The best open-source CRMs

EspoCRM has been around long enough to have stopped chasing fashions, and its pricing reflects a philosophy the rest of this category has largely abandoned: you get everything, and what you pay for is scale. All three hosted tiers advertise the full feature set and every extension. What separates Basic from Ultimate is file storage and how many records you are allowed to keep.

That makes the arithmetic unusually simple. Basic is US$15 per user per month with a hundred thousand records and a three-user minimum; Enterprise is US$25 with ten million; Ultimate is US$69 with no limit. Underneath sits the open-source edition, which you can install on your own server and run without a licence fee.

The cost is the seat minimums, which make this a poor answer for somebody working alone: the cheapest way into the vendor's cloud is three seats whatever your headcount. Self-hosting removes that and replaces it with an operational burden you carry yourself. Integrations are respectable rather than remarkable, and an external API is on every tier. On data control it is as strong as software gets, because you run it on your own hardware, and the value case is simple arithmetic.

SuiteCRM is what happens when a commercial CRM is forked and then maintained in the open for more than a decade. It is a full business system rather than a light one — accounts, opportunities, quotes, campaigns, workflow and reporting are all present — and the whole thing is available under an open-source licence at no cost per seat.

That combination is why it scores where it does on value. Nothing about your customer records has to leave hardware you own, the source is there to read, and the ceiling on users is whatever your server can carry rather than whatever a price list says. The 8.x line is still shipping point releases, so this is a maintained project rather than an archived one.

The cost is the first day. Setup is a server installation with a database behind it, not a signup form, and the interface carries the accumulated design decisions of a product that started in the 2000s. A small team without anyone comfortable administering a server will find the free licence is the cheap part, and the newer open-source projects in this field are considerably easier to stand up.

Odoo draws its free line somewhere nobody else does. Rather than capping users or records, it gives you one application at no cost for an unlimited number of people. If the application you pick is the CRM, a company of forty can run its pipeline on Odoo Online without paying anything, which is a genuinely different offer from the two-user free tiers elsewhere in this field.

Above that, pricing is per user for all applications together: EUR 19.90 a month on yearly billing for Standard, or EUR 29.90 for Custom, which adds on-premise deployment, the Studio builder, multi-company support and an external API. The core is open source, so self-hosting is a real route and the data can sit on machines you control.

On value that is hard to argue with: an unlimited-user CRM at no cost. The catch is that the free tier is a doorway rather than a destination. The moment a second app is useful — invoicing, helpdesk, projects, all of which sit right there — the price becomes per user for everything, and the step is deliberate. There is also the configuration burden that comes with any suite: this is more product than a small sales team needs, and making it fit takes work that a single-purpose CRM does not ask for.

Twenty is the open-source CRM that most obviously wants to be used by people who write software. It is licensed under the AGPL, the repository is busy, and the documented way to run it yourself is a Docker Compose file rather than a support ticket. If your objection to this category is that your customer data lives on somebody else's machine, this is the entry that answers it directly.

The pricing inverts the usual shape. Full customisation, custom apps and workflow automation are all on the cheapest paid tier at US$9 per user. What the second tier at US$19 adds is governance rather than capability: row-level permissions, single sign-on, and a custom domain.

On scale headroom it is better equipped than its age suggests, with row-level permissions, single sign-on and an audit log. The tradeoff is the one you would expect of a young project. Integrations are thin — the catalogue does not approach what a decade-old vendor accumulates — self-hosting is only free if your time is, and above the two published tiers sits an enterprise arrangement starting at fifty thousand dollars that is negotiated rather than listed. What you get in exchange is unusual control: run it on hardware you own, read exactly what it does with your records, and take the database with you whenever you want.

Heli is a deliberately small product and makes no attempt to be otherwise. It is a contact list with a memory: people and the companies they work for, a log of every call and email, and projects you can move those people through in stages. The interface is built for the keyboard, with single-key navigation and a shortcut for everything.

The unusual part is where the data sits. You choose a region — the US, the EU, Asia-Pacific — or you keep it on hardware you own, which the AGPL-3.0 licence and the public repository make a real option rather than a promise. Full CSV export is documented, and the vendor states there is no tracking, no advertising and no third-party access.

The cost is scale and evidence in roughly equal measure. There is no team tooling to speak of, no published catalogue of integrations, and nothing approaching the automation that larger products sell. The hosted service is documented as free for one person during beta, and what it costs after that is not published, which is the one place this entry falls short of the standard this site applies everywhere else. And it is new enough that almost every claim above rests on the vendor's own documentation, with no independent coverage to check it against.

Krayin is an open-source CRM built on Laravel, and that framework choice is most of its argument. Extending a CRM usually means learning the vendor's own extension model; here it means writing PHP in a framework that a very large number of working developers already use, against a codebase you can read in full.

What follows from that is data control of the strongest kind available: records on hardware you own, with no third party holding a copy. There is no licence cost, the application runs on infrastructure you provide, and customer records never leave machines you own. For a development shop that wants a CRM shaped precisely to a process, starting from readable code in a familiar framework is a shorter path than configuring somebody else's product.

The cost is everything a vendor normally absorbs. No hosted plan is published, so provisioning, updates, backups and security are yours from the first day. It is also younger and less proven than the established open-source projects in this field, with a smaller community and less accumulated documentation, which matters most at exactly the moment something breaks.
