Open-Source Attio Alternatives Compared - Relaticle [ Back to blog ](https://relaticle.com/blog) ![Open-Source Attio Alternatives, Ranked by Use Case](https://relaticle.com/storage/ink/01M17KWB9K4XYBFZG8EWVRKM0W.png)Choose Relaticle if its CRM model, self-hosting option, and built-in chat approval flow fit your team. Choose Twenty when custom objects and packaged extensions matter. Consider EspoCRM for traditional CRM modules, with paid extensions included in its cloud plans. Consider Frappe CRM for its Frappe Framework and ERPNext integration. Staying with Attio may be the better choice if its enrichment and workflows meet your requirements. This post compares four open-source options, Relaticle, Twenty, EspoCRM, and Frappe CRM, on license, pricing, AI/MCP capability, and how much work self-hosting actually takes. We maintain Relaticle, so treat that section with appropriate skepticism and check the sources linked throughout. ![Main record list views of Relaticle, Twenty, EspoCRM and Frappe CRM](https://relaticle.com/storage/ink/01M09G8S5MGRSN2CX85R32P68N.png)*Screenshots: Twenty (twenty.com), EspoCRM and Frappe CRM (official GitHub repos); Relaticle from a live workspace.* [](#how-the-four-compare "Permalink")How the four compare --------------------------------------------------------- | CRM | Best fit | License | |---|---|---| | Relaticle | Agent-native teams that want to self-host | AGPL-3.0 | | Twenty | Teams building a custom CRM platform on top | AGPL-3.0 core; check the repository license for enterprise exceptions | | EspoCRM | Teams needing traditional CRM modules and extensions | AGPL-3.0 | | Frappe CRM | Teams already on ERPNext, or that want compute-based pricing | AGPL-3.0 | | CRM | Pricing model | |---|---| | Relaticle | $24/mo flat (or $19/mo billed annually), unlimited users, AI credit packs on top | | Twenty | Pro $9/user/mo and Organization $19/user/mo, both billed yearly; Enterprise from $50k/yr | | EspoCRM | Cloud Basic $15/user/mo (min 3 users), Enterprise $25/user/mo (min 5), Ultimate $69/user/mo (min 10) | | Frappe CRM | Frappe Cloud sites from $5/mo, VM servers from $20-60/mo; unlimited users, billed by compute, not seats | | CRM | AI / MCP | |---|---| | Relaticle | First-party MCP tools plus a built-in AI chat assistant; MCP and chat are available self-hosted; local models need configuration | | Twenty | First-party MCP server with OAuth, documented for Cloud and self-hosted | | EspoCRM | Official Intelligence AI add-on; verify MCP requirements separately | | Frappe CRM | Documented APIs and integrations; verify the intended AI client | | CRM | Self-host effort | |---|---| | Relaticle | Laravel + Filament; app, worker, scheduler, PostgreSQL, and Redis; chat remains credit-metered | | Twenty | Node/NestJS + Redis + Postgres + background workers; core is self-hostable, enterprise-tagged files are license-restricted | | EspoCRM | PHP with a supported database and background jobs; paid extensions for additional features | | Frappe CRM | Python/Frappe Framework + Frappe UI (Vue.js) + MariaDB + Redis; Docker Compose or an easy-install script, free under AGPL-3.0 | *Reviewed September 22, 2026. Pricing sources: [Twenty](https://twenty.com/pricing), [EspoCRM](https://www.espocrm.com/cloud/), [Frappe CRM](https://frappe.io/crm/pricing), and [Relaticle](https://relaticle.com/pricing). Relaticle product claims were checked against its repository.* [](#relaticle-agent-native-self-hostable-flat-priced "Permalink")Relaticle: agent-native, self-hostable, flat-priced -------------------------------------------------------------------------------------------------------------------- Relaticle is a Laravel and Filament CRM licensed AGPL-3.0. Its hosted price is per workspace, with unlimited users. Self-hosting has no software license charge, but infrastructure and operations remain your responsibility. Chat uses credits on hosted and self-hosted installations. Relaticle includes a built-in chat assistant and an MCP server. Its server registers 39 tools as of September 22, 2026. Administrators can configure supported cloud providers or local Ollama models for chat. Model access depends on configuration and the workspace plan. In built-in chat, proposed CRM writes wait for human approval. External MCP writes commit directly under the connected user's authorization. Our [MCP guide](https://relaticle.com/blog/how-to-connect-claude-to-your-crm-with-mcp) explains that distinction. The [self-hosting guide](https://relaticle.com/blog/self-hosting-an-ai-native-crm-in-2026) covers deployment requirements. ![A pending-action approval card in the Relaticle chat interface](https://relaticle.com/storage/ink/01M09G7EYDVKAT2WVZM02PTW35.png) Relaticle does not provide a public app marketplace or a general custom-object importer. Its current scope covers companies, people, opportunities, tasks, and notes. Verify your required integrations and data model before choosing it as an Attio replacement. [](#twenty-custom-objects-and-extensions "Permalink")Twenty: custom objects and extensions ------------------------------------------------------------------------------------------ Twenty supports custom objects and packaged extensions. Its [repository](https://github.com/twentyhq/twenty) documents the source and deployment requirements. Review its [license](https://github.com/twentyhq/twenty/blob/main/LICENSE) before assuming every enterprise feature is available in a self-hosted installation. Twenty's [MCP documentation](https://docs.twenty.com/user-guide/ai/capabilities/mcp) covers Cloud and self-hosted deployments. It supports OAuth or API-key authentication, with permissions derived from the connected user or key role. Twenty's hosted pricing is per seat. Both prices in the overview use annual billing. Its app framework makes it a candidate for teams extending the CRM with custom objects and code. Test the required features before deciding how much setup that will involve. Our [Relaticle and Twenty comparison](https://relaticle.com/blog/relaticle-vs-twenty-an-honest-comparison) examines that choice. [](#espocrm-core-modules-and-extensions "Permalink")EspoCRM: core modules and extensions ---------------------------------------------------------------------------------------- EspoCRM is a PHP CRM with a self-hosted core. Check its [official documentation](https://docs.espocrm.com/) for current server requirements and supported database versions. EspoCRM includes call logging and campaigns. [Workflow automation](https://www.espocrm.com/features/workflows/) requires Advanced Pack for self-hosters and is included in its cloud plans. Price the extensions you need alongside hosting and maintenance. EspoCRM Cloud charges per user with seat minimums, shown in the overview. Its [Intelligence extension](https://www.espocrm.com/extensions/intelligence/) supports OpenAI, Gemini, Claude, and custom OpenAI-compatible providers. Features include summaries, an email composer, and formula functions. We did not verify a documented first-party MCP server during this review. If MCP is required, confirm the integration path before purchasing. That limitation in this review does not mean EspoCRM has no AI capabilities. [](#frappe-crm-resource-based-hosting-and-erpnext-integration "Permalink")Frappe CRM: resource-based hosting and ERPNext integration ------------------------------------------------------------------------------------------------------------------------------------ Frappe CRM uses the Frappe Framework and offers free self-hosting under AGPL-3.0. Its [repository](https://github.com/frappe/crm) and [installation guide](https://docs.frappe.io/crm/introduction/installation) explain the stack and setup. Frappe CRM provides an [ERPNext integration](https://docs.frappe.io/crm/erpnext). It remains a separate application, so enable and test the integration before relying on it. Frappe Cloud pricing is based on hosting resources rather than user count. The starting tiers are in the overview. Frappe CRM's deployment includes Python, MariaDB, and Redis. Relaticle also needs supporting services, so compare the complete operating requirements. We did not establish a documented first-party MCP offering in this review. Check the [current CRM documentation](https://docs.frappe.io/crm/introduction) for integrations relevant to your workflow. [](#migrating-off-attio "Permalink")Migrating off Attio ------------------------------------------------------- Attio offers [view exports](https://attio.com/help/reference/imports-exports/exporting-lists-and-views) and an [admin workspace backup](https://attio.com/help/reference/imports-exports/back-up-your-workspace-data). View exports follow visible attributes and leave enriched values blank. The workspace backup includes notes and other data, but excludes emails. Inspect the export before assuming all customer context will move. Relaticle's import wizard accepts CSV files for companies, people, opportunities, tasks, and notes. Create the required custom fields, then review the column mapping and relationships. Each file may contain up to 10,000 rows and 10MB. The [import guide](https://relaticle.com/help/import) explains the supported fields. Match behavior varies by record type. Companies can match by domain, people by email or phone, and opportunities by Relaticle ID. Notes imports create new records. Keep a record of completed batches before retrying files. Tests on September 24, 2026 found that deleted records can mask live email or domain matches. Stop if an existing record shows Create. Retry using its verified Relaticle Record ID. Check the preview counts and saved relationships before importing a larger batch. ![The Relaticle import wizard's column-mapping step with live sample values](https://relaticle.com/storage/ink/01M09G7GDBH15V03EZ0K6F8KWZ.png) Relaticle also exposes token-authenticated REST endpoints for companies, people, opportunities, tasks, and notes. A migration script can use them when the import needs custom transformations. Relaticle's documented CSV import is a one-time transfer. Plan relationship mapping, repeated runs, and a final cutoff explicitly. Do not assume that importing files creates a continuing two-way connection to Attio.
