Open-source survey tools, compared honestly

Four open-source alternatives to Google Forms that are actively maintained and can run on your own server — Jackpoll, LimeSurvey, Formbricks and Nextcloud Forms — and the situation each one is best at.

Which open-source survey tools are worth comparing?

The open-source survey tools worth comparing in 2026 are Jackpoll, LimeSurvey, Formbricks and Nextcloud Forms: each publishes its full source under an open-source licence, each was still being actively developed when this page was reviewed, and each can run on infrastructure you control. That is the bar for this page, and it is the reason these four are here.

Two popular projects are left out on purpose. SurveyJS is an open-source JavaScript form library — excellent if you are building your own form system, but a toolkit rather than a finished survey tool. Typebot is a self-hostable chatbot builder, which overlaps with conversational forms but solves a different problem.

About this comparison

This page is written by the Jackpoll project, so it is not neutral — but every fact about the other tools is taken from their own licence files and READMEs, and it avoids prices and plan limits, which change without notice. Last reviewed September 2026; check each project's current documentation before deciding.

When is LimeSurvey the better choice?

LimeSurvey is the better choice when you need a long-established survey platform for detailed, multi-page questionnaires and already run PHP hosting. It has been developed since 2003, is licensed under the GPL (version 2 or later), and runs on any PHP-capable web server with a database — a setup many universities and hosting providers already support. The vendor also offers a hosted version for those who would rather not operate it.

When is Formbricks the better choice?

Formbricks is the better choice when the survey lives inside your product: it is built for in-app, website, link and email surveys that collect user and customer insight along a product journey. It is written in TypeScript on Next.js, self-hosts with Docker, and is also available as a hosted cloud. Its licence is open core — the core application is AGPLv3, while enterprise modules sit under a separate licence.

When is Nextcloud Forms the better choice?

Nextcloud Forms is the better choice when your organisation already runs Nextcloud and needs simple forms rather than a separate survey platform. It is an AGPL-licensed app that installs into an existing Nextcloud instance, keeps responses on that instance, and deliberately sticks to the essentials; results can be exported as CSV in the same format Google Forms uses.

Jackpoll

When is Jackpoll the better choice?

Jackpoll is the better choice when a survey also has to work in a room: alongside forms and auto-graded quizzes it has live word clouds, real-time results for a projector and a presenter-led live quiz game. It is the only one of the four under the permissive MIT licence, it has a free hosted version running on servers in Germany as well as Docker stacks for self-hosting, and it ships iOS and Android apps.

The honest caveat: Jackpoll is by far the youngest project here — its repository was created in 2026, while the others have years of production use behind them. If a long track record matters more to you than live formats or a permissive licence, weigh that accordingly.

Frequently asked questions

What is the best open-source alternative to Google Forms?
It depends on the job. LimeSurvey suits detailed research questionnaires, Formbricks suits surveys inside a product, Nextcloud Forms suits organisations already on Nextcloud, and Jackpoll suits surveys and quizzes that also need live formats in a room.
Which open-source survey tool has the most permissive licence?
Jackpoll, under MIT. LimeSurvey uses the GPL, and Formbricks and Nextcloud Forms use the AGPL: if you modify them and let others use the result — including over a network — you have to offer those users your modified source. MIT asks only that the licence notice is kept.
Can all of these tools be self-hosted?
Yes. Jackpoll and Formbricks ship Docker setups, LimeSurvey runs on a PHP web server, and Nextcloud Forms runs inside your own Nextcloud.
