8 Best Low-Code Platforms in 2026, Compared on Pricing Models

The best low-code platforms in 2026 are OutSystems and Mendix for enterprise core systems built by professional developers, Appian for process-heavy workflow automation, Microsoft Power Apps for companies already on Microsoft 365, Google AppSheet for Google Workspace companies, Quickbase for operations teams, and Retool for developer-built internal tools. The bigger difference between them is how they charge: by application size, by app, by user or by builder. Pick the pricing model that matches how your apps will be used, then the feature list. If you need one specific app rather than a platform, an AI app builder like Greta.sh generates it from a description. Prices below are as of October 2026.

Low-code platforms sell speed. What they also sell, less loudly, is a long contract on a proprietary runtime. That second part deserves as much scrutiny as the demo.

How we compared

Four questions decided the ranking: who is expected to build (professional developers, citizen developers or both), how the platform charges, whether you can try it for free without a sales call, and how hard it is to leave. Prices and plan details were checked on each vendor's own pricing page on October 4, 2026, and are stated as of October 2026 in the currency and billing basis each vendor uses. Several enterprise platforms publish no prices at all; we say so rather than guess.

At a glance

The 8 best low-code platforms

1. OutSystems – enterprise apps for professional developers

OutSystems is built for IT teams delivering customer-facing portals and core systems, and now pitches itself as an agentic systems platform for apps and AI agents. Pricing is by custom quote. The pricing page explains the meter: the size and complexity of your apps, measured in Application Objects (the sum of screens, database tables and API methods, with a typical medium-sized app at about 150 AOs), the number of internal and external end users (counted separately), and add-ons such as extra runtimes, 24x7 support or higher uptime. The paid platform starts with 100 internal users. A free Personal Edition lets you learn the platform on your own.

Who it's for: organizations with a development team and apps that must run for years. Limits: no public price, and the AO meter means a growing app portfolio grows the bill.

2. Mendix – from one app to a portfolio

Mendix publishes entry prices in euros. Free is €0. Standard starts at €918 a month for one app or €2,295 a month for unlimited apps, and Mendix notes there's no technical difference in platform capabilities between those two options. Premium, for mission-critical systems with horizontal scaling and high availability, is quote-only.

Who it's for: teams that want a published starting price and a path from a first department app to many. Limits: the pricing table lists hosting (Mendix Cloud, Azure, Kubernetes, SAP BTP or your own servers) as an additional cost on Standard and Premium, so the entry price isn't the full bill.

3. Appian – process automation first

Appian is strongest where the "app" is really a process: case management, approvals, document-heavy workflows. Its pricing page lists Standard, Advanced and Premium tiers, each "priced per user, per month, per app," without publishing numbers. A free Community Edition gives you a personal development environment to explore the platform.

Who it's for: regulated, process-heavy organizations. Limits: per-app pricing adds up when you want many small apps, and you'll need a sales conversation for any number.

4. Microsoft Power Apps – the default inside Microsoft 365

Power Apps is the obvious choice when identity, files and data already live in Microsoft 365 and Dataverse. The Developer Plan is free for building and testing. Power Apps Premium is $20.00 per user per month, paid yearly ($12.00 with a 2,000-seat minimum), with a Dataverse entitlement of 250 MB of database and 2 GB of file storage; extra database capacity is $40.00 per GB per month, paid yearly. Microsoft's FAQ is clear that building is free and running apps needs paid licences.

Who it's for: Microsoft shops with clearly defined app users. Limits: every end user needs a licence, which is why so many teams go looking for Power Apps alternatives.

5. Google AppSheet – the Workspace counterpart

AppSheet builds apps over Sheets, Drive and other data sources. You can build and test with up to 10 users at no cost. Starter is $5, Core $10 and Enterprise Plus $20 per user per month, and Google says Core is included in most paid Google Workspace plans. Enterprise Plus adds connections to cloud databases, APIs and enterprise data services.

Who it's for: Google Workspace organizations, especially where Core is already paid for. Limits: per-user pricing again, and the deepest data connections sit on the top plan.

