Frequently Asked Questions

Everything you need to know about switching from Stoplight to Theneo.

theneo icon

Theneo is an AI-powered API documentation platform, while Stoplight focuses on API design and specification workflows. Theneo generates complete documentation from your API specs — including endpoint descriptions, code samples, and changelogs — not just rendering them. It also includes AI search, real-time collaboration for non-developers, and MCP server generation with llms.txt for AI agent discoverability. In comparison, Stoplight is primarily a design-first tool with more limited documentation automation and fewer AI-driven capabilities.

theneo icon

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 provides enterprise-grade security with SOC 2, GDPR, and ISO 27001 compliance. It includes SSO/SAML, granular role-based access control, audit logs, and endpoint-level privacy settings. For teams with strict requirements, Theneo also supports self-hosted deployment on AWS, Azure, or Google Cloud, giving full control over data and infrastructure.

Yes, migrating from Stoplight to Theneo is straightforward and typically takes a few days. You can import OpenAPI, Swagger, Postman, GraphQL, or gRPC files, and Theneo automatically generates structured documentation from your specs. The platform also supports CI/CD sync, custom domains, and full documentation setup, making it easy to transition without rebuilding everything from scratch.

theneo icon

Yes, Theneo is built for enterprise teams that need secure, scalable API documentation and collaboration. It supports SSO/SAML, role-based access control, audit logs, and compliance with SOC 2, GDPR, and ISO 27001 standards. Enterprise customers can also deploy Theneo on their own infrastructure and benefit from SLAs and dedicated support.Theneo is used by 17,000+ companies, including large organizations like Ticketmaster and FIS, and is designed to handle complex API ecosystems with multiple teams and workflows. Compared to tools primarily focused on API design, Theneo provides a more complete developer portal with AI-powered documentation, collaboration, and ongoing product development tailored for modern enterprise needs.

How does migration from Stoplight to Theneo work?

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.

What customization options are available for documentation and developer portals?

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.

Does Theneo support Single Sign-On (SSO) and custom roles and permissions?

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.

What type of support does Theneo offer to enterprise customers?

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.

How does Theneo ensure the security and compliance of our data?

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.

What kind of support and collaboration can we expect from the Theneo team?

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.
