Key Differences

Platform Scope

Atomic CRM: Atomic CRM is a focused CRM toolkit: sales pipeline, contacts, tasks, and data import/export.

Corteza CRM: Corteza is a low-code platform where CRM is one module among a Unified Workspace, Enterprise Messaging, and a general-purpose low-code app builder for records-based business apps.

A broader platform can replace more tools at once, but a focused CRM is often simpler to deploy and maintain.

Managed Hosting Availability

Atomic CRM: Atomic CRM offers first-party managed plans from Marmelab: Starter at €25/month (1,000 contacts, 1GB storage) and Team at €50/month (10,000 contacts, 10GB storage), in addition to free self-hosting.

Corteza CRM: Corteza has no first-party managed-cloud pricing page; hosted instances are offered only by third parties such as Planet Crust.

Teams without infrastructure resources need a first-party managed option rather than relying on third-party hosts.

AI Assistant Integration

Atomic CRM: Atomic CRM includes an MCP Server out of the box for connecting AI assistants to CRM data.

Corteza CRM: Corteza's facts don't document an MCP server or AI integration.

MCP support lets AI assistants query and act on CRM data directly, a growing requirement for AI-augmented workflows.

Governance Model

Atomic CRM: Atomic CRM is maintained by Marmelab as the primary maintainer, without a foundation structure documented.

Corteza CRM: Corteza's code is contributed to the Commons Conservancy Software Foundation, so access cannot be revoked by a single vendor, under the Apache 2.0 license.

Foundation governance reduces single-vendor lock-in risk for organizations planning long-term deployments.

Technology Stack

Atomic CRM: Atomic CRM is built on React, TypeScript, Shadcn UI, and Supabase (Postgres-based backend).

Corteza CRM: Corteza's stack details aren't specified beyond being deployable via Docker.

Teams that want to extend or self-host the code need to know what stack they'll be working in.

Pros & Cons

Atomic CRM

Pros

  • Fully open source with complete source-code transparency
  • Self-hostable for full data ownership and no vendor lock-in
  • Modern, actively maintained tech stack (React, Supabase, TypeScript)
  • AI-assisted customization via Claude Code integration

Cons

  • A newer product (2024) with a smaller ecosystem than established CRMs
  • Self-hosting requires technical setup and ongoing maintenance
  • Some enterprise features like SSO are tied to managed/paid plans

Corteza CRM

Pros

  • Free and open source with no per-seat licensing fees, unlike Salesforce, HubSpot, or Zoho CRM
  • Fully customizable data model, fields, and workflows via the underlying Corteza low-code platform
  • Includes built-in sales automation, lead scoring, and forecasting out of the box
  • Self-hosting keeps customer and sales data entirely within the organization's own infrastructure

Cons

  • Requires self-hosting and DevOps capability, unlike turnkey SaaS CRM products
  • Smaller feature depth and third-party marketplace than dedicated commercial CRMs like HubSpot or Salesforce
  • Fewer native integrations with popular marketing and support tools out of the box
  • Smaller community and documentation base than mainstream CRM platforms

Use Cases

Choose Atomic CRM: Teams that want a modern, focused sales CRM (Kanban pipeline, contacts, tasks) built on a well-documented stack, with the option of Marmelab's managed hosting starting at €25/month for up to 1,000 contacts.
Choose Corteza CRM: Organizations that want to build a broader set of low-code business apps beyond CRM, including internal messaging and a unified workspace, under an Apache 2.0 license managed by the Commons Conservancy Software Foundation.
Need both: Running both simultaneously in production would be redundant since they compete directly as self-hosted CRM options; a technical team might instead pilot both side by side, Atomic CRM if they already run Supabase, or Corteza if they want a broader low-code platform, before standardizing on one.

Atomic CRM

  • Customizable self-hosted CRM — Technical teams self-host and modify Atomic CRM to fit their exact sales process.
  • Managed CRM without lock-in — Small businesses use the managed hosting option to avoid running infrastructure while retaining data ownership.

Corteza CRM

  • Free Self-Hosted CRM — Small and mid-sized businesses adopt Corteza CRM to get full CRM functionality without recurring per-seat SaaS fees.
  • Customizable Sales Pipeline Management — Organizations with non-standard sales processes use Corteza CRM's low-code customization to tailor fields and workflows to their exact process.
  • Salesforce Replacement — Organizations looking to move off Salesforce for cost or data-control reasons adopt Corteza CRM as an open-source, self-hosted alternative.
