Enterprise low-code platform priced by application complexity units, not just users

The short version
- Only Backendless has a free tier, so it costs nothing to try first.
- Each has a real cost: Backendless free tier limited to 50 API requests per minute and 20 database tables; OutSystems application Objects grow with every screen, table and API an app gains, so a successful app that keeps adding features can push the account into AO overage charges that were not modelled at initial budget time.
- They diverge on capability: Backendless covers REST API, OutSystems covers Visual application modelling.

OutSystems

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Backendless
- Free tier limited to 50 API requests per minute and 20 database tables
- Smaller community and integration ecosystem compared to Firebase or AWS
- Customization beyond codeless tools requires developer expertise
- Limited documentation for advanced use cases and edge cases
OutSystems
- Application Objects grow with every screen, table and API an app gains, so a successful app that keeps adding features can push the account into AO overage charges that were not modelled at initial budget time.
- Internal users are sold in packs of 100 and external users in packs of 10,000, so a company just over a pack boundary in either category pays for a full additional pack rather than a handful of extra seats.
- Entry-level ODC pricing starts around 36,300 US dollars a year before any AO overage or extra user packs, which puts it out of reach for smaller teams evaluating low-code options.
- Cloud infrastructure and hosting costs are frequently separate from the platform licence, so the all-in bill is higher than the headline subscription figure suggests.
- Migrating a large application portfolio off OutSystems once built is difficult, since the generated code and platform-specific patterns are not designed for a clean export to standard frameworks.
