Helium Browser vs SeaMonkey
Side-by-side comparison of features, pricing, ratings, and alternatives.
Helium is an open-source, Chromium-based desktop browser built by imput that strips out Google services and telemetry while keeping full compatibility with Chrome extensions. Ad, tracker, and cookie-banner blocking are on by default using community filter lists, so users get uBlock-style protection without any setup.
SeaMonkey is a free, open‑source internet suite that combines a web browser, email client, HTML editor, IRC chat client, and newsreader into a single cohesive application. It is maintained by the SeaMonkey community and follows the same standards as the classic Mozilla suite. Designed for power users who prefer an integrated environment, SeaMonkey runs on Windows, macOS, and Linux, offering cross‑platform consistency and a classic user interface that emphasizes control and customization.
