Pros & Cons
Attio
Pros
- The custom objects and attributes let teams model non-standard processes such as fundraising or partnerships.
- Email and calendar sync builds and enriches contact and company records automatically.
- A Free plan for up to 3 seats and transparent per-seat pricing make it easy to start.
- Pro call intelligence records Zoom, Meet and Teams calls and fills fields from transcripts.
- Developers get API access on every plan, plus webhooks, an App SDK and an MCP server.
Cons
- The native integration catalog is smaller than HubSpot's or Salesforce's.
- Mailbox sending caps make it unsuitable for high-volume outbound SDR teams.
- Plus stops at 10 seats, so the 11th seat forces an upgrade to Pro.
- AI features and workflows draw on credit pools that can run out.
- Reviews say the mobile app has fewer features than the web version, and some report inconsistent support.
Corteza
Pros
- Released under the Apache 2.0 licence, so it can be self-hosted with no licence fees and no vendor lock-in.
- The project says its data model supports most Salesforce standard objects, and users can add their own custom objects.
- Docker-based deployment gives organisations full control over where their data is stored.
- Releases are still being shipped regularly; 2024.9.10 came out in August 2026 and 2026.9 is the latest stable version.
Cons
- The CRM and Service Solution apps were removed from the default deployment in release 2024.9, so the CRM has to be built or installed separately.
- Reviewers say the interface is complex and can be overwhelming.
- According to Prospeo's review, namespace exports leave out workflow references and access-control permissions.
- There are very few independent reviews, and the user community is small.
- Paid support from Planet Crust is expensive.
