The short version

  • Only Appsmith has a free tier, so it costs nothing to try first.
  • Each has a real cost: Appsmith the free cloud tier is capped at 5 users, 5 workspaces and 3 Git repositories; 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: Appsmith covers Drag-and-drop builder, OutSystems covers Visual application modelling.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Appsmith

  • The free cloud tier is capped at 5 users, 5 workspaces and 3 Git repositories
  • Workflows, custom roles and audit logs all require the Business plan at $15 per user per month
  • SAML and OIDC single sign-on need Enterprise, which starts at $2,500 a month with a 100 user minimum
  • Embedding an app privately is Enterprise only; the lower tiers embed publicly
  • Managed hosting is an Enterprise add-on rather than an included option

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.
