Twenty is a modern, open-source CRM alternative to Salesforce—fully customizable, affordable, and powered by the community.

The PH Community (ph) is a forum and resource hub for PHP developers, providing discussions, tutorials, and insights on PHP programming and web development. Developers can ask questions, share knowledge, and collaborate with fellow PHP enthusiasts on topics such as PHP frameworks, CMS platforms, and database integration. Additionally, PH Community covers PHP events, job opportunities, and community initiatives, fostering a supportive and engaged PHP developer community.

Product Hunt

Twenty 2.0 is an open-source CRM platform launching as a developer-extensible alternative to Salesforce and HubSpot. The major addition is a new SDK (npm i twenty-sdk) that lets developers define data models, custom objects, workflows, layouts, and widgets in code within their own repos. It ships with built-in AI chat, custom agents, serverless functions, full layout and navigation customization, and remains self-hostable. The goal is to give teams a CRM they fully own and can build on top of, without vendor lock-in.
