Where Bubble hits its ceiling
Where Bubble hits its ceiling.
The four limits that end serious Bubble projects, made specific to this comparison. Each one is sourced.
Search-performance cliff around 50k records
~50k rowsBubble's sorted searches cap near 50,000 records and lists degrade before that. AppSheet's cap is 100,000 rows per app but with a roughly 5MB compressed data cache, and Google's own docs warn performance degrades well before the limit. Both are fixed platform ceilings you tune around inside the tool rather than remove.
MajorSources: [4]Zero code ownership
No exportBubble has no source-code export. AppSheet is the same on ownership — you keep your data in your own Sheets, SQL, or BigQuery, but the app, UI, and automations are locked to AppSheet and non-exportable. Neither gives you a deployable application to take with you, so leaving either is a rebuild of the app layer.
BlockerSources: [5]Workload-Unit billing scales with activity
$0.30 / 1k WUBubble meters app activity as Workload Units, billed around $0.30 per 1,000 WUs above your allowance, so cost climbs with usage. AppSheet charges per user per month instead, so its cost climbs with how many people use the app — the licensing model is the sharpest difference between the two.
MajorSources: [4]300-second server-workflow timeout
300sLong-running server workflows in Bubble die at 300 seconds, so heavy jobs must be chunked or moved off-platform. AppSheet's bots and tasks run within their own bounds and aren't a general backend, so both platforms push serious processing elsewhere — the point at which an owned backend earns its place.

Where AppSheet hits its ceiling
Where AppSheet hits its ceiling.
The real, researched limits on AppSheet — not generic ones. If a limit matters to your app, it's here.
100k rows and a ~5MB app-data cache per app
~5MB cacheAppSheet caps an app at 100,000 rows and 1,000 columns, and total cached app data must stay under roughly 5MB compressed (10MB on some devices). Google's docs are explicit that performance degrades well before the limit. The cache ceiling is the least-known but most project-ending AppSheet limit: a data-heavy app slows or breaks long before the row count looks alarming.
BlockerSources: [2]Google-ecosystem lock-in
AppSheet is fully hosted on Google's cloud with no self-host, Core is bundled into paid Google Workspace, and Enterprise Plus requires Workspace Admin status. Your data can live in your own source, but the app, logic, and automations are locked to AppSheet. It's a different lock-in than Bubble's, not a lighter one — you're inside Google's ecosystem rather than Bubble's.
MajorSources: [1]Public / branded apps are gated and not guaranteed
Apps run inside the shared AppSheet container by default. A branded, white-label native app to the App Store or Play requires an advanced subscription, and Apple's review approval isn't guaranteed. For a public, customer-facing product under your own name, AppSheet fights you — it's built for internal Workspace apps, which is exactly the line between it and Bubble.

Pricing compared
What each one costs when it stops being a demo.
The sticker price rarely decides it. What matters is the axis your bill grows along once real users arrive.

Bubble
from ~$32/mo- Billing model
- Usage-metered Workload Units on top of a plan tier
- What drives cost up
- Workload Units consumed by app activity
Includes database, logic, and hosting; overage runs about $0.30 per 1,000 WUs, hard to forecast before real traffic.
AppSheet
$5/user/mo (Starter)- Billing model
- Per-user (per-seat) subscription
- What drives cost up
- Number of app users (seats)
Core $10/user/mo (bundled in most paid Workspace plans), Enterprise Plus $20/user/mo. Publisher Pro ($50/mo per app) covers unlimited users for public, no-sign-in apps.
What happens at scale
AppSheet is cheap when it rides an existing Workspace subscription, but per-user pricing climbs with headcount and the ~5MB cache caps app complexity. Bubble bills usage instead of seats. Neither yields an app you own, so at real scale both point toward a database and app layer you control.
Which one should you choose
The honest pick-this-if split.
Pick Bubble if…
- You need a customer-facing app, not an internal Workspace tool.
- Your app needs its own data model and deeper logic than expressions allow.
- You're not tied to the Google ecosystem.
- You expect data or app complexity to grow past the ~5MB cache limit.
Pick AppSheet if…
- Your team already runs on Google Workspace.
- You need internal data-collection or field apps over Sheets, SQL, or BigQuery.
- Expression-driven bots and automations cover your logic.
- Your data volume and app complexity stay modest.
The named limit
The ceiling nobody reads: a ~5MB app-data cache
AppSheet's headline limit is 100,000 rows per app, but the one that actually ends projects is quieter: total cached app data must stay under roughly 5MB compressed (10MB on some devices), and Google's docs say performance degrades well before you reach it. Because AppSheet syncs data to the device, a rich app with images, many columns, or wide tables can choke on the cache long before the row count looks high. It's a device-memory constraint, not a database one — the same class of limit that ends Adalo apps early. A real backend serving a real app UI has no such per-device cache ceiling.

When neither is the answer
When the honest answer is code you own.
AppSheet and Bubble solve different problems, but they share the same ending: the app and its logic are locked to the platform, only the data leaves. AppSheet is excellent for internal Workspace tools until the ~5MB cache or per-seat costs bite; Bubble carries a customer-facing app but caps its data and gives you no code. When the app becomes something the business depends on, a rebuild in code you own removes the caches, the per-seat pricing, and the ecosystem lock-in at once.
Frequently asked
AppSheet vs Bubble — the questions buyers ask.
Straight from the People-Also-Ask box on the live search results. Answers grounded in the sources cited on this page.
- Q01Can AppSheet build a real public web app, or only internal tools?
- It's built for internal tools. Apps run inside the shared AppSheet container by default, and a branded, public native app requires an advanced subscription with Apple approval not guaranteed. Bubble is designed for customer-facing apps. If you need a public product under your own brand, AppSheet fights you and Bubble doesn't.
- Q02How many records can AppSheet handle before it slows down vs Bubble?
- AppSheet caps at 100,000 rows per app but really at a ~5MB compressed data cache, and Google warns it degrades well before the limit because data syncs to the device. Bubble caps sorted searches near 50,000 records. Both slow before their stated ceilings; AppSheet's device-cache limit tends to bite on rich, image-heavy apps sooner than a raw row count suggests.
- Q03Do I own my app if I leave AppSheet — can I export the code?
- No. Your data stays in your own Sheets, SQL, or BigQuery, but the app, UI, and automations are locked to AppSheet and non-exportable. Bubble is the same with no export at all. On code ownership both are dead ends, which is why a product that must last usually gets rebuilt in code you control.
- Q04Is AppSheet cheaper than Bubble for a customer-facing app?
- Usually not, once it's customer-facing. AppSheet's per-user pricing is cheap for internal teams (especially bundled in Workspace) but scales badly with public users, and public apps need Publisher Pro or Enterprise. Bubble's usage-metered model fits public apps better. For internal Workspace tools AppSheet wins on cost; for a public product Bubble is the closer fit.
- Q05Does AppSheet work without Google Workspace?
- It can, but it's built around Google's ecosystem — Core is bundled into paid Workspace, Enterprise Plus needs Workspace Admin status, and everything runs on Google's cloud with no self-host. If you're not in Workspace, much of the value and pricing advantage disappears, which is part of why the ecosystem lock-in is the sharpest differentiator against Bubble.
