LongLink.dev's answer
AI has made software dramatically faster and cheaper to create, making custom software practical for many more business processes. But faster development does not automatically produce maintainable software. LongLink was created to combine this new economics of software creation with conventional engineering practices: clear architecture, testing, versioning, review, deployment, and ownership of the process.
LongLink.dev's answer
Organizations that need custom internal business applications, and the developers who build them. LongLink is particularly suited to processes currently spread across SaaS tools, spreadsheets, databases, documents, manual work, and disconnected systems.
LongLink.dev's answer
LongLink is designed for processes that are too specific for generic SaaS and too important to become opaque low-code configurations. Developers retain full control of the implementation in Python, while LongLink provides the common infrastructure required to deploy and operate it. The result is custom software without rebuilding the same platform foundations for every application.
LongLink.dev's answer
LongLink turns a business process into a complete application. Human tasks, automation, data, permissions, and custom logic live together in one solution, with clear ownership and a clear separation between what is a human decision and what is a machine task.
