Both platforms are open source. But one forces you to buy an entire ERP just to do HR, comes "full of bugs," has a "steep learning curve," and offers "zero accountability." The other does one thing brilliantly: 360° feedback. No bloat, no bugs, no technical debt.
The critical differences between Blik and Odoo HR
| Feature | Blik | Odoo HR |
|---|---|---|
| System Scope | 360° feedback only Does one thing brilliantly |
Full ERP suite Buy 50 modules to use HR |
| Setup Complexity | 5 minutes (docker compose up) Ready immediately |
"Requires technical knowledge" Hours to days configuration |
| Software Quality | Purpose-built, tested Focused codebase |
"Full of bugs" "Even the standard HR module" |
| Learning Curve | < 1 hour onboarding Intuitive single-purpose tool |
"Steep learning curve" "Many options" creates confusion |
| Version Upgrades | Smooth updates Minimal breaking changes |
"Customizations break on upgrade" "Additional effort" required |
| Customer Support | Direct support Responsive team |
"Zero accountability" "Ignored our complaints" |
| Integration Complexity | REST API, clean Works with existing tools |
"Integration issues" "Requires additional development" |
| Performance | Lightweight, fast < 1GB RAM typical |
"Performance slowdowns" "Large data volumes" cause issues |
| Error Messages | Clear, actionable User-friendly feedback |
"Confusing Python errors" Technical messages for users |
| Open Source Model | AGPLv3, fully open All features included |
LGPLv3 + Proprietary Enterprise features paywalled |
Odoo's all-in-one approach creates systemic problems: bugs accumulate, upgrades break customizations, and Python errors confuse end users.
"Even the standard HR module was full of bugs."
— Verified User
"Lack of expertise, zero accountability, and no customer support. Every promised deadline was missed, and they completely ignored our complaints."
— User Review
"When we want to upgrade Odoo to a new version, previous customizations may not be compatible, causing additional effort."
— Enterprise User
One tool, one purpose, done right.
"Zero accountability, no customer support"
If you need a full ERP—sales, inventory, accounting, HR, manufacturing—then Odoo makes sense. It's an integrated ecosystem. But if you just need performance reviews, you're signing up for enormous complexity you don't need. Blik does 360° feedback brilliantly without dragging in 50 modules, version upgrade headaches, and confusing Python error messages.
