens. If you hit something that genuinely has to remember a person between visits, then it is an application and the table at the bottom is your list.
Time it against a Bubble build of the same thing if you want the number. Ours is not the one that matters. The prompts that publish the result and collect a client's remarks are in AI website prompts.
The one fact to read before choosing anything
Bubble states it in its own documentation, and it is the single most decision-relevant line in this whole comparison:
"Bubble apps can only be run on the Bubble platform; there's no way of exporting your application as code."
Data comes out. You can export user-created data as CSV and read the database through Bubble's API. The application logic does not: their own page says that if you leave, "you'll have to rebuild the application logic, although we can help you export the design." They also commit to releasing their source under an open-source licence if the company ever discontinues operations, which is a more thoughtful backstop than most platforms offer.
None of that makes Bubble a bad choice. It makes it a considered one. If you are going to build your business on it, know that the exit is a rebuild and price that in now rather than in year three.
If it is genuinely an application, this is not us
- The app has user accounts, a database or permissions. This is Bubble's core, and Birta has no equivalent: it serves static browser files.
- It runs server-side logic or scheduled workflows.
- It is a single-page app with client-side routing. On a static host, unknown paths return 404.
- It takes payments on your own site. Not something Birta does yet.
What Birta is for, stated plainly
The static case, and only it. When the agent has written the files:
- Publish from the same conversation, and get that version's own permanent address back.
- Versions and rollback, so any publish is recoverable.
- A review link needing no account, remarks pinned to page elements on a frozen version, read back by your agent and fixed in the same draft. It cannot reply in the thread or resolve one.
- A declared lead form, with submissions in the project panel plus an email digest roughly fifteen minutes after the first one.
Free tier covers that. A custom domain needs Solo or Pro; the badge stays on the free tier.
The honest alternatives
For the application case, these are the real options, and Bubble is a strong entry on this list rather than the thing to escape.
| Instead of Bubble | What it is for | Worth knowing |
|---|---|---|
| Adalo | Mobile-first no-code apps | Closest in spirit for consumer app shapes |
| Glide | Apps over data you already keep in a sheet or database | Fast when the data exists already |
| Softr | Client portals and internal tools over existing data | Strong at portals, weaker at bespoke logic |
| WeWeb | Front end you own over your own backend | Aimed squarely at avoiding platform lock-in |
| Retool, Blaze, Tadabase | Internal tools and business apps | Where compliance and admin workflows matter |
| Base44 | Prompt to app with auth and a database | Two-way GitHub sync requires its Builder plan or higher |
| Lovable or Bolt.new | Prompt to app, code you can take | The AI-native end of this list |
| Your agent plus a static host | Only if the project turned out to be a site | No database, no accounts. That is the whole condition |
If two rows fit, weigh the exit. Bubble tells you the exit is a rebuild, which is more than most platforms admit, and a platform that hands you code is easier to leave later even if it is slower to start.
If it turned out to be a site, publish it today
