Customer support, in one inbox.
Embed a contact widget in minutes. Triage submissions from sales, support, security, and abuse requests in a single unified admin. Built for teams that ship.
Everything you need to stop juggling tools.
One inbox for every channel
Sales leads, support tickets, security disclosures, GDPR requests — all in one timeline, scoped per workspace.
Embeddable widget
Drop a single <script> tag on any page. Customers reach you where they already are. 4 KB gzipped, no framework lock-in.
Public + secret API keys
Stripe-style keys with origin allowlists for browser widgets and bearer auth for server-side submissions. Rotate any time.
Infra-aware triage
For NimbusNexus customers, every ticket auto-attaches the user’s account state — VMs, billing, recent orders — so agents triage with context, not guesswork.
Email two-way threading
Staff replies email the customer; their response lands back in the timeline as a customer message. Message-ID + In-Reply-To threading, no app to install for the end user.
Multi-tenant from day one
One backend, many workspaces. Spin up isolated inboxes for each customer, environment, or team. Invite collaborators by role.
Submit on the left. Triage on the right.
The widget your visitors use, next to the inbox your team works from. Send the form and your message lands in the agent’s inbox — open it to see the submitter’s email, the full message, and reply right there (replies go back by email). The real, network-connected widget is also live in the corner of this page.
Interactive preview — click a ticket to open it. Nothing here is actually sent.
