Baseline 2026 gives PWA developers a clearer support budget
A practical rubric for deciding which APIs to rely on when targeting installable web apps in 2026.
Why Baseline matters for OpenPWA quality
Baseline defines the set of web features that are interoperable across browsers. For PWAs that users install, relying on Baseline features reduces runtime surprises and improves trust after installation.
2026 Baseline checklist for PWA developers
- Use only Baseline 2026 features for core install and offline flows
- Flag non-Baseline APIs with clear fallback UI in your app
- Update manifest and service worker code to match Baseline support matrix
- Test install prompts and update flows on all Baseline-supported browsers
- Document API support levels in your OpenPWA marketplace listing
Source-backed guidance
web.dev Baseline documentation states that developers should treat Baseline as the minimum support budget for production web apps, including PWAs distributed through directories and app stores.
