Retool vs Bubble: Internal Tool or the Product You Actually Ship?

Updated August 2026

You're an IT director, ops lead, or founder with a shortlist that has both Retool and Bubble on it, and that alone is worth pausing on. These two tools get compared constantly, and almost never because they solve the same problem. Retool builds internal tools: the admin panel your support team lives in, the ops dashboard sitting on top of a database you already run, the console nobody outside your company will ever see. Bubble builds the product itself: a customer-facing web app, and now a mobile one too, with its own database, its own user accounts, and its own signup flow, something you'd eventually put a price on and sell.

Get that distinction wrong and every feature row below will mislead you. The second thing that decides this comparison, and the reason the two vendors' bills behave nothing alike, is what each one meters. Retool charges per person, by role: a builder costs $50 a month on Business, an internal user costs $15, and your first 50 external users are free. Bubble doesn't count people at all. It charges a flat plan price plus workload units, a measure of how much your app actually does, so the bill moves with traffic and backend activity, not headcount. One cost scales predictably with your team size. The other scales with how busy your product gets, a genuinely different kind of risk to sign up for.

TL;DR

What Each Tool Is Actually Built For

Retool starts from the assumption that your data already exists somewhere: a Postgres database, a REST API, Stripe, Salesforce, an internal microservice. You connect to what you already have, then drag together tables, forms, and buttons that read and write against it. Nothing about Retool wants to become your system of record. It wants to be the fastest possible UI layer on top of the system of record you already run, built by and for people who already work at your company.

Bubble starts from the opposite assumption: that nothing exists yet. You define your own data types inside Bubble's own database, design pages visually, and wire up logic with its no-code workflow engine, and the result is a complete, deployable web application, or, since Bubble's 2025 mobile launch, a native app too, with its own signup and login flow, its own hosting, and its own domain. Bubble isn't a layer on top of your business. It is the software your business runs, or sells, or gives away to the public.

Key Facts

• Bubble has powered more than 6 million apps across 180+ countries, with over $850 million transacted through the platform, per Bubble's own June 2025 announcement of native mobile support.
• In Retool's 2025 Builder Report (1,128 builders surveyed in July 2025), 48% of non-engineers said they now build production-ready solutions independently, without waiting on an engineering team.
• 85% of the 100 SaaS companies Metronome and Greyhound surveyed in January 2025 had adopted usage-based pricing in some form, and 77% of the largest software companies use some level of consumption pricing, per Orb's compiled SaaS pricing statistics, the exact billing shape behind Bubble's workload units.
• By 2026, developers outside formal IT departments will make up at least 80% of the low-code user base, up from 60% in 2021, per Gartner as reported by InfoWorld, the same shift that put a citizen-developer builder like Bubble and an ops-team builder like Retool in front of non-engineers at once.
• Solo founders made up 36.3% of new U.S. startups in 2025, the highest share in more than 50 years, per Carta's Solo Founders Report, close to the audience Bubble's no-engineer builder targets and Retool, built for teams with an existing engineering or ops function, generally does not.

Decision by Business Goal

Team and Role Fit

Core Capability and Builder Model

Retool's builder assumes you already know your data. Connect to a Postgres or MySQL database, a REST or GraphQL API, or one of dozens of pre-built integrations (Stripe, Salesforce, Slack, Google Sheets), and Retool's component library, tables, forms, buttons, charts, snaps onto whatever comes back. Every query can be raw SQL or JavaScript. There's no abstraction layer hiding the underlying system from you, which is the whole point: Retool is a UI, not a database.

Bubble's builder assumes the opposite. There's no existing data to connect to, so Bubble gives you one: define data types and fields inside its own built-in database, then design pages visually and wire up logic in the Workflow tab, if/then branching, custom events, backend workflows on a schedule or via API. No SQL, no JavaScript required, though a plugin marketplace and an API connector let a technical builder push past the visual ceiling when needed.

If the actual requirement is technical depth beyond either tool's ceiling, that's the territory our Retool alternatives guide and our Retool vs Softr vs Budibase comparison both cover in more depth.

Two Different Meters: Seats Versus Workload Units

This is why a plain side-by-side pricing table can mislead you if you don't read past the dollar signs. Retool counts people. Every builder, internal user, and external user past the free 50 adds a line to the bill, knowable in advance because your org chart already tells you who needs a login. Bubble counts activity: page loads, database operations, and backend workflow runs, rolled into a single number called workload units (WU), resetting every month regardless of who's logged in. A Bubble app with 5 quiet users and a heavy backend job running hourly can burn through more WU than one with 500 people who barely touch it.

Pricing at Real Team Sizes

Do the math with each vendor's own published numbers, not a sibling article's numbers. Retool bills by role, annually by default, with a higher rate if you pay monthly. Bubble bills the app, and the web-only figures below are deliberately separate from the web-and-mobile figures, because printing one without the other is the single most common pricing mistake made about this tool.

Retool's published tiers, per Retool's pricing page, verified August 2026:

Self-hosted deployments bill at the same per-role rates, with Team and Business self-hosted capped at 100 total users.

Bubble's published tiers, per Bubble's pricing page, verified August 2026. Every figure below is web only; web and mobile runs meaningfully higher on every paid tier.

