Open-source projects need stable documentation, preview deployments and reproducible builds more often than a permanently running server. Static project sites have the most durable free path; public demo APIs need explicit expectations around sleep and abuse.
Use GitLab Pages when source, issues and CI already live in GitLab.
Use Cloudflare Pages for documentation, previews and edge-friendly demos.
Use Netlify when its Jamstack workflow and contributor previews save setup time.
Use Render only for a low-traffic backend demo that can sleep.
Best repository-native docs
Limit
The site must be static and builds consume project CI resources.
GitLab Pages publishes static artifacts through the same CI/CD pipeline as the source project.
Best edge documentation
Limit
Current Pages and Workers limits apply separately to builds, files and functions.
Git builds, previews, custom domains and Workers integration support docs and lightweight interactive examples.
Best contributor preview workflow
Limit
Builds, bandwidth and functions share the current plan's usage accounting.
Deploy previews make it easy to review documentation and frontend contributions before merge.
Best backend demonstration
Limit
Free web services sleep after inactivity and have monthly included usage.
Render can deploy a public Node, Python or Docker demo from the project's repository.
Keep documentation and the main project site static, portable and reproducible. Link live demos as optional evidence, not as the only onboarding path. Publish local development steps, sample environment files and screenshots so a sleeping or suspended service does not make the project look abandoned.

Use static Pages hosting for documentation and project sites. Choose from repository integration, preview workflow and edge-function needs.
Only if the project funds reliable hosting. Label sleeping demos clearly and provide local setup instructions so contributors are not blocked.
Do not expose production secrets to untrusted fork builds. Use restricted preview credentials or disable privileged integrations for external contributions.
