German GPL-licensed open-source survey platform (LimeSurvey GmbH Hamburg, project since 2003), self-host first.

Warum diese Bewertung?

LimeSurvey GmbH (Hamburg, Germany; founded August 2015, but the open-source LimeSurvey project itself dates to 2003 by Carsten Schmitz who remains Founder + CTO) is one of the longest-running open-source survey platforms in Europe, GPL-2.0+ licensed with source on GitHub, deployable on customer infrastructure (PHP + MySQL/PostgreSQL/SQLite/MSSQL) for full sovereignty; also offered as managed LimeSurvey Cloud — rated 4/5: a strong EU-owned open-source profile with no CLOUD Act exposure, but the DPA is not publicly accessible — it is reachable only inside a customer account; the rubric reserves 5/5 for a publicly accessible DPA.

OVERVIEW

About LimeSurvey

Schmitz remains Founder + CTO. The platform is licensed under **GPL v2 (or later)** with source on GitHub, runs on PHP with MySQL / PostgreSQL / SQLite / MSSQL backends, and is widely deployed in EU universities, public administrations, and research institutions.

PUBLIC DOCUMENTS

Öffentliche Dokumente

Vendor does not publish a public DPA. Without a publicly accessible Data Processing Addendum, small EU customers cannot self-serve the processor agreement — this caps the compliance score (see How we score).
