refine is an open-source, headless React framework for rapidly building enterprise web applications. It eliminates many repetitive tasks like
➡️ CRUD operations
➡️ State management
➡️ Routing
➡️ Authentication
➡️ Access Control
➡️ i18n
and saves days of development time.
So far, thousands of great projects have been built by 15,000+ monthly active refine developers. Use cases are ranging from admin panels, dashboards, and internal tools to B2B solutions and complex SaaS interfaces.
refine is backed by a strong community featuring 16K GitHub stars ⭐️, 180+ contributors and 2,500 Discord members.
Thanks to it's unique "Headless UI" approach, refine works with any custom design. It has also ready-made integrations with 4 most popular UI frameworks: Ant Design, Material UI, Chakra UI and Mantine. refine is totally backend agnostic and it can connect to 15+ backend services out-of-the-box, incl. custom REST & GraphQL API's.
With refine, developers always have 100% control over their projects as they build, style and deploy the way they like.
Retool is a low-code platform designed to accelerate the building of custom internal tools for enterprises, enabling engineering teams to ship operational software up to 10 times faster. It serves thousands of companies across various sectors, including large enterprises like Amazon and DoorDash, by providing a drag-and-drop interface combined with powerful backend integrations and enterprise-grade features such as granular access controls and audit logging. Retool’s mission is to transform how developers build software by removing tedious development tasks, allowing teams to focus on core product innovation and operational excellence. This approach addresses the massive, often overlooked market of internal tooling, which represents trillions of dollars in spend and millions of developer hours annually[1][2][5].
Founded around 2017 by David Hsu and his team, Retool emerged from the founders’ frustration with the inefficiency of building internal tools from scratch. Hsu, drawing on his experience as a developer, envisioned a platform that could simplify the creation of internal apps by focusing on core UI components like tables, buttons, and text inputs. Early traction came from testing the product with startups in Y Combinator and other cohorts, validating the need for a faster, more flexible internal tooling solution. Retool publicly launched in 2018 with around 40 customers and $2 million in ARR, emphasizing a high-quality developer experience to meet the rigorous standards of its user base[1][3].
Retool rides the growing trend of low-code/no-code platforms that democratize software development and accelerate digital transformation within enterprises. The timing is critical as companies face increasing pressure to optimize operations and scale efficiently without proportionally increasing engineering resources. Market forces such as the rising complexity of internal workflows, the demand for rapid iteration, and the expansion of AI-driven automation favor Retool’s platform. By enabling not only developers but also analysts and domain experts to build custom solutions within enterprise guardrails, Retool is reshaping who can create software and how internal tools are developed and maintained[1][4][7].
Looking ahead, Retool is positioned to deepen its impact by integrating advanced AI capabilities, such as natural language to code generation and intelligent automation agents, which will further lower barriers to building complex internal applications. As enterprises continue to prioritize operational agility and automation, Retool’s platform is likely to expand its footprint, influencing the broader ecosystem by setting new standards for developer productivity and internal tooling innovation. The company’s ongoing focus on security, scalability, and user experience will be key to sustaining growth and maintaining leadership in the enterprise low-code space[4][7]. Retool’s evolution from a simple internal tool builder to a comprehensive enterprise AppGen platform underscores its commitment to rethinking software development for the future[1][4].
