Stoplight and Theneo solve different halves of the API lifecycle. Stoplight is design-first: you model your API in a visual OpenAPI editor, enforce standards with Spectral, and generate mock servers with Prism. It's genuinely good at that work. Theneo starts where the specification ends and generates the documentation itself: endpoint descriptions, multi-language code samples and changelogs written from your spec, rather than only rendering what the spec already contains. On top of that sit AI-powered search with conversational answers, a collaborative editor non-engineers can actually use, and MCP server generation with llms.txt so AI agents can discover and query your docs. If your main need is API governance and design modelling, Stoplight is the better tool. If it's publishing and maintaining a developer portal, that's the gap Theneo fills.
Yes, Theneo supports real-time collaboration and version control for API documentation teams. It features a Notion-like editor where developers, writers, and PMs can edit simultaneously with comments, suggestions, and approval workflows. Theneo also integrates with GitHub and GitLab, supporting both bi-directional and uni-directional sync through CI/CD. This allows non-developers to contribute easily, unlike traditional PR-based workflows that require constant engineering involvement.
Theneo is compliant with SOC 2, GDPR, ISO 27001 and ISO 9001. Data is encrypted with AES-256 at rest and TLS 1.2+ in transit, with comprehensive audit logs and proactive security monitoring. Access is controlled through SSO and SAML for both your internal team and your external API consumers, granular role-based permissions covering who can edit, review, deploy and view, and endpoint-level privacy settings that let you keep some APIs public while restricting sensitive endpoints to specific groups inside the same portal. Teams whose security review won't approve documentation on shared infrastructure can self-host Theneo via Docker on AWS, Azure, Google Cloud or their own environment, with full data sovereignty.
Yes, and migration is free. Because Stoplight projects are built on OpenAPI, you export your specifications and import them into Theneo, which generates structured documentation with descriptions, code samples and interactive examples. Theneo supports OpenAPI, Swagger, Postman, GraphQL and gRPC, so your whole API catalogue moves at once, and your existing URL and slug structure is preserved, so you avoid the mass redirect project that usually comes with changing documentation platforms. A migration specialist handles spec import, structure recreation, CI/CD sync configuration, branding and custom domain setup, and go-live. Most teams are fully live within a few days. The realistic caveat: if you rely on Stoplight's mocking and style-guide governance, plan for those to stay in your existing toolchain, since Theneo doesn't replace them.
Yes. Theneo powers documentation for more than 18,000 companies, from startups to Fortune 500 organizations including Ticketmaster and FIS, and is built for complex API ecosystems spanning multiple teams, products and audiences. Enterprise customers get SSO and SAML, role-based access control, audit logs, SOC 2, GDPR and ISO 27001 compliance, self-hosted deployment, and SLA-backed support through Slack and Teams with a named account manager. One point worth raising honestly at enterprise scale: Stoplight has been part of SmartBear since 2023, and its capabilities are being progressively consolidated into SmartBear API Hub alongside SwaggerHub. Stoplight itself remains active, but if you're planning a multi-year documentation investment, it's worth asking SmartBear directly which components stay standalone and how API Hub pricing applies at renewal.
Migrating from Stoplight is straightforward and free. Since Stoplight projects are built on OpenAPI specs, you simply export your specs and import them into Theneo. Our team handles the heavy lifting: spec import, documentation structure recreation, CI/CD pipeline setup with bi-directional or uni-directional sync to your repo, branding and custom domain configuration, and go-live — typically within a few days. We support OpenAPI, Postman, GraphQL, gRPC, and Swagger formats, so your entire API catalog moves at once.
Full control over layout, design, and branding. White-label your docs completely — custom domains, CSS/JS injection, and portal templates so your documentation looks like your product, not a third-party tool. Build multi-API developer portals that combine endpoint reference, user guides, tutorials, and SDK docs in one hub. Unlike Stoplight, which limits you to basic API reference pages with minimal customization, Theneo lets you mix content types freely and design deeply nested navigation structures.
Yes. SSO/SAML integrations for both your internal team and external API consumers, with granular role-based access control to manage who can edit, review, deploy, and view documentation. You can also set endpoint-level privacy — keep some APIs public while restricting sensitive endpoints to specific user groups, all within the same portal.
Dedicated support through Slack and Teams with SLA-backed response times. Enterprise customers get a named account manager, direct access to product engineers, and priority feature requests. For teams migrating from Stoplight, we assign a dedicated migration specialist to handle the entire transition end-to-end.
Theneo is compliant with SOC 2, GDPR, ISO 27001, and ISO 9001. All data is encrypted with AES-256 at rest and TLS 1.3 in transit. Enterprise customers can self-host on their own infrastructure via Docker for complete data sovereignty. We also provide comprehensive audit logs and proactive security monitoring.
Direct access to our product engineers, designers, and API specialists who collaborate with your team to tailor the platform to your workflow. For Stoplight migrations specifically, we provide a dedicated specialist who manages the entire process: spec import, structure recreation, CI/CD sync configuration (bi-directional or uni-directional), branding setup, and go-live support. Post-migration, we partner with you to monitor usage, optimize developer experience, and drive API adoption.
