Open-Source and Free Course Evaluation Software (2026): A European Buyer's Guide

Short answer: If your priority is zero licence cost and full control over where student data lives, the two genuinely open-source options worth shortlisting are LimeSurvey (released under the GPL) and Formbricks (AGPLv3) — both self-hostable inside the EU. If "free" simply means free-of-charge, Google Forms, Microsoft Forms and the free tier of LamaPoll will also collect responses at no cost. None of these tools was designed for course evaluation specifically, and every one of them hands the analytical work — question design, coding thousands of open-text comments, and closing the loop with students — back to your team. That labour, not the licence fee, is where the real cost of course evaluation actually sits.

This guide is for QA directors, heads of teaching and learning, institutional-research staff and IT procurement leads who have been asked, reasonably, "why pay for evaluation software when free tools exist?" Answering it honestly means separating three things that usually get lumped together.

"Open source" is not the same as "free"

Three distinct claims hide behind the word free, and conflating them leads to bad procurement decisions:

Open source (FOSS). The source code is published under a licence (GPL, AGPL, MIT and similar) that lets you run, inspect, modify and self-host the software. There is no licence fee, but there is a real cost: servers, upgrades, security patching, and staff who can operate a PHP or Docker stack. Open source buys you control and auditability, not the absence of cost.
Free tier of a proprietary tool. A commercial vendor offers a no-cost plan with caps — on responses, questions, seats or features — as an on-ramp to a paid plan. The code is closed; you cannot self-host.
Free-of-charge proprietary. Tools such as Google Forms are genuinely free to use but proprietary, funded by the wider platform they belong to. You accept the vendor's data-processing terms as they stand.

For a university, the second-order questions matter more than the sticker price: Where does the data live? Who can be re-identified in a small cohort? Who codes the open text? Does anything actually change for students afterwards?

The genuinely open-source options

LimeSurvey (GPL)

LimeSurvey is the most established open-source survey platform in higher education, used across dozens of countries by universities, research groups and public bodies. The Community Edition is fully open source under the GPL, is a PHP application backed by MySQL, MariaDB or PostgreSQL, and gives you every core feature at no licence cost. Its strengths are exactly the ones long-form academic evaluation needs: a large range of question types, conditional logic and branching, quotas, multilingual questionnaires, and exports in the formats analysts expect (SPSS, R, CSV, Excel). Because you host it, GDPR compliance and EU data residency are within your control rather than a vendor's promise.

The trade-off is operational. Someone has to install, secure, upgrade and back up the instance; someone has to design a defensible questionnaire; and someone has to read and code the free-text comments by hand. LimeSurvey collects feedback superbly. It does not analyse it for you.

Formbricks (AGPLv3)

Formbricks is a newer, developer-friendly experience-management platform, open source under the AGPLv3, that you can self-host end-to-end with Docker or run on its GDPR-compliant cloud. It shines at in-app and link-based micro-surveys and has a clean, modern authoring experience. For course evaluation it is best suited to short, targeted pulse checks rather than institution-wide, logic-heavy instruments; it carries fewer question types and less of the statistical-export machinery than LimeSurvey. As with any self-hosted tool, the licence is free and the running and analysis are not.

Free-of-charge, but proprietary

Google Forms and Microsoft Forms

Both are genuinely free and quick to stand up. Google Forms is unlimited and frictionless, but data is processed on Google infrastructure — a point you must reconcile with Schrems II and your institution's data-transfer position. Microsoft Forms is usually already covered by an existing Microsoft 365 Education tenancy, which can put data governance on firmer, EU-region footing. Both are fine for a one-off module survey. Neither offers question banking, bias-aware standardisation, qualitative coding, longitudinal cohort reporting or action tracking — the machinery that turns raw feedback into accreditation-ready evidence.

LamaPoll (free tier)

LamaPoll is a German, GDPR-first survey tool with hosting in Germany and ISO/IEC 27001 certification — an attractive data-residency story for German and wider EU institutions. It is proprietary, not open source; its free tier collects surveys at no cost but caps volume, so it functions as a trial rather than an institution-wide solution. For departments whose overriding constraint is German data hosting on a small budget, the free tier is a reasonable starting point.

