The short version

  • Each has a real cost: Budibase cloud plans are metered on automation actions, from 5,000 a month on Pro to 250,000 on Business; OpenSearch diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • They diverge on capability: Budibase covers Drag-and-drop builder, OpenSearch covers Full-text search.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Budibase

  • Cloud plans are metered on automation actions, from 5,000 a month on Pro to 250,000 on Business
  • Creator seats are limited and cost $50 each beyond the included count
  • End users are $5 per user per month on top of the plan
  • Custom branding needs Premium, SSO enforcement and environment variables need Business, and audit logs are Enterprise only
  • Log retention is tiered from 1 day on Pro to 365 days on Enterprise
  • Monthly billing costs 20 percent more than annual

OpenSearch

  • Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
  • Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
  • Overkill for plain application search, where a dedicated search engine is far simpler

Answered from the vendors’ own pages

Budibase: What happens if I exceed the monthly action limit on my plan?

Actions are hard monthly limits. Once you reach the limit on your plan (5K for Pro, 20K for Premium, 250K for Business), you must upgrade to a higher tier to continue using the service.

Source
OpenSearch: Is OpenSearch free?

Yes, Apache 2.0 licensed under the Linux Foundation. Amazon OpenSearch Service is a paid managed option.

Budibase: Is there a charge for additional users beyond what is included in my plan?

Yes. Each plan includes a limited number of creators (1 for Pro, expandable for Premium, 3 for Business), but end users are charged at $5 per user per month as an add-on.

Source
OpenSearch: Why does OpenSearch exist?

Elastic moved Elasticsearch off the Apache 2.0 licence in 2021. AWS forked the last Apache-licensed version, and the project now sits under the Linux Foundation.

Budibase: How much extra do I pay if I choose monthly billing instead of yearly?

Monthly billing costs 20% more than the yearly equivalent. For example, paying monthly for Pro at $19/month equals $228 per year, versus $190 per year on a yearly subscription.

Source
OpenSearch: Is OpenSearch compatible with Elasticsearch?

It was at the 7.10 fork point. Both have developed independently since, so compatibility weakens with every release and should be verified for the features you use.

Budibase: Can I try Budibase before committing to a paid plan?

Yes. All paid cloud plans include a 14-day free trial. The open source version is also available free with unlimited actions and unlimited users, though with community support only.

Source
Budibase: Does the free open source plan include the same features as paid plans?

The open source plan includes unlimited actions, unlimited apps, automations, agents, and users, but support is community-only rather than through Budibase directly. Paid plans add features like AI credits, custom branding, backups, and email or priority support.
