ReviewNB review
A focused notebook review tool for teams working in GitHub or Bitbucket.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ReviewNB is a code review and collaboration tool for Jupyter notebooks. It is designed for data science, machine learning, education, and open-source teams working with notebook-based repositories. Reviewers can inspect rich diffs for notebook commits and pull requests, comment on cells or lines, and manage conversation threads with resolution statuses. The product is available as a hosted service or as a self-hosted deployment.
Pricing is structured around a free plan and paid tiers. Free is intended for open-source and education use, with academic and open-source use free forever; general users receive a 14-day trial followed by 10 free PRs. Team costs $79 per month for up to 10 users and includes unlimited private and public repositories. Business costs $249 per month for up to 30 users with the same repository allowances. Enterprise supports 30+ users with priority support, ACH invoicing, and custom terms of service. Self-Hosting provides a Docker distribution and works with GitHub Enterprise and GitHub Cloud.
The product’s strongest fit is notebook-specific review: cell-level discussion, notebook diffs, email notifications, and comments posted directly to GitHub and Bitbucket pull requests keep review activity close to the repository workflow. An optional Chrome extension supports GitHub integration, while JDoc provides standalone notebook commenting. ReviewNB should suit teams whose review process centers on Jupyter notebooks and Git-based collaboration. Teams looking for automated analysis, AI-generated review feedback, custom rules, security features, or analytics should choose a different code review product.
