[Free] Client community — SSO-authenticated community community inside your WHMCS client area

[K n K Web Services]

Hi all,

Just published our Free Client community addon module to the WHMCS Marketplace — it's free, and I wanted to share the details in case it's useful to anyone dealing with repeat support tickets.

What it does:
Client community embeds a fully SSO-authenticated community community directly inside your WHMCS client area. Clients authenticate through their existing WHMCS session — no separate registration, no separate user database, no duplicate accounts to keep in sync.

Why we built it:
The same handful of questions kept showing up in our own ticket queue every week from different clients who had no idea someone else had already asked (and been answered). A standalone community platform couldn't plug into WHMCS accounts natively, so we built one that does.

Features (free version):

• Full SSO — authenticates against existing WHMCS client sessions, zero separate login
• Categories → boards → threads → replies structure
• Product-gated boards — restrict specific boards to clients with a matching product/service, useful for VIP or product-specific support areas
• Full admin panel — category/board CRUD, moderation tools, and the ability for admins to post threads directly on a client's behalf
• Markdown/rich-text editor for post bodies
• Best-answer marking and points/karma system
• Ticket-to-thread promotion — convert an existing support ticket into a public community thread in a couple of clicks
• Leaderboards
• Real full-text search (MySQL FULLTEXT with MATCH/AGAINST, not a basic LIKE query)
• Slack/Discord webhook notifications on new threads and ticket promotions
• Staff badges, rate limiting, CSRF protection, output sanitization
• English + Spanish language support out of the box
• Users can edit their own posts (including the thread title on the opening post)

Everything on that list is in the free build — nothing crippled or paywalled. There's a separate Pro tier for teams that want more (spam/profanity filtering, scheduled announcements, admin audit logs, reactions, canned responses, and a few other things in the pipeline), but the free version is a complete, usable community on its own.

Happy to answer technical questions here if anyone's evaluating it — the SSO handshake and product-gating logic in particular seem to be what people ask about most. Feedback and feature requests welcome too.
