Qworum

The baseline Web is incredibly limiting as an application platform. Build your webapps on Qworum. Provide 𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗲𝗱 𝘂𝘀𝗲𝗿 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲𝘀 𝘁𝗵𝗮𝘁 𝘀𝗽𝗮𝗻 𝗦𝗮𝗮𝗦 𝗮𝗻𝗱 𝗶𝗻𝘁𝗲𝗿𝗻𝗮𝗹 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀. Improve the security postures of your applications. WHY QWORUM? The current Web is still fundamentally a content platform, and although it is widely used for providing applications, it's still missing many features that are essential for applications. Qworum upgrades the Web with application-centric features: ➜ 𝗱𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗲𝗱 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 whose frontends can span multiple websites (surpasses micro-frontends in many scenarios, useful for large webapp projects involving many dev teams etc), ➜ zero-trust 𝘀𝗲𝗰𝘂𝗿𝗲 𝗮𝗻𝗱 𝗺𝘂𝗰𝗵 𝗲𝗮𝘀𝗶𝗲𝗿 𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀 at the frontend (surpasses OAuth in security through interactivity, and integrations are much easier to implement than at the backend), ➜ 𝗻𝗮𝘁𝗶𝘃𝗲 𝗥𝗗𝗙 𝘀𝘂𝗽𝗽𝗼𝗿𝘁 for knowledge applications, ➜ 𝗮 𝗻𝗲𝘄 𝘁𝘆𝗽𝗲 𝗼𝗳 𝗪𝗲𝗯 𝗔𝗣𝗜 where the endpoints are interactive, ➜ more to come. Qworum is easy to start with: 1️⃣ 𝗘𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝗪𝗲𝗯 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗰𝗮𝗻 𝘀𝘁𝗮𝗿𝘁 𝗯𝘆 𝗽𝗿𝗼𝘃𝗶𝗱𝗶𝗻𝗴 𝗮 𝗤𝘄𝗼𝗿𝘂𝗺 𝗔𝗣𝗜 in addition to their other Web-based APIs. Use your existing software stack (MERN, JAMstack, low-code tools/platforms such as Retool, etc); the only requirement is a JavaScript-enabled browser at the frontend (currently not supported: Safari, Firefox). 2️⃣ 𝗡𝗲𝘄 𝗪𝗲𝗯 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗰𝗮𝗻 𝗯𝗲 𝗱𝗲𝘀𝗶𝗴𝗻𝗲𝗱 𝗮𝘀 𝗤𝘄𝗼𝗿𝘂𝗺 𝗔𝗣𝗜𝘀 from the start. Often there's no need for a separate Web API. Qworum is an AI-ready platform and aims to become AI-native.

Routebase

Routebase is an API lifecycle platform built on a single source of truth. Instead of scattering your API across a design tool, separate docs, standalone mocks, a testing tool, and monitoring — each drifting on its own — Routebase derives all of them from one living OpenAPI spec. Change the spec, publish, and it catches what drifted before your consumers do. Teams use Routebase to design APIs in a visual editor (no hand-edited YAML), branch and review specs like code, publish a docs portal that never goes stale, mock endpoints for parallel frontend/backend work, and run contract, security, and drift tests against live environments. Every workspace also ships a built-in MCP server, so AI agents operate on the same source of truth under your team's permissions.

Xapi Platform

Xapi is an API design platform that enables secure and efficient designing and managing of high-quality APIs. With the API design-first approach in mind, Xapi is geared toward documenting API requirements, maintaining API hierarchies, Kanban-based API tracking, API management workflows, and user management. Xapi facilitates productively investing your precious time in crafting your next best API strategy, Otherwise, you would have spent on the nitty-gritty of manual API designing.
