The Best No-Code and Low-Code App Builders for UK Small Businesses (2025 Guide)

If you’re exploring ways to build custom apps for your business without the expense of your own software development team, this guide is for you. We’ve rounded up the best no-code and low-code app builders available to UK small and medium-sized businesses, explained when to use each, and included evidence from independent sources to help you choose with confidence.

Why I did this research

With new AI tools emerging almost daily in my inbox and news feed, I wanted to take a step back and look at where the UK market really stands for no-code and low-code software development. As a small business owner myself, I’m constantly assessing which technologies deserve our focus – especially as these tools are reshaping how software is created and delivered.

One thing is clear: AI is here to stay, and it’s transforming the way businesses build custom software. The combination of AI-driven automation and accessible, low-code platforms means that creating bespoke business apps is now faster and more achievable than ever.

Since software development sits at the heart of what we do at AlphaFirst, staying ahead of this shift isn’t optional – it’s essential. This research helps us (and our clients) understand where the opportunities lie, which no-code development software tools are leading the way, and how we can harness them to deliver smarter, faster, and more cost-effective solutions.

Why No-Code Development Software Is Exploding Among SMEs

The demand for no-code development software is rising fast.

According to Grand View Research, the UK low-code application development platform market was worth over $1.1 billion in 2023 (over £800 million at time of writing) and continues to grow strongly each year.

With over 5.5 million SMEs in the UK, many businesses are turning to no-code and low-code tools to automate processes, replace spreadsheets, and build customer-facing apps—without the cost of a large IT team.

Put simply: no-code and low-code app builders let your staff create digital tools that used to require developers. Whether you’re tracking stock, managing orders, or building client portals, there’s now a platform designed for you.

The Top No-Code Development Software for UK Businesses

Below we’ve listed the best no-code and low-code app builders that are popular with UK small and mid-sized companies. These are proven, affordable, and supported by strong ecosystems—so you can get started quickly and scale with confidence.

1. Microsoft Power Apps (Power Platform)

Best for: Companies already using Microsoft 365.
Use cases: Internal tools, approval workflows, HR forms, and apps inside Teams or SharePoint.

Why it stands out:

Power Apps integrates directly with Microsoft 365, OneDrive, and Dataverse. Many UK businesses already have access to it within existing Microsoft licences. Microsoft is recognised as a Leader in Gartner’s Enterprise Low-Code Application Platform Quadrant.

Pros

  • Deep integration with Microsoft 365 and Teams
  • Large UK partner network
  • Transparent UK pricing and enterprise-grade security

Considerations: It can have a learning curve if you’re building complex apps, and storage (Dataverse) costs should be planned early.

2. Google AppSheet

Best for: Businesses using Google Workspace.
Use cases: Checklists, site inspections, data capture, stock control, and reporting dashboards.

Why it stands out:

AppSheet is part of Google Workspace and allows you to build apps directly from Sheets or Drive. It’s quick to deploy and cost-effective, starting from only a few pounds per user.

Pros

  • Seamless Google Workspace integration
  • Easy for non-technical users
  • Fast mobile deployment

Considerations: Limited for complex designs or heavy automation.

3. Airtable (with Interfaces & Automations)

Best for: Teams wanting to move beyond spreadsheets.
Use cases: CRM systems, project tracking, stock management, operations dashboards.

Why it stands out:

Airtable combines the simplicity of a spreadsheet with the structure of a database. With the addition of Interfaces and Automations, it becomes a powerful low-code platform for day-to-day business operations.

Pros

  • Visually intuitive for spreadsheet users
  • Excellent templates and integrations
  • Free tier available

Considerations: Paid plans are per-seat, and data limits can add up as usage grows.

4. Softr, Glide & Stacker

Best for: Building portals, booking systems or client dashboards.
Use cases: Customer and partner portals, delivery tracking, project updates, and HR portals.

Why they stand out:

These no-code builders connect to your Airtable or Google Sheets data and let you publish professional-looking web apps quickly—without coding or hosting headaches.

Pros

  • Incredibly fast time-to-launch
  • Templates for common SME workflows
  • Secure user logins

Considerations: Designed for lightweight business apps rather than fully custom web products.

5. Bubble

Best for: Start-ups and SMEs that need a real customer-facing web app.
Use cases: Marketplaces, membership platforms, SaaS products, or booking systems.

Why it stands out:

Bubble is one of the most powerful no-code web app builders available. It supports logic, databases, workflows, and plugins—allowing ambitious businesses to create full web apps without developers.

Pros

  • Feature-rich platform for serious projects
  • Active global community and support
  • Scalable hosting

Considerations: More complex to learn than simpler builders and usage-based pricing can increase as you scale.

6. Retool & FlutterFlow

Retool – Best for: Internal business tools where a developer is available.
FlutterFlow – Best for: Mobile-first apps for iOS, Android, and the web.

Why they stand out:

Both target slightly more technical users. Retool makes building admin dashboards or data management apps lightning-fast. FlutterFlow is ideal for those who want to launch mobile apps with native performance.

Pros

  • Retool integrates with APIs and SQL
  • FlutterFlow outputs real Flutter code for flexibility
  • Both offer free and team tiers
