SignlOS vs FeatureOS
FeatureOS (formerly Hellonext) is a capable all-in-one feedback suite that even includes a knowledge base. The honest difference: SignlOS trades the docs module for built-in status pages and Kanban projects, and keeps self-serve pricing to two flat plans — $0 Free and $29/mo Pro (unlimited teammates on Pro).

The case for SignlOS
Why teams switch
Simple, flat pricing
SignlOS has two self-serve plans — Free ($0, one board, 3 teammates) and Pro ($29/mo or $290/yr, unlimited teammates) — plus custom Enterprise agreements. No tier-shopping across long feature checklists.
Status pages and incidents included
Beyond boards, roadmap, and changelog, SignlOS ships public status pages with incident tracking and custom domains — the whole ship-and-communicate loop in one workspace.
Passwordless and passkey sign-in
Email or SMS one-time codes plus passkeys (Touch ID / Face ID) mean your users never manage a password just to upvote a feature.
Your data stays portable
Everything in SignlOS is reachable through a versioned REST API with API keys, so your feedback data can be exported any time — no lock-in.
