FAQ — for the record

## Common questions.

### Q.01What counts as "production use"?

Any deployment that serves real users, processes real data, or runs as part of a business operation. Internal tools your team uses for day-to-day work also count as production.

### Q.02Can I use it for free during development?

Yes. The Community plan covers local development, testing, CI/CD pipelines, demos, prototypes, personal projects, and open-source contributions. No restrictions.

### Q.03What happens after the BSL Change Date (2030)?

The license automatically converts to `Apache 2.0`. After that date, all versions released before it become fully open source with no production restrictions.

### Q.04Is there a free tier for startups?

If you're a bootstrapped startup with fewer than 5 people and under $100k ARR, reach out — we offer discounted or free production licenses on a case-by-case basis.

### Q.05Do I need a license per server?

No. The Pro license covers your entire team (up to 10 members) regardless of how many servers or instances you run. Enterprise is unlimited.

### Q.06Can I modify the source code?

Yes. All plans allow you to modify, fork, and create derivative works. Your modifications remain under BSL 1.1 terms (or Apache 2.0 after 2030).

### Q.07How do I get an invoice for my company?

Pro and Enterprise plans include commercial invoices. Email tom@pflanzer.cz with your company details and we'll send a proper invoice.

### Q.08What if I need custom terms?

The Enterprise plan includes custom license agreements. If you need specific clauses — indemnification, data processing, SLA — we can work with your legal team.
