Paligo was built for documentation professionals who need to manage a large volume of complex content. To manage and organize this documentation efficiently, content reuse is essential. The Paligo CCMS is an excellent choice for companies who need to leverage the benefits of content reuse for better business outcomes.  Content reuse helps to streamline the content creation process as it saves time, money, and improves the quality of output. The single sourcing features eliminate duplication of content and optimize the content creation process. Additionally, the modern SaaS UI lets content creators of all levels of proficiency to easily grasp the fundamentals of structured authoring.

 Our goal is to make structured authoring more accessible to a wider audience by simplifying and demystifying the process. This is achieved through our intuitive and user-friendly CCMS, which is both powerful and robust, enabling our customers to easily author, manage, translate, and publish content.

Xano is the unified backend for building and deploying production-grade apps and AI agents. Instead of stitching together databases, runtimes, APIs, auth, integrations, and monitoring—plus a separate orchestrator for agents—Xano provides everything in one secure, scalable platform. Teams can model data, compose logic, expose secure APIs, and integrate with any system, while AI agents can use data and APIs, call external tools, and run server-side with observability and guardrails. Build visually, with AI, or in code from your IDE, then deploy with one click and scale automatically. Xano works with any frontend, including Lovable, Bolt, WeWeb, Retool, and custom code, so you don’t need to rebuild as you grow. Compliance, reliability, and scaling are built-in, enabling teams to focus on the business logic that makes their software unique.

Spend your time on writing high quality documentation, not on the tools to make your documentation work. Read the Docs simplifies software documentation by automating building, versioning, and hosting of your docs for you. We will host your documentation for free, forever. There are no tricks. We help over 100,000 open source projects share their docs, including a custom domain and theme. Whenever you push code to your favorite version control service, whether that is GitHub, BitBucket, or GitLab, we will automatically build your docs so your code and documentation are never out of sync. We build and host your docs for the web, but they are also viewable as PDFs, as single page HTML, and for eReaders. No additional configuration is required. We can host and build multiple versions of your docs so having a 1.0 version of your docs and a 2.0 version of your docs is as easy as having a separate branch or tag in your version control system.
