--- title: "dbos-transact-py vs viewflow" type: "comparison" canonical_url: "https://www.graphcanon.com/compare/dbos-inc-dbos-transact-py-vs-viewflow-viewflow" tools: ["dbos-inc-dbos-transact-py", "viewflow-viewflow"] --- # dbos-transact-py vs viewflow *GraphCanon updated Sep 20, 2026* ## Verdict Pick dbos-transact-py if supports Python-based workflows and microservice orchestrations backed by PostgreSQL and SQLite databases for durable execution; pick viewflow if viewflow is an open-source workflow and process engine for Django applications that allows developers to specify workflows directly in Python code. [dbos-transact-py](https://docs.dbos.dev) reports 1.6k GitHub stars, 95 forks, and 4 open issues, last pushed Sep 19, 2026. [viewflow](http://viewflow.io) has 2.9k stars, 413 forks, and 19 open issues, last pushed Sep 13, 2026.
