We're paying monthly for a forum we don't control and can't theme. Is self-hosting Forum V1 a big lift on shared hosting?
The forum you own, end to end.
Forum V1 gives you the depth of classic forums, the polish of modern community apps, and the ownership a hosted platform can never offer. A hardened, framework-free PHP application you install on your own server — and keep.
Migrating off a hosted platform — worth it?
Not at all. Drop the files on any PHP 8.2 host with MySQL, run the installer, done. No Composer, nothing phoning home. Roles, themes, DMs and moderation are all built in — and the data is yours to export anytime.
A complete community, not a starter kit.
Forum V1 ships the full forum: discussion, moderation, member identity, and operator control — knowledge-first by design, never a chat app in disguise.
Forums, topics & answers
Categories and forums in a clear hierarchy. Markdown topics with preview, polls, reactions, and a proper question-and-solution flow.
Profiles & reputation
Avatars, presence and last-seen, reputation and contribution signals, bookmarks, follows, unread state, and catch-up.
Private & group conversations
Direct messages and group PMs built in, with an admin inspection policy for trust and safety.
ACP & MCP
A full Admin Control Panel and a separate Moderation Control Panel. Roles, capability-based permissions, and owner control throughout.
Themes & plugins
The Arrivao Atlas theme system with packaged themes, CSS and template overrides, plus a local trusted plugin manager with ZIP upload.
Search & discovery
Search and suggestions as a V1 requirement, with discovery widgets and a discovery page — tuned for knowledge, not doomscrolling.
Hardened, not hopeful.
The security work is the standout of the codebase audit, not a footnote. Forum V1 was built with authorization, upload safety, and request isolation treated as first-class concerns across nine phases.
Per-request permission isolation
A fresh REQUEST_ID rotates the permission-cache namespace on every request, preventing cross-request authorization leakage — with a regression test guarding it.
Theme upload hardening
The theme ZIP validator rejects any .php file or templates/ directory in uploads, verifies preview images as genuine PNG/JPEG, and sanitises free-text CSS.
Plugin manifest validation
Plugin IDs are validated against stream-wrapper injection, so a malicious manifest can't smuggle a path where it shouldn't go.
Capability-based permissions
Access is granted by capability, not by hardcoded role checks scattered through the code — auditable, and safe to extend.
Free to start. Yours either way.
Open-core, not a locked licence. A real free self-hosted edition seeds the ecosystem; paid tiers add themes, modules, and support.
Core forums, ACP/MCP, private messages, basic themes, and plugin support. Real, but focused.
More themes, friendlier setup, optional discovery and gamification presets, hardened plugin management.
The full module set: premium themes, advanced diagnostics, support desk, and update priority.
We host it: updates, backups, monitoring, SSL and domain help, mail and cron handled for you.
Live in a few minutes.
Forum V1 is a standalone PHP application — it runs on its own, not as a WordPress plugin. Put it on a subdomain or subfolder beside your existing site.
community subdomain.# 1 · place the app on your host community.yourdomain.com → /forum-v1 # 2 · empty database, ready to fill db: forum_v1 user: forum_user # 3 · open the installer https://community.yourdomain.com/install # ✓ schema built · admin created · live
Forum V1 lives alongside WordPress, not inside it. Run it on a subdomain like community.yourdomain.com (or a subfolder) and link to it from your menu. Your WordPress site and your forum stay cleanly separated, each on its own stack.
Own your community from day one.
