Yes, for the right shape of app. We build the frontend in Webflow and connect it to backends like Xano, Firebase, or Supabase. Past a certain complexity, a custom Next.js frontend serves you better — we will tell you which on the strategy call.
We bundle and defer scripts, use the Webflow asset pipeline properly, and benchmark against Lighthouse on every release. Custom code does not have to mean slow sites.
Yes. Custom code is layered on without breaking the Webflow Designer, so non-technical editors keep full content control.
Most focused engagements ship in 4–10 weeks. Smaller sprints (audits, integrations, prototypes) run 1–2 weeks. We give you a milestone-based timeline before kickoff so you can plan around it.
Sprints start from US$3,500, fixed-scope MVPs from US$12,000, and embedded engineering from US$8,000 per senior engineer per month. Full breakdown on our How We Work page.
You do, from day one. All deliverables and IP transfer to you on each milestone, documented in the engagement agreement. There is no lock-in and no ongoing license fees on the code we write.
We handle change in writing. Small adjustments are absorbed; larger changes get a quick change order with revised scope and price so there are no surprise invoices.
