Appsmith vs OutSystems (2026): which should you pick?

Pick Appsmith if

• Fits if you build internal tools and can self-host to pay nothing
• Works for small teams of up to 5 on the free cloud plan

Look elsewhere if

• Tight if you grow, as the free cloud plan stops at 5 users, 5 workspaces and 3 Git repos
• Pricey if you need SSO, since SAML, OIDC and SCIM are Enterprise at $2,500 a month
• Watch out: Workflows, audit logs and custom roles start on Business
• Watch out: the page does not say whether the $15 Business price is monthly or yearly

Pick OutSystems if

• Fits if you work for a company that needs governed, production-grade apps
• Works for developers who want to learn the platform on the free Personal Edition

Look elsewhere if

• Skip it if you need a price you can read, as pricing is a custom quote
• Not for you if you want to run a live app free, as the Personal Edition is a development runtime
• Too light on its own if you need 24x7 support, 99.95% uptime or SOC 2, which are paid add-ons
• Watch out: self-hosting is only available on certain plans

Appsmith
