Empowering modern agencies to deliver client work without chaos.
Selpx is the ultra-fast, white-label client portal built for freelancers, design studios, and software boutiques who want clean client collaboration without clunky enterprise bloat.
Our Mission
Traditional client portals like SuiteDash or Copilot are often overloaded with hundreds of configuration menus, confusing onboarding paths, and sluggish loading speeds. Modern agencies and independent consultants need something different: a portal that takes less than 5 minutes to launch, loads in under 100 milliseconds, and makes their brand look world-class.
Engineered by Nixpx, Selpx was created to unite client communications, document approvals, Stripe invoicing, and project deliverables into one frictionless hub branded entirely under your domain.
Sub-100ms Speed
Built on modern web edge standards so clients and team members never wait for screens to load or sync.
100% White-Label
Your custom domain, your logo, your colors, and your brand voice. No distracting vendor badges.
Client-Side Privacy
Our free generator tools run securely in the browser, keeping your budgets and client data private.
Commitment to the Freelance Community
We believe great business software should be accessible. That is why we built and maintain 14 free productivity tools for freelancers and agencies around the world, from our Free Invoice Generator to our Freelance Rate Calculator and Proposal Builder.
