Koji vs LimeSurvey for Course Evaluation (2026): A Fair Comparison
LimeSurvey is a mature, GDPR-friendly open-source survey platform many European universities already self-host. Koji is a purpose-built, AI-native course-evaluation tool. Here is an honest, evidence-based comparison for QA directors and procurement teams.

Short answer: LimeSurvey is a mature, open-source survey platform that thousands of European universities already self-host for full data sovereignty and zero per-response licensing. For a department with the technical staff to run it, LimeSurvey is a genuinely strong, GDPR-friendly choice for traditional Likert-plus-comment course evaluations. Koji is a different kind of tool: a purpose-built, AI-native course-evaluation platform that replaces the static questionnaire with an AI-moderated conversational interview, then automatically themes the open-text at scale and tracks closing-the-loop actions. If your strategy is "send the standard questionnaire, export to SPSS, and have staff read the comments," LimeSurvey does that well and cheaply. If you want richer qualitative evidence, automated thematic analysis, and accreditation-ready documentation without a manual coding effort, Koji is built for that.
This comparison is written for the people who actually procure evaluation software — QA directors, heads of teaching and learning, institutional-research leads, and procurement — and it tries to represent LimeSurvey fairly, because honesty is what earns trust with an evidence-driven audience.
At a glance
| Dimension | LimeSurvey | Koji |
|---|---|---|
| Product type | General-purpose survey platform (open source) | Purpose-built course-evaluation platform (AI-native) |
| Core method | Static questionnaire (Likert + open text) | AI-moderated conversational interview |
| Licensing | Community Edition free (self-hosted); cloud plans tiered by response volume | Commercial SaaS, EU-hosted |
| Open-text analysis | Manual — staff read and code comments | Automatic thematic analysis at scale |
| Follow-up probing | None (fixed question flow) | Yes — AI probes vague or thin answers |

What LimeSurvey is — and where it is genuinely strong
LimeSurvey is one of the most widely deployed open-source survey tools in European higher education, and for good reasons. It is released under an open-source licence, so the Community Edition can be self-hosted at no licence cost with full access to the source code. Cloud plans are available and, as of publication, are tiered by response volume (a free tier with a small monthly response cap, then paid Basic, Expert, and Business tiers); for exact current pricing you should check LimeSurvey directly, as published figures change.
On capability, LimeSurvey is mature: 30+ question types, branching and skip logic, an ExpressionScript engine for complex conditional logic and piping, support for 80+ languages, and clean exports to SPSS, R, Stata, Excel, CSV, and more. For data protection it offers EU hosting with a choice of data centre, anonymised responses, configurable IP/referrer logging, and consent checkboxes — all of which matter for GDPR. Many institutions integrate it with their existing LDAP/SSO so students authenticate with their normal university credentials.
The single biggest argument for LimeSurvey is data sovereignty at zero licence cost: when you self-host the Community Edition, response data never leaves a server you control. For a privacy-conscious institution with capable IT, that is a powerful position.
Where LimeSurvey leaves gaps for course evaluation specifically
LimeSurvey is an excellent general survey tool, not a course-evaluation tool, and the distinction matters once you run evaluation at institutional scale:
- You build the evaluation cycle yourself. Item banks, per-course scheduling, reminder cadences, hierarchical reporting by programme and faculty — none of that is out of the box. As LimeSurvey itself and independent reviewers note, out-of-the-box functionality is limited compared with purpose-built tools, and meeting specific requirements can mean plugins or custom development.
- Self-hosting carries an operational burden. Reviewers consistently flag that running LimeSurvey means installing and patching it, managing MySQL/PHP and server configuration, scheduling cron jobs, and handling backups. That is real staff time, and it shifts the GDPR accountability for hosting onto you.
- Qualitative analysis is manual. LimeSurvey collects open-text comments but does not theme them. At scale, that means either a large hand-coding effort or — as happens at many institutions — comment boxes that simply go unread.
- No conversational probing. A fixed questionnaire cannot follow up on "the course was fine" or "the labs were confusing." Whatever the student types is all you get.
- No built-in closing-the-loop. Tracking what changed in response to feedback — the evidence accreditors increasingly want — is a separate, manual process.
What Koji does differently
Koji is designed around the parts of evaluation that traditional survey tools handle weakly:
- AI-moderated conversational interviews. Instead of a Likert grid, each student has a short, standardized conversation. When an answer is vague, the AI asks a neutral follow-up — so you capture why, not just a rating.
- Automatic thematic analysis. Open-text is themed at scale, so a programme lead sees the recurring issues across hundreds of students without hand-coding a single transcript.
- Bias-aware, standardized moderation. Every student gets a consistent, neutrally-worded interview, which standardizes the collection process across courses and cohorts.
- Formative and summative. Run a lightweight mid-module check and the end-of-term evaluation from the same engine.
- Closing-the-loop and longitudinal reporting. Action tracking and cohort-over-cohort trends produce the kind of documentation that maps directly onto accreditation expectations (see our guides on ESG/ENQA evidence and closing the feedback loop).
- EU/GDPR data handling. Koji is EU-hosted and acts as a GDPR processor under a data processing agreement.
Koji runs on the same AI interview engine that powers the main Koji platform at koji.so for general customer and user research — so the conversational, automatically-analysed approach is proven beyond education.
Detailed comparison

When LimeSurvey is the better choice (honestly)
LimeSurvey is the right call when:
- You have in-house IT and want full, self-hosted data sovereignty at zero licence cost — and you are comfortable owning patching, backups, and uptime.
- Your evaluation is deliberately quantitative — Likert plus light comments — and staff have the capacity to read the open text that comes in.
- You need a single general-purpose survey stack for many uses beyond course evaluation (research surveys, event feedback, internal questionnaires) and want to run it all on one self-hosted platform.
- You are budget-constrained but technically capable, and the trade-off of staff time for software cost is one you would happily make.
In those situations, paying for a purpose-built tool may be solving a problem you do not have. We would rather you knew that.
When Koji is the better choice
Koji earns its place when the qualitative half of evaluation is where your value is — when you need to know why students rate a module the way they do, when comment volume already exceeds what staff can read, when accreditors want documented closing-the-loop evidence, and when you would rather not run server infrastructure to get there. If "we collect feedback but never really analyse the comments or act on them visibly" describes your current state, that is the gap Koji is built to close.
GDPR and data sovereignty
Both tools can be run compliantly. LimeSurvey's self-hosted Community Edition is the gold standard for sovereignty — data sits on infrastructure you own — but that also means the compliance and security accountability for hosting is entirely yours. Koji is EU-hosted and operates as a GDPR processor under a DPA, which moves the hosting-security burden to the vendor while keeping data in the EU. Neither model is universally "more compliant"; they distribute responsibility differently. See anonymity vs confidentiality under GDPR for how this plays out in evaluation design.
Bottom line
Choose LimeSurvey if you want a free, self-hosted, GDPR-sovereign, quantitative-first survey platform and you have the technical capacity to run it. Choose Koji if you want conversational depth, automated thematic analysis, and built-in closing-the-loop evidence without operating infrastructure. Many institutions will find LimeSurvey perfectly adequate for the numbers and Koji decisively better for the narrative — and the honest answer is that the right tool depends on which half of evaluation you are trying to improve.
