Attio vs Twenty (2026): the honest comparison
Updated · June 2026
We implement and run revenue systems on Attio in production, with our name on the result, and we have production experience with HubSpot and Salesforce too. Twenty is the open-source CRM everyone in our world keeps asking about, so this is a fair read on it, not a takedown. The one-line summary you will hear elsewhere is true: Attio is the better CRM today, Twenty is the more interesting bet on tomorrow. Here is why, and which one your team should pick.
The 60-second verdict
Pick Twenty if open source, self-hosting and data ownership are not nice-to-haves but requirements, and you have the engineering capacity to run software you operate yourself. You get an AGPL-3.0 codebase you control, a modern Notion-and-Attio-inspired UI, no licence cost if you self-host, and a CRM you can treat as infrastructure rather than a vendor lock.
Pick Attio if you want a polished, fully managed CRM working today, with deep native integrations, a real API built for AI agents, a stronger reporting path and nothing to operate. You pay a managed-SaaS price and you give up self-hosting, but you get maturity, a real ecosystem and a product that bends to a relationship-led motion in hours.
Our position: we specialise in Attio and do not run Twenty in production, so read us as Attio-leaning but not Twenty-hostile. Twenty's open-source and ownership advantages are genuine, and for the right team they are decisive. For most relationship-led B2B teams that just want the CRM to work now, Attio is the safer call. The rest of this page is the detail.
Attio vs Twenty across 8 criteria
One table, no hedging. Each row gets a winner, and the deep dives below explain the calls that are less obvious than a feature count makes them look.
| Criterion | Attio | Twenty | Winner |
|---|---|---|---|
| Deployment and ownership | Managed SaaS only. No open source, no self-hosting. Data lives in Attio's cloud. | AGPL-3.0 open source. Self-host for free or use managed cloud. You can own the codebase. | TWENTY |
| Data model and flexibility | Typed attributes, first-class relationships, custom objects, lists as views over one shared truth. Mature. | Modern flexible model, custom objects, clean API-first design. Younger but well-architected. | ATTIO |
| Pricing | From about $34 per user monthly, plus free and lower tiers. Fully managed. | Free self-hosted. Managed cloud roughly $9 (Pro) to $19 (Organization) per user monthly. | TWENTY |
| Integrations and ecosystem | Deeper native integrations, app marketplace, strong API and webhooks, n8n, Make, Zapier. | Fewer native integrations, smaller marketplace, API present but ecosystem still young. | ATTIO |
| Automation and AI | AI-first architecture, data-aware native workflows, API designed for agents, verified writes. | Automation and AI present but less developed. Open codebase means you can extend it yourself. | ATTIO |
| Reporting | Native reporting is limited but improving, and the clean model makes API-built dashboards work. | Reporting is earlier-stage and lighter than Attio's. A real gap today. | ATTIO |
| Maturity | Mature managed product, nothing to operate, predictable upgrades and uptime. | Strong momentum, around 40.6k GitHub stars and roughly 600 contributors, but earlier-stage. | ATTIO |
| Who it is for | Relationship-led B2B teams, scaleups and funds that want managed, deep API and AI now. | Developer-led startups and teams with a data-sovereignty or open-source mandate. | DEPENDS |
Score: Attio 5, Twenty 2, one tie. Which tells you almost nothing, because the rows do not weigh the same for your business. If open source is a requirement, the Twenty row outweighs the other seven. Keep reading.
Open source and self-hosting: Twenty's real advantage
This is the row that can settle the whole decision on its own. Twenty is open source under AGPL-3.0, French-founded and YC-backed, with serious developer momentum: around 40,600 GitHub stars and roughly 600 contributors. Self-hosting is free if you run it yourself, which means no per-seat licence and, more importantly, no vendor holding your system of record. For teams with a data-sovereignty mandate, a compliance posture that distrusts third-party clouds, or a philosophical preference for owning the software that runs their business, that is not a feature, it is the point.
