CRM

twenty60.8k★

Twenty is a CRM you shape like a database: custom objects and fields, kanban and calendar views, email sync, workflows, AI agents and a full API. It's a serious open source swap for the CRM side of Salesforce or HubSpot, and self-hosting the core is free under AGPL-3.0. Self-hosting is easier than its reputation. A one-line install script brings up four containers (server, worker, Postgres, Redis), and the docs ask for at least 2GB of RAM. The real work is keeping up: Twenty shipped three minor releases in five days this October, and you own every upgrade. The free self-hosted tier stops short of SSO, row-level permissions, audit logs and custom AI models. Those need Organization at $19/user/month billed yearly ($25 monthly), cloud or self-hosted. Cloud Pro is $9/user/month yearly ($12 monthly) after a 30-day trial, and Enterprise starts at $50k/year. Solo and small teams: free self-hosted, or cloud Pro. Teams needing SSO: Organization. The catch: a CRM holds your most sensitive data, and Twenty's 2026 advisories include a critical SQL injection and a bug that showed any workspace member the plaintext IMAP, SMTP and CalDAV passwords of connected accounts. Both are fixed, so don't let upgrades slide.

Comp AI CRM12.0k★

Comp AI CRM flips the usual setup: an AI agent runs on its own schedule and the CRM is where it keeps notes. It reads your team's inbox, turns new people into contacts, enriches companies and books its own follow-ups, with an Agent tab on each record showing its reasoning. It's MIT, from Comp AI, the compliance-software company. Self-hosting means three deployments plus Postgres: a Next.js app, a NestJS API and the agent. You need Bun, Docker and a Google or Microsoft OAuth app, and it's single-tenant by design. It leans hard on Vercel: the model runs through Vercel's AI Gateway, keyless only when deployed on Vercel. No paid tier, no hosted version. The model calls cost money, though: AI Gateway bills provider list prices past a $5 monthly credit, and LinkedIn and company data come from Context, free for 1,000 credits a month, then $19/month. Solo and small sales teams: free software, budget for tokens. Bigger orgs: this isn't Salesforce. The catch: it's young and has gone quiet. The last release shipped August 21 and the main branches haven't moved since. It also sends anonymous telemetry daily unless you set CRM_TELEMETRY_DISABLED=1. Test it on copied data first.

SuiteCRM5.9k★

SuiteCRM is the most mature open source CRM available. Originally forked from SugarCRM when Sugar went closed source, it now ships under AGPLv3 with a full sales pipeline, contact management, marketing automation, and reporting stack. Salesagility (the maintainers) released version 7.15.1 this March, and the repo shows nearly 17,000 commits and 230 releases. This isn't a hobby project. Self-hosting is the standard LAMP-ish stack: PHP 8.1 through 8.4, Apache (recommended) or IIS, and MySQL/MariaDB or SQL Server. Plan a few hours for a clean install and ongoing time for patches. The customization surface is large; SuiteCRM accommodates everything from solo consultants tracking deals to mid-market companies running full sales operations. Solo and small teams: self-host. The savings versus Salesforce at any team size are real, and the data stays yours. Large teams with limited PHP ops capacity: SuiteCRM Hosted (the official managed offering) plus SuiteASSURED support is the practical path. Enterprise teams currently on Salesforce: this is a real migration. Possible, but multi-quarter. The catch: the UI looks like 2015. The data model and features are competitive, but the interface is dated next to HubSpot or modern CRMs like Attio. If your sales team cares about the look as much as the function, factor that in.

erxes4.1k★

erxes wants to be your entire business operating system. CRM, helpdesk, project management, marketing automation: it bundles what most companies stitch together from HubSpot, Zendesk, and Linear into one self-hosted platform. The plugin architecture is flexible. Pick what you need, skip what you do not. GraphQL federation under the hood means the pieces talk to each other without turning into a monolith. The community core covers sales pipelines, contacts, inbox, segments, and automations. That is a real CRM out of the box. Compare that to SuiteCRM or Twenty, which focus narrower. erxes swings wider, more like an open source Salesforce than a simple contact tracker. The catch: the best plugins are Enterprise Edition only. Accounting, content management, team tools, and several vertical modules sit behind a commercial license. Self-hosting requires MongoDB, Redis, and a microservices stack that will keep your ops team busy. The "experience operating system" ambition means complexity is baked in from day one.

