Instead of Doccano
Doccano alternatives
Doccano gives machine-learning practitioners a free, open-source workspace for preparing labeled data. Projects can import datasets, add users, support collaborative annotation, and export results. Its supported tasks include text classification, sequence labeling, and sequence-to-sequence annotation, while image, text, audio, and video annotation, model-assisted labeling, review workflows, and multi-language support extend its use. A REST API connects scripts and models, and deployment options include pip, Docker, Docker Compose, source installation, and cloud setups on Linux, Windows, or macOS.

Readers may look elsewhere when they need richer computer-vision curation, more specialized annotation types, or a browser tool designed for offline use. Doccano remains free, but SQLite is its default database and upgrades using SQLite can lose the database. When switching, weigh the media your team handles, annotation and feedback methods, model assistance, import and export formats, integrations, collaboration, privacy, and deployment. The right alternative depends on whether your priority is broad multimodal labeling, visual dataset management, local privacy, or a focused workflow.
