Detailed Review

Appsemble is a Dutch open-source low-code platform from Appsemble B.V., based in the Klokgebouw in Eindhoven. Apps are defined as human-readable YAML or JSON recipes built from reusable blocks, run as progressive web apps, and the code is published under LGPL-3.0. Because an app is a plain text definition, it can be versioned, reviewed and moved like source code, which is a different idea of portability from an export button.

Its pricing is unusually simple. Building an app on the standard blocks costs nothing. Hosting is a flat EUR 50 per app per month excluding VAT, including European cloud hosting, a standard backend and 10 GB of storage. An enterprise SLA starts at EUR 100 per app per month, and third-line support for self-hosters at EUR 40. Custom blocks and apps are quoted from EUR 1,000 and EUR 5,000.

Appsemble is small and its documentation and references are largely Dutch. It is not a rival to Mendix or Betty Blocks for large estates, and it has none of their governance tooling, but for a team that wants to avoid lock-in and know the monthly bill in advance it is one of the most transparent options in the category.

For the same reason it suits pilots, where a single app can be hosted for a known monthly cost and judged on results.

What Appsemble does well

  • Open source under LGPL-3.0, apps are portable recipes
  • Flat published price of EUR 50 per app per month
  • Hosting in the European cloud, 10 GB included per app
  • Self-hosting is supported, with third-line support from EUR 40
  • Dutch company with a visible office in Eindhoven

Where Appsemble falls short

  • Small vendor, so a smaller ecosystem than the large platforms
  • Most documentation and references are in Dutch
  • Custom blocks and apps are paid work from EUR 1,000 and EUR 5,000
  • No enterprise process or governance tooling like larger platforms

Standout feature. A flat EUR 50 per app per month with European hosting and an open-source licence, which is rare for a low-code platform.
