OutSystems

OutSystems is an enterprise low-code and AI-assisted application development platform company, founded in 2001 and headquartered in Boston, Massachusetts with engineering in Lisbon, Portugal. Its two product lines are OutSystems 11 (O11), the self-managed/PaaS platform, and OutSystems Developer Cloud (ODC), the cloud-native successor. ODC publishes a documented set of public REST APIs covering user and access management, portfolio, asset repository, asset and environment configurations, build operations, deployments, dependency and impact analysis, code quality, native mobile builds, external library generation, and subscription/entitlement usage. All ODC REST APIs authenticate with OAuth 2.0 client-credentials via a per-tenant OIDC discovery document, use offset/limit pagination, and are rate limited per API domain. OutSystems also ships a remote MCP server (early alpha) that exposes app inspection, the Mentor OML editing session, publishing, deployments, external libraries and environments to AI coding agents.

OutSystems publishes 13 APIs on the APIs.io network, including ODC User and Access Management API, ODC Portfolio API, ODC Portfolio API (v1), and 10 more. Tagged areas include Company, Low-Code, Application Development, Platform as a Service, and DevOps.

OutSystems’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 31 more developer resources.
