Pros & Cons
Notion
Pros
- Relational databases and nested pages let teams build their own trackers, wikis and project systems without a fixed workflow.
- Docs, knowledge base, calendar, forms and published sites are bundled in one workspace, which can replace several separate tools.
- Business includes AI agents, meeting notes and cross-app Enterprise Search without a separate per-seat AI add-on.
- Enterprise security covers SCIM, audit logs, SIEM and DLP connections, and zero data retention with AI providers.
- Strong review ratings, around 4.6 on G2 and 4.7 on Capterra.
Cons
- Reviewers repeatedly report slow loading and lag in large databases and workspaces.
- Offline support is weak and the mobile app does less than the desktop app.
- Plus includes only an AI trial, so teams that want working AI must pay for Business.
- Since late 2026, AI use beyond the monthly credit allowances pauses unless an admin buys extra credits, and some legacy discounted customers have reported large increases at renewal.
- Teams must design their own structure before it works well for project management, and new users describe the setup as unintuitive.
ONES
Pros
- The free plan covers up to 30 seats and already includes sprint, test, and release management.
- Issue tracking, test cases, and the wiki live in one product, so teams do not have to link Jira, a test tool, and Confluence.
- It can be deployed as SaaS, on-premises, in a private cloud, or air-gapped, which suits regulated industries.
- The vendor reports SOC 2 Type II, ISO 27001, ISO 27018, and GDPR compliance.
- Business and Enterprise plans include tooling to migrate from Jira and Confluence.
Cons
- There are very few independent reviews: about 13 on G2 and 9 on Capterra.
- G2 reviewers mention a learning curve for new users.
- Its third-party integration catalogue looks small next to Jira's or monday.com's.
- Gantt charts and automation need a paid plan, and resource scheduling needs Business.
- Most of the comparison content available online is published by ONES itself.
