How fast can you ship an MVP?

21 calendar days from kickoff to production deploy on the 21-Day MVP path. Custom Software builds run 6 to 26 weeks depending on scope.

How much does an MVP cost?

21-Day MVP from $5,000 USD. Custom Software Development from $11,000. AI Development from $7,000. Final quote depends on scope and integration count.

What stack do you use?

Default stack: Next.js, TypeScript, Node.js, Python, PostgreSQL, AWS, Stripe, Clerk, OpenAI, Anthropic Claude.

What services does Parallel Loop offer?

Three service lines: 21-Day MVP Development (from $5,000), Custom Software Development (from $11,000), and AI Development and AI Agents (from $7,000). Within these, 11 specialised service pillars including mobile app development, ecommerce, automation, CRM integration, cloud DevOps, and enterprise solutions.

How is the 21-Day MVP different from Custom Software?

The 21-Day MVP is productised with fixed scope, fixed price, and fixed 21-day timeline. It fits single-workflow products with off-the-shelf integrations. Custom Software is bespoke, sprint-based, and runs 6 to 26 weeks for products with multiple workflows, regulated scope, or enterprise integrations.

What stacks do you support?

Default stack: Next.js, TypeScript, Node.js, Python, PostgreSQL, AWS, Stripe, Clerk, OpenAI, Anthropic Claude. We can work in Java, .NET, Go, Ruby, PHP, Swift, Kotlin where the existing landscape requires it.

Do you offer AI development separately?

Yes. AI Development and AI Agents is a separate service line covering chatbots, generative AI, machine learning, computer vision, NLP, and AI consultation. From $7,000 for a chatbot MVP up to $35,000+ for a custom AI platform.

What is included in pricing?

Working software, full source code, CI/CD pipeline, staging plus production environments, runbook, monitoring setup, dual on-call cover for 2 weeks post-launch. We do not charge separately for architecture, design, or QA. They are part of every engagement.

Can you handle compliance and security?

Yes. We build HIPAA, PCI DSS, SOC 2 Type II, GDPR, ISO 27001, NERC CIP, IEC 62443 architecture where the build requires it. We do not issue audit certificates. We build the architecture and evidence collection that supports your audit firm.

Do you offer maintenance after launch?

Yes. Maintenance retainer from $2,200 per month. On-call cover, dependency upgrades, small features, security patching. SLA-backed. We do not require a retainer to do a build; we offer it as an option.

How fast can you start?

Typically 2 to 4 weeks from scoping call to kickoff. We do not double-book the team.

What is the average engagement length?

21-Day MVP: 21 calendar days. Custom Software: 6 to 26 weeks. AI Development: 4 to 20 weeks. Maintenance retainers run month to month.

How do I know which service line fits?

Book the free 45-minute scoping call. 30 minutes on your build, 15 minutes on which path fits. We tell you at the call if your build does not fit our service lines.

Is FlutterFlow a real product or a toy?

It is a real product used in production by thousands of teams. It is not the right tool for every app, but it is the right tool for many MVPs, internal tools, and consumer apps with bounded complexity. The low-code lock-in problem is solved because FlutterFlow exports clean Flutter code.

When should I use FlutterFlow vs custom Flutter?

FlutterFlow when speed and lower cost matter more than complete control. Custom Flutter when the app has complex animations, custom-rendering UI, deep platform integration, or you need to optimise the underlying architecture. We pick at scoping based on your scope and your team.

Can I migrate from FlutterFlow to custom Flutter?

Yes. FlutterFlow exports the Flutter codebase. We have done this migration multiple times. Typical migration cost is 40 to 60 percent of a greenfield Flutter build because the design system, screens, and business logic are already there.

Does FlutterFlow support backend other than Firebase?

Yes. Supabase, custom REST APIs, GraphQL APIs all supported. Firebase is the default and fastest path but not required.

Can FlutterFlow handle payments?

Yes. Stripe integration native. RevenueCat for subscriptions. In-app purchases via StoreKit and Play Billing through custom code. Apple Pay and Google Pay via Stripe Mobile SDK.

Does it submit to the App Store and Play Store?

Yes. FlutterFlow exports a real Flutter app that submits to both stores like any other Flutter app. We handle the submission and review feedback as part of the engagement.

Will my team be able to edit the app afterwards?

Yes. FlutterFlow project hand-over means your team can keep editing visually. We also hand over the exported Flutter codebase so a developer can edit the underlying code if needed. No lock-in either way.

How we work

Overview: Three phases from FlutterFlow project init to both stores live. We hand over the FlutterFlow project plus the exportable Flutter codebase so you are not locked in.
Step 1 — Scope and architecture: One-week scoping. Screens mapped in Figma. Data source decisions (Firebase, Supabase, custom REST or GraphQL API). FlutterFlow project initialised with your branding and theme.
Step 2 — Build in sprints: 3 to 7 weeks build. Visual building in FlutterFlow. Custom code where the visual builder cannot reach (custom widgets, custom actions, complex animations). Weekly Tuesday demo with live FlutterFlow preview.
Step 3 — Harden and launch: 1 to 2 weeks hardening plus dual store submission. Export native Flutter code for review. App Store and Play Store submission. FlutterFlow project handover plus exported codebase delivered to you.

What we deliver. FlutterFlow

Visual app build in FlutterFlow

Screens, components, navigation, theming, animations all built visually. Custom widgets where the FlutterFlow library is missing pieces. Custom actions for business logic.

Backend integration

Firebase (Auth, Firestore, Cloud Functions, Storage) as the default fast path. Supabase for Postgres-backed builds. Custom REST or GraphQL API for builds with existing backends.

Custom code where the visual builder hits its ceiling

Custom Flutter widgets, custom actions in Dart, custom functions for FlutterFlow. We do not pretend FlutterFlow does everything visually; we drop into code when it has to.

Payments, push, and platform integration

Stripe and RevenueCat for payments via FlutterFlow integrations or custom code. Firebase Cloud Messaging for push. Deep linking. Sign in with Apple, Google, and email magic link.

Web plus mobile from one project

FlutterFlow exports to iOS, Android, and web from the same project. Common pattern: launch web first for SEO, then ship mobile. Or ship all three simultaneously.

Exportable Flutter codebase

FlutterFlow exports clean Flutter code at any time. We hand over both the FlutterFlow project AND the exported code so your team can take it native if the product outgrows FlutterFlow.
