"Can we start from an existing MVP to build the full SaaS?"

Yes, that's even the recommended path. If the MVP was built on our stack (Next.js + Supabase), migration to the full SaaS is direct. Otherwise, we audit the existing code and assess what's reusable.

"Do you handle DevOps (CI/CD, monitoring)?"

Yes. GitHub Actions, Vercel, Sentry, Datadog - we configure the full infrastructure. Delivery includes an operational runbook for your team.

"Can we integrate our SaaS with third-party tools (Slack, HubSpot, Zapier)?"

Absolutely. Inbound/outbound webhooks, OAuth, documented public API - we anticipate the integration ecosystem from the initial architecture.

"What happens if we want to switch vendors after delivery?"

You have the full source code, technical documentation and a handover brief. You're only tied to Codea if you choose to be. Our interest is that you stay out of satisfaction, not dependency.

Custom SaaS development - from idea to scalable product - what it means in practice

Building a scalable SaaS requires architecture thought out from day one: multi-tenancy, Stripe subscription management, Row Level Security in the database, and analytics dashboards. Codea delivers B2B and B2C SaaS in 8 to 12 weeks on a modern stack (Next.js 15, Supabase, TypeScript) - with full source code, documentation and a skills transfer included.

“We had tried to build in-house for 6 months with no result. Codea delivered V1 in 10 weeks with an architecture we could evolve ourselves afterward. That's the definition of delivering value.”
