Open-source Bizagi alternatives

Corteza is a low-code platform that lets teams build and iterate on CRM, business process, and other structured data applications quickly. It also supports intelligent business process workflows and connects to almost any data source. It is written in Go, with a Vue front end, and released under the Apache-2.0 license. It is maintained by Planet Crust, its founder.

Key characteristics include a standards-oriented approach using established data formats, flat role-based access control that supports complex internal security policies, privacy features that help comply with data protection regulations, accessibility following WCAG 2.1, and an API-centric design that makes integration with external services and other Corteza instances straightforward. Applications can be customized from translations and terminology up to entirely new low-code apps.

Planet Crust offers hosted Corteza cloud instances as the easiest way to start, and a DevOps guide covers self-hosting along with backup, restore, and email relay topics. Corteza suits organizations that want an open-source alternative to proprietary low-code CRM platforms and need control over their data.

REI3 is a free and open low-code platform for building and hosting business applications with full control and ownership. It targets organizations that want to replace spreadsheet-based solutions with proper multi-user apps, run them in the cloud or on-premise, and avoid walled gardens and cloud-only SaaS. Created applications can be used, shared or even sold.

Applications can summarize records, do date calculations and apply business rules, show tasks on Gantt charts, diagrams and dense lists, and include workflows such as forms that change with a record's state, PDF export and notifications. Roles and access policies restrict access globally or per record, and built-in end-to-end encryption comes with key management. Integration options include serving and calling REST endpoints, CSV import and export and ICS calendar access. The platform also covers mobile use with PWA features, full-text search, input types such as signatures and bar or QR code scanning, password policies and brute-force protection.

REI3 is written in Go and JavaScript, uses multi-core processing and bi-directional data channels for speed, and has downloads, documentation, a live demo and a catalog of applications. Its license is listed as Other.

Joget is an application platform that combines rapid application development, business process automation and workflow management in a visual, web-based builder. Business and technical teams can use it together to build full enterprise applications without much hand coding, aiming to shorten delivery from months to weeks or days. Apps built on it are mobile ready and cloud ready, and the platform offers APIs for integration and a plugin architecture for extension.

The README describes a marketplace where ready-made apps, plugins and templates can be downloaded, along with a community Q&A forum, a knowledge base, video tutorials, an online academy and translations in more than twenty languages. Deployment is flexible: on-premise, on-demand cloud, Docker, Kubernetes, Cloud Foundry, OpenShift and several cloud marketplaces are listed.

Licensing is split. Joget Community Edition is released under GPL version 3, while the Professional, Enterprise and Large Enterprise editions are covered by a commercial end-user license agreement. The core is written in Java. It suits organizations that want to digitize processes such as approvals and forms with a platform they can run themselves.
