Why OpenDuomo
What you get when you build with us
We don't just write code — we build software that runs everywhere, stays maintainable, and comes with a team that's still around when you need to evolve it. Here's what that looks like in practice.
PWA-First by Default
Every product we build can be a Progressive Web App out of the box — installable on any device, available offline, and updated instantly without app-store delays. Your users get a native-quality experience; you skip the $99/year Apple tax.
One Codebase, Every Platform
A single PWA reaches iOS, Android, and desktop browsers simultaneously. No maintaining separate native apps, no duplicated feature work — just one clean codebase that ships faster and costs less to evolve.
Built to Grow With You
We write software with the next phase already in mind — clean architecture, sensible patterns, and a codebase your team can actually hand off, extend, or revisit six months down the line without headaches.
Rapid Prototype → Production Pipeline
Already have a Cursor, v0, or Claude-generated prototype? We clean it up, add the infrastructure it needs, and take it to production — often in weeks, not months. No big-bang rewrites required.
No App Store Lock-In
PWAs ship directly from your domain. Push critical updates the moment they are ready, A/B test freely, and own your distribution channel. You are never one App Store policy change away from losing your users.
A Long-Term Engineering Partner
We stay engaged after launch — monitoring, iterating, and scaling with you as your needs evolve. Think of us as a senior engineering team on call, not a vendor who disappears after delivery.
Our Capabilities
What we ship for our clients
From day one to post-launch, here are the capabilities we bring to every engagement.
Authentication & User Management
Secure sign-up, login, and role-based access control built in from the start — not bolted on later. SSO, magic links, and session handling handled properly.
Database Design & Integration
Relational or document-based, we design schemas that scale. Postgres, Supabase, PlanetScale, or whatever fits your stack — integrated cleanly with your application logic.
Push Notifications
Native-quality push alerts delivered through your PWA — no native app required. Re-engage users with timely, permission-based notifications on iOS, Android, and desktop.
Third-Party API Integrations
Stripe for payments, Twilio for SMS, Google Maps, Zapier, and beyond. We connect your app to the services your business already depends on — reliably and securely.
Admin Dashboards & Internal Tools
Custom back-office interfaces your team will actually want to use. Data tables, reporting views, content management, and operational controls — purpose-built for how you work.
Real-Time Features
Live feeds, collaborative editing, instant notifications, and synced data across sessions — powered by WebSockets or server-sent events, depending on what your product needs.
