Bubble Rate Limits

Bubble enforces rate limits on the Data API and Workflow API at the per-app level, with the request-per-minute ceiling determined by the app's subscription plan. In addition to request rate, Bubble meters server-side activity in Workload Units (WU): every API call, database query, scheduled workflow, and plugin invocation consumes a number of WU drawn from the monthly plan allotment. Hard limits also apply to request size, response size, response list length, and workflow timeout. Rate-limited requests return HTTP 429; legacy plans return 429 (and occasionally 503 on capacity-locked legacy infrastructure).

Search response list length account
items

1000
Up to 1,000 records per Data API /bulk POST request.
API Connector recursion depth account
levels
3
Direct recursion limited to 3 levels; indirect recursion limited to 10 levels.
Workload Units (Per plan) account
wu_per_month
see plan allocation; varies by tier; per-activity costs apply
Workload meter; not a per-second rate. Each API call, database query, scheduled workflow, and plugin invocation deducts WU from the plan's monthly allotment. Sample per-activity costs: inbound API call 0.01 WU, outbound API call 0.1 WU, server-side workflow action 0.6 WU, database search 0.3 WU + 0.015 WU/thing, thing creation/modification 0.5 WU, thing deletion 0.1 WU, plugin server action 0.2 WU + 0.0005 WU/ms.

Policies

Per-app scoping
Rate limits and WU allotments are bound to the Bubble app, not the API token. Multiple tokens on the same app share the same ceiling.
Live vs version-test
The development environment (`/version-test`) draws from the same WU pool as live; do not load-test in version-test on a paid plan.
HTTP 429 backoff
When throttled, Bubble returns HTTP 429. Clients should back off exponentially. Retry-After header may indicate wait time.
Plan upgrade for higher limits
Higher request-per-minute and WU ceilings require plan upgrade or Enterprise contract. Per-tier limits are published on the Pricing page; Enterprise limits are negotiated.
Workload optimization
Reduce WU consumption via indexed searches, smaller field projections, fewer scheduled workflow chains, and client-side rendering where possible. Bubble publishes an `Optimizing workload` guide.
Hard system caps
Some limits cannot be raised by plan upgrade — workflow timeout (300s), request header size (8 KB), API key size (20 KB), API Connector recursion depth, and per-thing list length (10,000).
Privacy rule enforcement
User tokens enforce privacy rules; admin tokens bypass them. Throttling applies regardless of token type.
