Odoo is a full ERP that includes HR and performance management alongside sales, inventory, and accounting. Blik is a focused, open-source 360° feedback tool. If you need reviews only, Blik does that with four research-backed questionnaires; if you want an integrated business suite, Odoo is the broader platform.

The two products solve different problems. Odoo is an integrated business suite; Blik is a single-purpose 360° feedback tool. The right choice depends on whether you need the wider platform.
What Blik doesn't cover: no ERP modules, no SSO/SAML, no native HRIS connectors, and no native mobile app (it uses responsive web design).
If your business needs an integrated ERP with HR included, Odoo is worth evaluating for its connected apps and shared business workflows.
If you need a full ERP — sales, inventory, accounting, HR, manufacturing — Odoo makes sense as an integrated ecosystem. If you just need performance reviews, Blik covers that in a focused tool without the wider platform, with a REST API and webhooks for custom integrations. Both are legitimate depending on the scope of what you're building.
Blik's confidentiality depends on invitation method, permissions, reporting thresholds, and response content. Reviewer email addresses can be stored with invitation tokens linked to responses; category-aggregated reporting is not an administrator-proof anonymity guarantee.

If performance reviews are what you need, you don't have to adopt a full ERP to run them. Blik is a dedicated 360° feedback tool with token-based access, category-aggregated reports, automated insights, and self-hosted or flat-rate EU hosting.