Attio offers none of this. It is a managed SaaS with no open-source edition and no self-hosting path. Your data lives in Attio's cloud, reachable through a good API but not under your roof. For most teams that is a non-issue, even a relief, because someone else handles uptime, upgrades and security. But if "we must be able to host this ourselves" is on your requirements list, Attio is disqualified before the comparison starts, and Twenty is the obvious answer.
The honest counterweight: self-hosting is not free in the way that matters. You run the upgrades, the backups, the uptime and the security yourself. That is real engineering time, and it is the cost Twenty's $0 licence hides. Winner: Twenty, decisively, if and only if ownership is a genuine requirement rather than a preference.
Data model and flexibility: two modern takes
Both products reject the old rigid-CRM model, and both are pleasant to use because of it. Twenty's data model is modern and flexible, with custom objects and a clean API-first design, clearly inspired by the Notion and Attio generation of tools. For a CRM this young, the architecture is impressively sane, and because the code is open you can extend the model in ways no closed SaaS allows. If you want a CRM you can shape at the code level, Twenty gives you a foundation Attio never will.
Attio's model is the more mature expression of the same idea. Companies, people and deals are typed records with first-class relationships, custom objects hold whatever your business actually needs (funds, LPs, properties, partner firms), and lists are views over one shared truth rather than copies of it. When a relationship-led motion changes, the model follows in hours, in the UI, without touching code. We run this in production at a PE and M&A fund where the model carries entities a standard CRM cannot.
So the split is real: Twenty wins on "shape it in code," Attio wins on "shape it in minutes without code, and trust that it is battle-tested." For most revenue teams the second matters more. Winner: Attio on maturity and out-of-the-box flexibility, with genuine respect for Twenty's open, extensible foundation.
Pricing and total cost: free to self-host vs managed
On paper this is Twenty's strongest row after open source. Self-hosted Twenty has no licence cost at all. Its managed cloud runs roughly $9 per user monthly (Pro) and $19 (Organization). Attio starts around $34 per user monthly, with free and lower tiers available. Per seat, Twenty is clearly cheaper, and self-hosted it is free. Pricing as of June 2026, check vendor pages before budgeting, both vendors revise pricing.
| Scenario | License basis | Year 1 (10 users) | 3-year total |
|---|---|---|---|
| Twenty self-hosted | $0 licence, you run the infrastructure | About $0 licence + hosting and ops time | About $0 licence + ongoing engineering |
| Twenty Cloud Pro | About $9 per user monthly, 10 users | About $1,100 | About $3,200 |
| Twenty Cloud Organization | About $19 per user monthly, 10 users | About $2,300 | About $6,800 |
| Attio Pro | About $59 per user monthly, 10 users | About $7,100 | About $21,200 |
Two things the table hides. First, self-hosting is not zero: someone provisions servers, applies upgrades, runs backups, handles security and gets paged when it breaks. At a fully loaded engineering cost, a few hours a month quietly outweighs a $19 seat. Second, implementation is symmetric: neither platform configures itself, and a serious build (model, migration, automations, handover) costs the same order of magnitude on either. Ours start at 8,000 EUR. So the real question is not the sticker price, it is whether you would rather pay Attio to run the CRM or pay your own team to run Twenty.
Winner: Twenty on raw cost, with the honest caveat that the self-hosted $0 is the price before the work, not after it.
Integrations, ecosystem and maturity: where Attio is ahead
This is where the gap between a managed product and a fast-moving open-source project shows most clearly. Attio has deeper native integrations, a real app marketplace, reliable webhooks and a clean REST API that the rest of the SaaS world increasingly builds against. Around it, n8n, Make and Zapier fill any remaining gap. In production we run 24 Attio workflows for a fund, including post-meeting extraction and cross-email deduplication, leaning on that integration surface.
Twenty is earlier-stage by definition. It has an API and is building outward fast, but native integrations are fewer, the app marketplace is small, and the surrounding ecosystem of partners, templates and third-party connectors is a fraction of Attio's. The open codebase is a partial answer: what does not exist as an integration, a capable team can build. But "we can build it" is a cost, not a feature, and not every team has the engineers to spend on it.
