Big-city chamber software. Small-town charm & budget.
Built for the volunteers, board members, and part-time directors who run America's Main Street chambers of commerce — the same directory, events, dues, deals, and AI tools the big metro chambers use, at a price a 20-member chamber can actually afford.
Volunteer-run? Perfect — that's exactly who we built this for.
One plan · $29.99/mo (or save 25% annual) · Non-profit-friendly · Live in an afternoon
You run a chamber
You're in the right place.
ChamberOS is the platform for your chamber organization — your public website, directory, events, dues, and member portal. Sign your chamber up here.
You own a local business
You join through your chamber.
Local businesses don't sign up directly with ChamberOS — your local chamber of commerce invites you onto their site. We can show you how.
Everything the big chambers have
One platform. Every chamber workflow.
Small-town chambers shouldn't have to stitch together a website, a spreadsheet, Eventbrite, PayPal, and a Facebook group. ChamberOS bundles it all — and a volunteer board can run it, because it runs itself.

Your chamber site practically runs itself — all day, every day.
Close your laptop. ChamberOS keeps answering questions, signing up members, selling event tickets, and welcoming visitors at 2pm on a Tuesday and 2am on a Sunday. You wake up to a tidy inbox of what happened — not a pile of work to do.
Answers visitors 24/7
The AI concierge handles hours, member lookups, event questions, and contact info — even at midnight.
Signs up new members
Self-serve join flow with dues, tiers, and auto-renewals. New members are live the moment they pay.
Sells event tickets
RSVPs, paid tickets, and confirmations go out automatically — no one waiting on you to reply.
Collects dues on autopilot
Annual renewals, receipts, and reminders run themselves. Non-profit payment handling included.
The result: a small team of volunteers runs a full-time chamber — without burning out.
Site templates
Pick a look. Make it yours. Ship today.
Every chamber starts with a curated template — no design work required. Switch templates anytime from your admin console; your members, events, and content stay put.
Visual Grande
Photographic · Full-bleed · Overlay cards
A large photographic hero fills the screen with three configurable quick-link cards (Directory, Events, Community) floating over it — inspired by classic small-town chamber sites.
Civic Classic
Photographic · Navy & brass · Established
Photo-led hero, member highlights, upcoming events. The default look — perfect for established chambers that want a confident, traditional feel.
Main Street
Editorial · Serif · Warm
Big serif headlines, magazine-style sections, calm whitespace. Great for small towns and main-street districts that want personality.
Heritage
Archival · Editorial · Story-driven
Masthead-style header, pull-quotes from the archives, divider-lined stats. Best for chambers with a deep history to tell — depot towns, county seats, founding families.
Plainspoken
Minimal · High-contrast · Honest
Big bold type, hard rules between sections, almost no chrome. Perfect for volunteer-run chambers that want a site that just says what it is.
Modern Civic
Minimal · Bento · Contemporary
Asymmetric hero with a bento grid of features, tight stats strip, condensed CTAs. For chambers projecting a modern, tech-forward identity.

The short answers.
Is this for chambers or for businesses?
ChamberOS is for chamber of commerce organizations. Local businesses don't sign up directly — they join through their chamber's site after the chamber is live on ChamberOS.
What if our chamber is all volunteer?
Perfect — that's exactly who we built this for. Most of ChamberOS runs itself so a volunteer board can keep up without burning out.
Do members pay you?
No. Member dues flow directly to your chamber's own payment account. You charge what you want, on the tiers you want.
Do you work with very small chambers?
Yes — Main Street is built for chambers as small as 10 members.
Is ChamberOS a non-profit-friendly platform?
Yes. Pricing, payment processing, and receipts are configured for 501(c)(6) chambers.
Can we use our own domain?
Yes — custom domains and SSL are included in every Main Street plan.
How long does setup take?
Most chambers are live in a single afternoon. We'll help you import members.
Who owns the data?
You do. Export anytime in standard formats.
Your Main Street deserves big-city tools.