Frappe CRM4.0k★

Frappe CRM tracks leads, deals, and every conversation around them, with one difference from the SaaS incumbents that matters: pricing is per server, not per seat. The software is AGPL and complete, no feature gating, from the same team behind ERPNext. Calls, emails, notes, and tasks land on one activity page per deal instead of scattered tabs. Self-hosting means operating a full Frappe stack: MariaDB, Redis, background workers, a scheduler. Docker Compose gets you running, but upgrades go through Frappe's bench tooling and you're pinned to matching framework versions. Fine with someone who does ops; not a drop-a-binary situation. Frappe Cloud hosts it from $5/mo with unlimited users, which is the number to hold against HubSpot's per-seat math. Solo: overkill unless you're already in the Frappe ecosystem. Small sales teams: this is where per-seat SaaS pricing hurts most and where the switch pays off fastest. Teams already on ERPNext: the integration is native, use it. The catch: you're adopting a framework, not just a CRM. Customization means learning Frappe's DocType model, and AGPL needs a legal read if you're embedding it in something you sell.

EspoCRM3.6k★

EspoCRM is the cleaner-looking open source CRM. AGPLv3, modern single-page-app frontend, and an active release cadence with 22,000+ commits. The latest 9.3.6 dropped two weeks ago. Where SuiteCRM feels like a 2015 enterprise tool, EspoCRM feels like a 2023 SaaS product without the SaaS bill. Self-hosting needs PHP 8.3-8.5 and either MySQL 8, MariaDB 10.3+, or Postgres 15+ (notable: most PHP CRMs are MySQL-only; EspoCRM ships Postgres support). The setup is meaningfully simpler than SuiteCRM. Customization is via the built-in admin UI: custom entities, fields, layouts, and workflows configured without touching code. Solo and small teams: this is the friendliest path into an open source CRM. The UI doesn't embarrass you in front of clients, the Postgres option is useful if you already run it for other things, and the AGPLv3 license keeps the data yours. Large teams: capable but lighter on advanced enterprise features than SuiteCRM. Evaluate both before committing. The catch: there's no official hosted version. EspoCRM offers professional services (install, customization, support) but no managed cloud. If you want SaaS pricing with somebody else running PHP, SuiteCRM Hosted is a better fit. EspoCRM is for teams comfortable running their own infrastructure.

CordysCRM2.9k★

CordysCRM is a self-hosted CRM you fully own, built for teams that don't want their customer data living in Salesforce's cloud. It covers the whole sales lifecycle, lead capture, pipeline, deals, through to payment collection, with role-based permissions and built-in BI dashboards. Picture Salesforce's core workflow running on your own server, with AI sales-assist features layered on top. Self-hosting is the whole point and it's a moderate lift: it's a Java application you deploy and maintain, with a database to back up and keep patched. Once it's running, your customer records, every contact and deal, sit on infrastructure you control. That's the trade for skipping per-seat SaaS pricing. Small teams and growing companies tired of Salesforce or HubSpot seat fees are the target. Solo founders may find it heavier than they need, a lighter tool would do. Teams with the ops capacity to run a Java app and the motivation to own their data get the most value, especially in markets where data residency is a hard requirement. The catch: it's open core under a FIT2CLOUD license, not pure open source, so the most advanced features and commercial use route through paid licensing. The project and docs lean toward the Chinese market, so expect some rough edges in English. And a CRM is sticky, migrating in and back out is real work, so test it hard before you commit your pipeline to it.