Bubble's Free plan is development-version only: no live app, no custom domain, so it can't host anything a real user would ever reach. Bubble's page advertises "save up to 20% annually"; the figures above are already the annual basis. File storage is a separate add-on at $3 per 100 GB/month on every paid tier.

What 10, 25, and 100 users actually cost

For Retool, assume a realistic ops team: a handful of people building and maintaining tools, and everyone else just using what gets built. At 10 users, assume 2 builders and 8 internal users. At 25, assume 3 builders and 22 internal users. At 100, assume 5 builders and 95 internal users, all priced on Business, since Team lacks external-user support and some of the governance controls most 100-person deployments will want. For Bubble, the same 10/25/100 framing measures something else: end users of the app you built, meaning customers or members, not staff. Headcount barely moves that bill. What moves it is workload, how much those users actually do inside the app, and how many people on your team need an editor seat to keep building it.

The point of that last column isn't the specific dollar figures, it's that Bubble's row doesn't move the way Retool's does. Ten lightly active users and a hundred lightly active users can land on the exact same plan. Ten users hammering a data-heavy backend workflow can force an upgrade that a hundred passive browsers never would. If your business case depends on knowing the bill in advance, that's a difference in kind, not just in degree, from Retool's per-seat model.

Who Logs In: Internal Staff Versus Paying Customers

That distinction compresses the whole article into one question: who is this app for? If the honest answer is "people on my payroll," Retool's per-seat model prices exactly what you're adding: another person with access. If it's "people who don't work here and might pay us," Bubble's workload model prices exactly what you're building: a product whose costs should track its own usage. If Bubble's own hosting still feels like more lock-in than the build warrants, our Bubble vs Softr comparison covers a lighter alternative built on an existing no-code database instead of Bubble's own.

Implementation and Change Management

Risk, Governance, and Lock-In

Retool's biggest structural advantage shows up here, not in the feature list. Because Retool never owns your data in the strict sense, the underlying database or API stays exactly where it was before you ever opened the builder. Walk away from Retool tomorrow and your data isn't stranded; only the admin panel built on top of it is. Self-hosting and VPC deployment exist on paid plans for teams that need the tool running inside their own infrastructure, a real answer to a real compliance question.

Bubble's structure is different by design, because the whole point is that Bubble is the product, not a layer on top of one. The app's data and logic both live inside Bubble's own runtime, and there's no self-hosted option, no way to export the finished app as portable source code a developer could pick up and run elsewhere. Migrating off Bubble later means exporting the data (which Bubble does support) and rebuilding the logic by hand in whatever comes next. That's the honest trade-off behind every visual, no-code builder, covered further in our Bubble alternatives guide: build speed today, in exchange for portability later.

If Microsoft-ecosystem ties and deeper enterprise governance matter more than either vendor here, our Power Apps vs Retool comparison is the more relevant read. And if the requirement is a heavier internal-tools platform with its own compliance ceiling above what Retool offers, our OutSystems alternatives guide covers that end of the market.

When Retool Is the Right Call

• Your data already lives somewhere real: a production database, a set of internal APIs, a stack of SaaS tools you already pay for, and you need a UI on top of it, not a new place to store anything
• The people who'll use what you build are on your own payroll, and you want a bill that scales in a straight line with exactly who has access
• Someone on the team is comfortable with SQL or a REST API, and you want that power available inside the builder, not walled off behind a visual-only ceiling
• Self-hosting or VPC deployment is a real requirement, not a nice-to-have, because of where your company operates or who regulates it
• You're building an internal console, not a product with its own customers, signups, or billing

When Bubble Is the Right Call

• You're building the actual product: a customer-facing web or mobile app with its own users, its own data, and its own reason to exist independent of anything else you run
• You don't have an engineer on the team yet, or don't want to hire one before validating the idea, and the visual builder is meant to close that gap entirely
• You need real native iOS and Android apps from the same build, not a responsive page resized for a phone
• You'd rather have a bill that tracks your product's own usage than one that grows every time you add a teammate
• You're comfortable with the trade-off: fast to build, harder to walk away from later, because the app's logic and data live entirely inside Bubble's own runtime

If neither shape fits because the actual need is a fast, mobile-first build for field or frontline staff rather than an office admin panel or a full customer product, our Glide alternatives guide covers that narrower, table-first category instead.

Decision Framework

What to Do Next

1. Answer the one question that decides most of this: who logs in? Your own staff on top of data you already run, start pricing Retool. Customers or the public with their own accounts, start pricing Bubble.
2. Model your actual headcount split for Retool before picking a tier. Builders and internal users cost different amounts; a rough guess changes the annual number meaningfully at 25 or 100 people.
3. Don't quote a Bubble price without saying web only or web and mobile. The gap between $29 and $59 a month on Starter alone is real money at any size, and printing the wrong one is the single most common mistake made about this tool.
4. Rebuild your single most complex screen in both tools before committing. For Retool, that's the screen with the heaviest query. For Bubble, it's the screen with the most conditional workflow logic.
5. Still not sure either shape fits? Our best no-code app builders roundup widens the search.
