Replyroom · Live chat
Live chat for any number of companies: a chat button for each company's site and a shared inbox for its team.
Walkthrough: a customer writes from a company's website and the team answers from the inbox, live, side by side
1 / 6
What Replyroom runs
- Any number of companies, each with its own team, customers, settings and widget, kept apart in every query
- A chat button for any site (one script tag), in the company's colour, button label and greeting
- A shared inbox: Open, Mine, Unhandled, Resolved; handled by, hand over, private notes, saved replies
- Live both ways: new messages, typing, Delivered and Seen, who's online, by server-sent events
- Files by drag, drop or paste, with a viewer; edit and delete your own messages; quotes
- Replies emailed to customers with a link back to the chat, and answers by email filed into the thread
- Platform
- Web; the widget is full screen on phones
- Best for
- SaaS, shops and agencies answering customers
- User roles
- Owner, admin, agent; customers need no account
- Database
- PGlite or any Postgres

Features
Grouped by where the work happens.
Companies and teams
4- Sign-up creates a company; one person can work for several and switch between them
- Owners and admins add teammates by email, change roles and deactivate people who leave
- Every table carries the company and every query names it: no company sees another's data
- Per-company colour, support name, greeting, button label, saved replies and email settings
The widget
5- One script tag on any site; an iframe sized to the button, the greeting or the open chat
- A form for visitors (name, and email if you want it); signed-in customers of your app skip it
- Replies, edits, deletes, attachments by picking, dragging or pasting, with a viewer
- Online / Away, staff typing, Delivered and Seen, End conversation with a star rating
- A hosted chat page per company, and a live preview beside your inbox
The inbox
5- Open, Mine, Unhandled and Resolved with counts, search, previews and online dots
- The first reply assigns; handover lines in the thread and the full handler history
- Hand over every conversation of someone leaving in one go
- Private notes customers never see, and a reply can't quote one
- Saved replies on /, with {name}; start a conversation with a customer by email
Email and security
4- Each staff reply emailed with a link that signs the customer back in
- Reply by email: a signed address per conversation; answers land in the thread
- Conversations started by email open only for verified customers
- Files served only through routes that check the reader; rate limits in Postgres

Common questions
01. Can several companies use one installation?
Yes. Every company is a separate workspace with its own team, customers, conversations, saved replies and widget. Every query is scoped to the company, and a person can belong to several companies and switch between them.
02. Does it need Supabase or Vercel Blob?
No. It runs on PGlite (nothing to install) or any Postgres, keeps files on disk, and sends realtime by server-sent events. Vercel Blob is supported for serverless hosts, where the disk doesn't last.
03. How do customers sign in to the chat?
Visitors give a name (and an email if the company asks). If customers sign in to the company's own app, it passes who they are, signed with the company's widget secret, and they skip the form. Anyone who opens the link in a reply email is signed in too.
04. Is it really live?
Yes: new messages, typing, Delivered and Seen, and who's online arrive within a moment through server-sent events, across server instances via Postgres LISTEN / NOTIFY. Polling stays on as a safety net.
05. Can customers answer by email?
Yes, with an inbound email provider (Resend Inbound, Postmark, SendGrid, Mailgun). Every reply email has a signed address for its conversation, and only the conversation's customers can post through it.
