How Linkup compares

- Free entry tier
- Every alternative offers a free or freemium tier. Each is testable without procurement.
- JS rendering
- Linkup and the alternatives all skip JavaScript rendering. None will work on JS-heavy SPAs without pairing with a headless browser.

- Self-hosting
- Neither Linkup nor any alternative self-hosts. All run as managed services with their own data paths.
