AI low-code showdown: Which tool is fastest?

July 29, 2025

As investor scrutiny intensifies and funding windows narrow, delivering a clickable MVP quickly is essential in FinTech development. AI-powered low-code platforms promise to cut development time from weeks to hours, offering teams a crucial advantage. To test these claims, custom software company Symfa evaluated four top platforms: Marblism, Vercel’s v0, Bolt.new, and Glide.

Symfa built a functional prototype of Modelist, a debt-financing app, on each platform. The app included borrower and investor portals, payment flows, document handling, dashboards, two-factor authentication, and a mobile-first UI. Development prompts were created from real client calls, transcribed with Whisper, summarised by GPT-4o, and applied consistently across all tools.

How Symfa tested

A consistent testing process ensured fairness. Real client conversations were transcribed and summarised into prompts reflecting typical FinTech MVP needs. Each platform was tested using these prompts and evaluated on build time, manual effort, UI quality, and feature coverage. Developer usability, non-technical user friendliness, and code portability were also assessed.

Platforms at a glance

Marblism: Fast, full-stack app builds, but sometimes with complex code.
v0 (Vercel): Smooth Figma-to-code workflow but needs backend support.
Bolt.new: Offers full developer control and backend logic, but steeper learning curve.
Glide: Very user-friendly but lacks depth for real FinTech apps.

Tool-by-tool insights

Marblism excels in rapid MVP scaffolding but lacks built-in security.
v0 delivers polished front-ends starting from Figma but requires services like Supabase for backend.
Bolt.new suits developers needing backend integration and live AI edits.
Glide is best for business users prototyping simple internal tools only.

How to choose the right tool

If speed is critical, Marblism offers the fastest full-stack output; v0 is best for design-led frontends; Bolt.new fits teams needing backend flexibility; Glide works only for low-risk internal apps. For production FinTech, compliance and maintainability matter—Marblism and Bolt.new scale well with developer oversight, v0 requires backend pairing, and Glide isn’t suitable for regulated environments.
