The short version
- Each has a real cost: Teable the automation builder is far less capable than the established commercial alternatives, so multi step workflows usually end up in an external tool that must be paid for and maintained separately.; Windmill free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
- They diverge on capability: Teable covers PostgreSQL native storage, Windmill covers Script-to-workflow engine.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Teable
- The automation builder is far less capable than the established commercial alternatives, so multi step workflows usually end up in an external tool that must be paid for and maintained separately.
- Self hosting moves PostgreSQL backups, version upgrades, connection pooling and capacity planning onto your team, and the licence saving disappears if that time is costed honestly.
- The integration catalogue is small, so connecting to a common business system often means writing against the REST API rather than installing a connector.
- The project is young relative to the products it replaces, and interface and API changes still arrive at a pace that requires reading release notes before upgrading.
- Storing every table as a real PostgreSQL table means schema changes are real migrations, so a careless field type change on a large table can lock it far longer than a spreadsheet user would expect.
Windmill
- Free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
- Compute unit and seat-based pricing (developer vs. operator seats, worker compute units) adds pricing complexity beyond a flat monthly fee.
- Email triggers are capped at 100/day on the free tier, limiting event-driven use cases without upgrading.
- Smaller ecosystem of pre-built integrations compared to more established automation tools like n8n.

Answered from the vendors’ own pages
Teable: How many rows can it actually hold?
As many as your PostgreSQL instance can serve. There is no product imposed record limit on the self hosted edition, which is the main reason to choose it.
Windmill: What does Windmill cost?
Windmill's Free and Open-source edition is $0/month for self-hosted use with unlimited executions, while Enterprise starts at $120/month with unlimited workspaces and uncapped SSO seats, priced further by developer/operator seats and compute units.
SourceTeable: Can I query the data with SQL directly?
Yes. Tables are real PostgreSQL tables, so any SQL client or reporting tool can read them.
Windmill: Is there a free plan and what are its limits?
The free self-hosted plan supports unlimited executions but caps SSO at 10 users, workspaces at 3, groups/permissions at 4, and email triggers at 100 per day.
SourceTeable: Is self hosting genuinely free?
The licence is. The database server, backups and the engineer maintaining them are not.
Windmill: How is usage metered on Windmill Enterprise?
Enterprise usage is metered through seats (developer seats at $20/month, operator seats at $10/month) and compute units, e.g. $100/month for 2 standard-worker compute units.
SourceTeable: Does it replace Airtable feature for feature?
No. Views and field types are close; automations, apps and the integration catalogue are not.
Windmill: What happens to a self-hosted Windmill deployment if the company shuts down?
The pricing page addresses this directly as an FAQ topic, noting that self-hosted applications built on the open-source edition can continue running independently of Windmill the company.
SourceTeable: What happens to my data if the project stops?
It remains in a standard PostgreSQL database that you control, which is a materially better exit than a proprietary export format.
