Project philosophy
- Clarity first. Results stay readable, with clean source and snippet details.
- Trust through specifics. No cookies, no accounts, no analytics scripts.
- Local-first preferences. Theme and history stay on your device.
- Small and inspectable. A minimal stack keeps behavior easy to verify.
How Helios works
Meta-search
Queries are sent to multiple search providers and merged into a single list.
Voice search
Hands-free queries with built-in speech recognition when supported.
Local preferences
Theme, accent, and search history stay on your device.
Self-hostable
Run it yourself for full control over infrastructure and logs.
Technology choices
The backend runs on Deno with the standard library. The frontend is plain HTML, CSS, and JavaScript — no framework and no build step. That keeps the surface area small and the behavior easy to audit.