Comparison at a glance

Tool	Licence / cost model	Self-host in EU	Built for course evaluation?	Open-text analysis	Best fit
LimeSurvey	Open source (GPL), free licence	Yes	No (general survey)	Manual	Logic-heavy, multilingual, data-sovereign surveys with in-house ops
Formbricks	Open source (AGPLv3), free licence	Yes	No (experience mgmt)	Manual	Short in-app pulse surveys, dev-friendly teams
Google Forms	Free-of-charge, proprietary	No	No	Manual	Quick one-off module surveys
Microsoft Forms	Free with M365 EDU, proprietary	Tenant-dependent	No	Manual	Institutions already in the Microsoft estate
LamaPoll (free tier)	Free tier, proprietary	Yes (DE hosting)	No	Manual	Budget German/EU data-residency pilots
Koji	Commercial, paid	Yes (EU/GDPR)	Yes (AI-native)	Automatic thematic analysis	Scale, qualitative depth, closing the loop, accreditation evidence

As of publication, LimeSurvey and Formbricks publish open-source licences and self-host options; free-tier limits for proprietary tools change, so verify current caps before committing.

The cost that never appears on the invoice

Every free and open-source tool above solves collection. The expensive part of course evaluation is everything after collection:

Coding the open text. A mid-sized faculty generates thousands of free-text comments a semester. Reading and thematically coding them by hand is the single largest hidden cost of "free" evaluation, and it is where analyst time quietly disappears.
Response rates. Static one-shot forms are exactly the format most exposed to survey fatigue and non-response bias. A dead 18% response rate produces data you cannot defend to a programme committee, whatever the licence cost.
Closing the loop. ESG and every European quality framework expect evidence that feedback changed something. A form has no concept of an action, an owner or a follow-up — so loop closure becomes a manual spreadsheet exercise that rarely survives a busy term.

This is the design gap a dedicated AI-native platform addresses. Koji uses the same conversational AI interview engine that powers the main Koji research platform for general customer and user research: instead of a static Likert grid, an AI moderator conducts a short, standardised, bias-aware interview with each student, probes vague answers ("what specifically made the assessment unclear?"), and then produces the thematic analysis automatically rather than leaving it to a human coder in August.

When open-source or free is the right choice

Being honest here builds trust — and sometimes the free tool genuinely wins. Reach for LimeSurvey, Formbricks or a free form when:

You have in-house technical capacity to run and secure a self-hosted stack, and data sovereignty via self-hosting is a hard requirement.
Your need is simple: a handful of Likert items and a couple of open-text questions, at small scale.
You are running a one-off or pilot rather than an institution-wide, longitudinal programme.
Budget is the binding constraint and analyst time to read comments by hand is genuinely available.

For a single module survey, Microsoft Forms is often the pragmatic, correct answer — do not buy a platform to do what a free form does well.

When it is not — and where a dedicated platform earns its cost

A free tool stops paying off the moment evaluation becomes strategic rather than administrative. Consider a commercial, AI-native option such as Koji when:

You are running evaluation at scale and open-text volume has made manual coding impossible.
You need standardised, bias-aware moderation and comparable, longitudinal cohort reporting across programmes.
You must produce accreditation-ready evidence with a clear audit trail and documented closing-the-loop actions.
Qualitative depth matters — you want to know why satisfaction dropped, not just that it did.

Koji is not free and not open source; it is a commercial, EU-hosted, GDPR-focused platform. It does not compete with LimeSurvey on licence cost — it competes on the analyst weeks it removes, the response quality it raises, and the accreditation evidence it produces. That is the honest trade: free tools minimise spend; a dedicated platform minimises total cost of ownership when qualitative analysis and loop-closure are the real work.

The bottom line

Open source (LimeSurvey, Formbricks) and free proprietary tools (Google Forms, Microsoft Forms, LamaPoll's free tier) are legitimate, well-built ways to collect student feedback, and for small or simple needs they are the right call. But "free" describes the licence, not the workload. If the analysis, response rates and closing-the-loop documentation are where your team is actually stretched, the platform decision should be made on total cost of ownership — not on the line item that reads zero.
