Working with product teams can be frustrating. Files are spread across different tools. Feedback gets buried in email threads. Design reviews feel slow and disorganized. And by the time everything is approved, you’re already behind schedule.
That’s why many teams use CoLab. It helps share designs, collect feedback, and keep everyone on the same page.
But if CoLab isn’t quite working for you, whether it’s because of pricing, missing features, or limited integrations, it might be time to look at other tools.
In this article, we’ll review five alternatives to CoLab worth trying in 2025. Each one offers something different to help your team move faster and work better together.
What Is CoLab Software?

CoLab is product collaboration software designed to support engineering teams during design reviews. It helps collect and organize feedback from subject matter experts and connects that feedback directly to the design files.
This allows teams to keep track of what was said, even if some reviewers aren’t present during live meetings. The system also makes it easier to search and use past review data, which can help teams make more informed decisions in future projects.
The software includes AI features that assist with routine design checks. These tools review models or drawings and create comments based on set checklists. CoLab can connect with common PLM and CAD platforms and supports over 30 file types.
This makes it possible to review different kinds of CAD files within the same system, whether the team is working internally or with outside partners.
Why Look for CoLab Alternatives?
CoLab helps teams manage design reviews and feedback, but it might not be the right fit for everyone. Depending on your team size, tools, or workflows, you may find that another option works better for your needs.
Below are a few reasons why some teams explore alternatives to CoLab.
May Be Too Complex for Smaller Teams
CoLab is built for teams with structured engineering processes and detailed reviews. If your team is small or your review process is more casual, the platform may feel like too much.
You might prefer something easier to set up and use, without the extra steps or features that aren’t relevant to your workflow.
Limited Integration With Other Tools
While CoLab works well with major CAD and PLM systems, it may not connect easily with other tools your team uses every day, like task managers, cloud storage, or communication apps. If smooth integration with a wider toolset is important to your workflow, this could be a limitation.
Cost May Not Fit Your Budget
For smaller companies or teams with tight budgets, CoLab’s pricing might feel too high. If you only need basic review tools or are just getting started, there are other platforms that may offer the core features you need at a lower monthly cost.
Workflow Might Need More Flexibility
CoLab has a structured approach to how reviews and feedback are handled. That can be helpful for some, but others may need more flexibility in how tasks are managed or how files are shared.
If your team works differently or needs more control over the process, another tool might be a better match.
