Open-source survey and experience management platform with self-hosting option
Formbricks is an open-source survey and user research platform offering in-app surveys, link surveys, and website surveys with a self-hosted deployment option. It targets SaaS companies and product teams who want to run targeted in-product surveys (triggered by user actions, segments, or attributes) with full data ownership — an open-source alternative to Intercom surveys and Qualaroo.
Formbricks is a strong fit if its core strengths match your workflow, budget, and support needs. Use the quick signals below before opening the full review.
Formbricks addresses a specific gap: in-app surveys that are open-source, self-hostable, and triggered by actual user behaviour rather than showing to everyone randomly. For SaaS product teams who want targeted user research without sending data to third-party survey platforms, Formbricks is the most capable open-source option.
Formbricks' SDK embeds in the product application and surfaces surveys triggered by user events — a churn survey appears when a user downgrades, an NPS survey appears after 90 days of use, a feature feedback survey appears the first time a user completes a specific action. This event-triggered targeting produces dramatically higher relevance than time-based or random survey triggers, improving response rates and data quality.
Formbricks' self-hosted deployment runs on the organisation's own servers — all survey responses stay in the organisation's database, processed by the organisation's infrastructure, under the organisation's data governance. For European SaaS companies with GDPR obligations, financial services with data locality requirements, and healthcare companies with sensitive user data, self-hosting eliminates the third-party data processor relationship that cloud survey tools create.
Formbricks' AGPL-licensed codebase can be inspected, modified, and extended by the organisation's development team. Custom survey templates, custom triggers, custom integrations, and modified UI are all possible without waiting for the vendor to implement them. For developer-led product teams, this flexibility is a meaningful advantage over commercial black-box tools.
Score: 7.2/10 — Best open-source in-app survey tool for SaaS teams; in-app integration requires technical setup and is more specialised than general form builders.