Maturity follows the same line. Twenty's momentum is real and its trajectory is good, but a managed product with predictable upgrades and uptime is a different risk profile from software you operate yourself at this stage. Winner: Attio on integrations, ecosystem and maturity today, with the explicit note that Twenty is closing distance quickly.
Automation and AI: agents that write to your CRM
Attio was built API-first in the era when software started being operated by software, and it shows. Native workflows are data-aware because they sit on a typed model, the API is designed for agents, and structured writes either fit the schema or fail loudly. In production at the fund, this is not a demo: meeting extraction runs around the clock, a cross-email deduplication pipeline resolves the same human arriving via two addresses into one record, and a re-enrichment pass refreshed 953 stale profiles without a human touching a row. The pattern that makes it safe is verified writes, a second adversarial pass that rejects anything unproven before it reaches the base.
Twenty's automation and AI are less developed today. The building blocks are arriving, but the depth of workflow logic, the agent-oriented API surface and the packaged AI features are behind Attio's. The open-source angle cuts both ways here: you cannot lean on a mature feature set, but you can read and extend the codebase to build exactly the automation you want, which a closed product will never let you do. For a team with engineering appetite, that ceiling is higher even if the floor today is lower.
If your roadmap depends on agents doing real work in the CRM now, the substrate matters more than the slogans. Winner: Attio on automation and AI as they ship today, with Twenty's extensibility as the long-game counterargument.
Who should pick Twenty, and who should pick Attio
Answer these in order. Most teams know which side they are on by the second question.
Is open source, self-hosting or data ownership a hard requirement?
If you must host the CRM yourself, own the codebase, or keep your system of record off a third-party cloud for compliance or principle, that decides it. Attio cannot self-host, full stop. Twenty is built for exactly this. If ownership is a preference rather than a requirement, this question stops counting and the others take over.
Do you have the engineering capacity to run software you operate?
Self-hosted Twenty means your team handles upgrades, backups, uptime and security. A developer-led startup with spare engineering bandwidth absorbs that easily. A revenue team without an owner for infrastructure will feel it as drift and downtime. If nobody wants to own ops, the managed product is not lazy, it is rational, and that points to Attio.
Do you need deep integrations, automation and AI working today?
If your motion depends on a wide integration surface, mature workflows, and agents writing to the CRM right now, Attio is ahead and the gap is real. If you would rather build those capabilities yourself on an open foundation, and you have the people to do it, Twenty's ceiling is higher even though its floor today is lower.
Is your priority the better CRM now, or the more interesting bet on tomorrow?
Attio is the better CRM today: polished, managed, deep, with nothing to operate. Twenty is the more interesting bet on tomorrow: open, ownable, cheaper, improving fast. Relationship-led teams that want results this quarter lean Attio. Teams making a multi-year infrastructure choice with engineering to back it lean Twenty.
Migrating between Twenty and Attio, in either direction
We treat Twenty as an honest comparison point and a tool we can migrate teams to or from, not as something we run in production. Moving from Twenty to Attio usually makes sense when the cost of operating self-hosted software outgrows its savings, when you need integrations, reporting or AI that would take months to build, or when the team that championed self-hosting moves on and nobody is left to run it. The export from Twenty is clean because the model is modern, so the work is in the redesign, not the extraction.
Moving from Attio to Twenty is rarer but legitimate: a new ownership or compliance mandate, a deliberate shift to self-hosting, or a hard line on licence cost. We will not pretend it is painless, you trade maturity and ecosystem for control, but if the mandate is real, the trade is rational and we will run it cleanly. Either way the playbook is the same: field mapping, deduplication, dry runs on a copy, verified cutover, pipeline moving the whole time.
If you are weighing the two, talk to us before you commit. We specialise in Attio and have production experience with HubSpot and Salesforce, so we can give you a fair read on whether Twenty's open-source advantages actually pay off for your team, or whether a managed CRM is the honest answer.
