Bubble review

Bubble is a no-code app builder for web and native mobile apps. Its AI Agent can turn a prompt into an app you can then edit in Bubble’s visual editor, rather than leaving the generated result as a black box. You can change the design, database and workflows without writing code, including backend logic.

The platform combines web and iOS/Android app building, with apps sharing data and workflows. Bubble also lists app-store submission, connections to LLMs, payment providers and other tools through the Agent, plus hosting and infrastructure. Privacy rules are built in, and Bubble says its platform is SOC 2 Type II compliant.

The practical pitch is speed and a single platform: generate a starting point, then shape the app visually. That makes Bubble relevant to founders validating an idea and teams that want to keep product changes in a no-code editor. It also means you are building inside Bubble’s platform, not starting with a portable codebase.

Bubble’s main advantage is that the AI Agent and visual editor work together. The Agent can generate a starting app from a description; the editor gives you control over the design, database and workflows afterward. That is more useful than a prompt-only builder if the generated version needs ongoing changes. Bubble also brings web and native mobile apps, shared data and workflows, hosting, and app-store submission into one product.

For an early app, the Free plan gives you one app editor and 50,000 workload units (WU) per month in a dev-only environment. It includes 0.5 GB of file storage and six hours of server logs, but no custom domain or live deployment. The pricing page lists Starter at $32 monthly or $29 per month billed annually for a live web app, with 175,000 live WU, 100,000 dev WU, a custom domain and live deployment.

Reddit users describe Bubble as useful for MVPs and self-production. One commenter also reports using Bubble as a front end with Supabase as the backend, so the platform need not hold every part of an app.

The cost is tied to workload, so a low entry price does not tell you what a busy app will cost. Starter includes 175,000 live WU and 100,000 dev WU monthly; Growth, at $134 monthly or $119 billed annually, lists 250,000 live WU and 100,000 dev WU. Team costs $399 monthly or $349 billed annually and includes 500,000 live WU plus 100,000 dev WU. The pricing page lists pay-as-you-go overage at $0.30 per 1,000 WU without a tier. Workload Tier 1 adds 200,000 WU monthly for $29, or $26 billed annually, and lowers overage to $0.15 per 1,000 WU.

Caps matter beyond usage: Free is dev-only, Starter has one editor and one custom branch, Growth has two editors and up to 10 branches, and Team has five editors and 25 branches. Enterprise pricing is custom; native-app plan pricing is not published on the vendor's site.

Some Reddit users cite WU bills, vendor lock-in and migration work as reasons to leave. Those are individual reports, not a guarantee of what your app will cost, but they are worth weighing before building something difficult to move.

Bubble's free plan is dev-only — no live deployment, no custom domain — so it's really a sandbox for testing an idea, not a way to launch. To put an app in front of users you need Starter, which the pricing page lists at $29/month billed annually ($32 month-to-month) and caps you at 175,000 workload units (WU) live plus 100,000 WU in dev, one editor, and two days of server logs.

The real jump is Starter to Growth: $119/month annually buys a second editor, more WU, two-factor authentication, and 14 days of logs. Team runs $349/month annually for five editors and sub-apps. Enterprise is custom quote only.

Watch the workload-unit math. Burn through your tier's WU and you're charged $0.30 per 1,000 units pay-as-you-go, or you can buy a 200,000 WU block for $29/month ($26 annually) at a lower $0.15 overage rate. The 14-day trial requires a card on file with a $1 hold, and must start within 10 days of creating the app.

Bubble doesn't export runnable source code — apps live inside its editor, running on its workflow and database engine. Per the docs, you can export your data (via API connector or data export tools) but not the app logic itself, so migrating to another builder or to custom code means rebuilding workflows from scratch, not lifting and shifting.

That's the trade teams are making for the one-click AI Agent build and native mobile output. It's a fast way in and a slow way out. The pricing page's own plan descriptions hint at this: Starter and Growth are scoped for small-to-midsize live apps, and nothing in the published tiers addresses bursty or unpredictable traffic — you just pay per workload unit or get throttled.

For teams that expect to need data portability later, or that run workloads spiky enough to blow past WU caps regularly, the overage pricing and lack of code export are the two things worth weighing before committing, not after the app is live.