6. Quickbase – operations teams that live in data

Quickbase targets operations teams building databases, workflows and reports without developers. Team starts at $35 per user per month and Business at $55 per user per month, both priced annually, and Quickbase states the cost shown does not include a platform minimum. All users must be on the same plan. There's a 30-day free trial with Business plan features.

Who it's for: ops-heavy teams replacing spreadsheet sprawl. Limits: the undisclosed platform minimum means the per-user figure isn't the whole bill.

7. Retool – internal tools for developers

Retool is low-code for people who can write SQL and JavaScript. Free covers up to 5 users. Team is $10 per builder and $5 per internal user per month, and Business $50 per builder and $15 per internal user per month, both billed annually; Business adds portals and embedded apps for external users.

Who it's for: engineering teams who want admin panels and dashboards without building UI from scratch. Limits: non-developers will struggle. Our internal tool builders roundup compares Retool with its closest rivals.

8. Greta.sh – the AI-first route to one custom app

Greta.sh isn't a low-code platform in the drag-and-drop sense. You describe the app in plain English and it generates a full-stack application (frontend, backend, database, authentication), with code you can export as Next.js. Pricing: Free is 5 credits a day; Starter is $5 a month on the welcome offer (normally $20 a month) and adds deployment and custom domains; Pro is $20 a month on the welcome offer (normally $50 a month) and adds the Database feature, GitHub version control and team management; Business is $200 a month; Enterprise adds SSO and SLA guarantees.

Who it's for: founders and teams who need one or two specific apps and would rather own the code than license a platform. Limits: no enterprise governance layer like OutSystems or Mendix, and no prebuilt ERP connectors. You maintain what you ship.

Pricing models decide more than features

Every platform here can build a form, a table and an approval step. What differs is what you pay as you grow:

• Per end user (Power Apps, AppSheet, Quickbase): cheap for a small, defined audience; expensive when a whole company opens the app.
• Per builder plus cheaper viewers (Retool): good when a few people build for many.
• Per app (Appian, Mendix one-app): good for one important app, painful for twenty small ones.
• By application size (OutSystems): tracks the complexity of what you build, not who uses it.

Model your next two years of apps and users against each before you sign. The vendor lock-in checklist covers the other half of the decision: what you can take with you if you leave.

Low-code, no-code or AI app builder?

Low-code platforms assume someone technical will configure logic and integrations, and they wrap that work in governance. No-code tools trade depth for speed for non-technical builders. AI app builders generate the app itself from a description. Our comparison of no-code app builders and AI app builders goes deeper on that split. And if most of your "apps" are really data collection, look at the best online form builders first; a form tool is far cheaper than a platform.

Frequently asked questions

What is the best low-code platform?

For enterprise systems built by professional developers, OutSystems or Mendix. For process automation, Appian. For Microsoft 365 organizations, Power Apps, and for Google Workspace organizations, AppSheet. For developer-built internal tools, Retool. The right one depends mostly on who builds and how the platform charges.

Which low-code platforms publish their prices?

Of the platforms here, Mendix (Standard from €918 a month), Power Apps, AppSheet, Quickbase (before its platform minimum) and Retool publish prices. OutSystems and Appian quote on request, though both offer a free edition for learning.

Is there a free low-code platform?

Several have free editions with limits: the OutSystems Personal Edition, Mendix Free, the Appian Community Edition, the Power Apps Developer Plan (building and testing only), AppSheet for up to 10 test users, and Retool for up to 5 users.

What is the difference between low-code and no-code?

Low-code platforms expect some technical configuration (logic, queries, integrations) and are aimed at developers or technical business users. No-code tools aim at non-technical builders and trade depth for ease of use.

Is low-code cheaper than custom development?

Often for the first app, not always over time. Per-user, per-app and size-based pricing all grow with adoption, while custom code you own costs hosting and maintenance instead. Model both over two years before deciding.

Choose the meter, then the platform

Shortlist two platforms whose pricing model fits your usage, build the same small app on both during the free tier or trial, and compare the quote you'd get at your real user count. The feature gap between leaders is small; the bill gap is not.
