Nordstjernen Browser version 1.0.8 released Read the announcement release-1-0-8.html · More info here https://github.com/nordstjernen-web/nordstjernen/releases/tag/1.0.8 . HTML Standard. Behaviour is measured against the spec text, section by section, not against another browser — 123 spec rows fully implemented, 48 partial, 4 absent as of June 2026. See docs/HTML-compatibility.md https://github.com/nordstjernen-web/nordstjernen/blob/main/docs/HTML-compatibility.md . Secure. Process-per-tab design — each tab runs in its own sandboxed renderer process seccomp + Landlock on Linux , talking to the UI over IPC and shared-memory framebuffers · no JIT. Minimalism. The whole engine is about 109,000 lines of C written by Claude and Codex 117 files in src/ , excluding the vendored libraries — small enough for one person to read and audit end-to-end. Nordstjernen has no JIT so it is much more secure, and can still be fast enough. It ships no telemetry of any kind. news - · Nordstjernen 1.0.8 released — a maintenance release.
