Low-code platforms cover a wide spread of needs here: government form building, spreadsheet-like databases, chatbot builders, internal-tool frameworks, admin panels, surveys, and broader app platforms. The ToolVitals June 2026 data gives each listed tool a health score, shipping score, ToolVitals score, GitHub stars, openness_label, license_label, and status so readers can compare maintainability signals without treating all low-code tools as interchangeable.
This ranking includes open/source-visible tools only and orders them by ToolVitals score first, with GitHub stars used only as a secondary popularity signal when scores tie. The list is entirely OSI-approved OSS in the supplied data, with license_label values such as MIT, Apache-2.0, EPL-2.0, AGPL-3.0, GPL-3.0, LGPL-2.1, and BSD-3-Clause shown as given.
