Everything you need to know about Blik. If your question isn't answered here, reach out on GitHub.
A 360-degree feedback session is where an employee gets feedback from peers, managers, and if applicable, their direct reports. This gives you a better perspective on their performance and areas to develop. When you pair this with a self-assessment, it shows you where there might be gaps. Maybe you're being too hard on yourself in some areas, or too confident in others. Those mismatches are where the real growth opportunities are.
Reviewers use token-based links, and reports aggregate feedback by category with configurable thresholds. Responses retain a token reference, which may link to an invitation email. Confidentiality depends on invitation method, permissions, thresholds, and feedback content; it is not guaranteed against administrators with database access.
Four templates are included: Professional Skills 360 Review (27 questions in 8 sections), Software Engineering 360 Review (35 questions in 10 sections), Manager 360 Review (17 questions in 7 sections), and 360 Degree Feedback (12 questions in 4 sections). You can also create your own questionnaires.
Yes! The application comes with 4 default questionnaires for different roles and needs, and you can create your own with no restrictions. We have multiple types of answer modes like Likert scales, multiple choice, and free text. The questionnaires can contain multiple segments which work well on mobile devices too.
Yes. Questionnaires and questions you add are yours and stay yours. On the hosted service they live in your organization's own account and are never shared with, visible to, or reused for other customers. Nobody on our side reads your questionnaire content either, unless you explicitly ask us to, for example to help with a support request. Self-hosted installs never send anything to us at all. See the privacy policy and terms.
The report after the questionnaire is finished contains an executive overview that highlights gaps between how you see yourself and how others see you. It spots things like impostor syndrome or undervaluation of your own contributions. You'll see key strengths and weaknesses, plus a bar chart showing self vs others comparison. It also contains a radar chart with the different layers (self, peers, managers) averaged responses. The insights differ per person and questionnaire of course, but in general it should provide actionable insights.
Yes, it's actually implicit. Your progress is saved on every step. Reviewers each have their own unique URL, and this allows them to come back later and continue where they left off safely and easily.
We try to keep anonymity in mind here, so we have a default (changeable) threshold of required answers in order to not be able to take any one response from someone directly. For super small teams you can just set this value to 1 and you will see all answers always. This setting also doesn't apply to managers, who I believe usually provide feedback which you can (should?) act upon.
A report gets triggered either by all invited members finalizing the questionnaire, or by an application admin who closes the report manually. The report itself shows an executive overview plus a detailed in-depth view of all the questions and the aggregated answers per group (self, peers, managers). A report can be generated at will even if some reviewers haven't finished answering all their questions yet. It takes whatever they've filled out so far and leaves the rest of the questions blank.
Yes. Cycles are lightly implemented, meaning there is no enforcing of every reviewee having to be on the same cycle. There are no limits on active cycles and no problem having multiple people in different cycles simultaneously.
You can share a link that generates reviewer tokens or send email invitations. Email invitations can associate a token with an email address, and responses retain their token reference. Shared links do not support email reminders. Explain your invitation method and confidentiality limits to reviewers.
Runs comfortably on a 1 GB VPS for typical team sizes (512 MB minimum).
EU hosting and self-hosting do not automatically establish GDPR compliance. Blik provides export and deletion tools to support your obligations. Your organization remains responsible for lawful processing, configuration, access controls, retention, and compliance processes.
Any Django-compatible database is supported. I recommend using Postgres 15 or higher. The built in standalone Dockerfile uses SQLite to make things easier for anyone to get started from the get go.
Blik supports almost all email providers. We allow you to use your own credentials or even your own Gmail address.
Blik includes a REST API with Bearer token authentication to manage review cycles, reviewees, questionnaires, and reports, plus four HMAC-signed webhook events. Generous limits: 1,000 requests/hour per token; 100/hour for anonymous requests. Open interactive API documentation →
No, you can't find Blik in the app stores, but our web based application works across all modern mobile devices. Benefit is that this also doesn't require installation or setups on user devices.
AGPL. I chose this license because I want others to be able to use, try, and modify Blik the same way I would have wanted to. You can use the app and make changes freely. The main thing is if you host a modified version, you need to make your changes available. This way, if someone adds something useful like LDAP integration, the community benefits too. I'll be honest, licenses can be confusing, but the spirit here is simple. Freedom to use and modify, with the requirement to share improvements back.
Yes, you can. The AGPL license allows you to white label this if you want to. Most things are pretty easy to modify or built in as variables already.
Yes. You get a full account and organization JSON export. This makes it easy to back up your data or migrate to another system if you need to.
This depends on my time and paid users as well as feedback from the community. I hope there will be many community updates, which eventually will lead to other maintainers as well. If you self-host you should probably check in every once in a while. There is no mechanism for this yet. For hosted customers, updates go live immediately after a few minutes when I push them.
Self-hosting is free forever under AGPL license. A single hosted review round is €19 once for up to 10 employees, with no subscription. Managed hosting subscriptions are €49/month for up to 50 employees, or €199/month for up to 200 employees. No per-user fees, no hidden costs, cancel anytime. See full pricing details →
Yes. The Single Round is €19 once and covers a hosted feedback round for up to 10 employees, with no subscription and no charge for reviewers. Review cycles don't expire, reports stay available, and you can start a subscription later from Settings inside your account. See what's included →
The €49/month plan covers up to 50 employees. Enterprise is €199/month for up to 200 employees and adds priority support and an SLA with uptime commitment. Contact us for larger teams.
None. €49 is €49. No setup fees, no per-user charges, no feature restrictions, no surprise renewal increases. The only way your bill goes up is if you grow past 50 employees and need the larger plan.
14-day free trial — credit card required; cancel before it ends and you won't be charged.
All data will be removed after 30 days. Make sure you export your data before canceling if you want to keep it.
Blik is a focused, open-source 360° feedback tool with self-hosting and flat hosted plans. Lattice, Culture Amp, and 15Five offer broader hosted performance suites. Compare the deployment model, feature set, and published contract terms that fit your team. See dated pricing and feature comparisons.
Yes, but we don't have an automated migration tool yet. You'd need to export your data from your self-hosted instance and we can help you import it into a hosted account. If this is something you need, reach out and we'll figure it out.
Probably yes, but we don't have a good import tool and haven't tested this yet. We didn't end up using any other software ourselves, so if you can provide us with sample exports from other tools, we can try to make this work. Reach out on GitHub and we'll figure it out together.
The repo's issues and discussion tabs are where the support will most likely be given and found. I try to keep things documented that are important too. Enterprise customers will receive priority updates and a more direct line if they prefer.
Not officially yet, but if you're an Enterprise customer or have a specific need, reach out. I'm happy to help with custom questionnaire design, onboarding, or integration work on a case-by-case basis.
Not out of the box yet, but the REST API makes this possible. You'd need to build a small integration script that syncs employee data from your HRIS to Blik. If there's demand for specific integrations, we can prioritize building them. Let us know what you need.
Not yet. Right now, the GitHub Discussions is the best place to ask questions, share use cases, and connect with other Blik users. If the community grows, we'll set up something more real-time.
Check out our documentation on GitHub or start a discussion. The community is friendly and I respond quickly.
