JSONCRM vs Attio
The short version: Attio is a genuinely good, well-funded SaaS CRM — flexible data model, polished UI, real email/calendar sync and enrichment. You pay for it per seat, and since 2026 also per AI credit. JSONCRM is the opposite trade: no cloud, no seats, no credits — your pipeline is JSON files in a git repo, and your agents are unmetered because they run on your own tools. Want a hosted product for a sales team? Attio. Want a free, open-source Attio alternative you own outright, agent-first? JSONCRM.
Attio sits at the head of the "AI-native CRM" wave — the category you've probably seen advertised. It earned that position: the data model is unusually flexible, the interface is fast, and for a team that wants a managed product with email sync, enrichment, and dashboards out of the box, it's a reasonable buy. This comparison isn't "Attio bad" — it's two different answers to "who owns the system of record, and what does an agent cost to run against it?"
Seats and credits vs a git repo
After its July 2026 repricing, Attio's paid plans run $35/seat/month (Plus, annual) and $79/seat/month (Pro), with Enterprise quoted custom — and "Ask Attio" plus data enrichment now draw from two refilling credit pools (a per-seat allowance and a per-workspace pool), with paid top-ups beyond them. Multiple 2026 buyer guides flag the same friction: the sticker price understates real spend, and budgeting the credit system is hard.
JSONCRM's pricing model is a file system. Unlimited records, unlimited "seats" (whoever collaborates on your repo), unlimited agent calls — the meter that exists is your own LLM bill, which you'd pay anyway. If a five-person team on Attio Pro spends ~$4,700/year before credits, the equivalent line item here is $0.
The agent story: credits vs files
Attio's AI ("Ask Attio", automated enrichment) is good — and metered. JSONCRM's agent access is
structural: the CRM is JSON, so any LLM reads and writes it natively, with a CLI and a first-party
MCP server on top, and --dry-run previews on every write. You bring the intelligence
(Claude, Cursor, your own stack); the CRM brings the substrate. No per-question economics, no
vendor deciding which model you use.
Ownership and exit
Attio's export gives you your data; JSONCRM is your data. There's no account to close and nothing to export — the day you stop using the tool, you still have a perfectly usable git repo of structured pipeline history. The flip side is honest: Attio gives you a hosted, backed-up, multi-user product with granular permissions today, and JSONCRM gives you files, git, and a local web UI. Teams that need the former should buy it.

| AI agent usage | Unmetered — CLI + MCP + dry-run; you pick the model | "Ask Attio" + enrichment, drawn from credit pools |
| Email / calendar sync | Not built in — agents/scripts read files, PRs land changes | Built in, polished |
| Data model | Flat records defined by you + .crm.json |
Flexible custom objects, relations, GUI builder |
| Team collaboration | Git — branches, diffs, pull requests | Workspaces, roles, shared views |

🏢 Choose Attio if…
- You want a hosted product with support, backups, and uptime you don't think about
- Non-technical sellers need polished email/calendar sync and enrichment today
- You need custom objects and permissions for a real sales org
- Per-seat budget is approved and credit-based AI is acceptable
⚡ Choose JSONCRM if…
- $0 spend matters, or procurement doesn't want another SaaS contract
- Your pipeline should live next to your code, reviewable in git
- AI agents are the primary operators — unmetered, model-agnostic
- You want an open (AGPL) system with a commercial-licensing path
A fair closing note
These tools rarely compete for the same buyer. Attio is built for sales teams that want to buy a working product; JSONCRM is built for people who'd rather run their pipeline the way they run their codebase. If you're an Attio customer curious about the file-based extreme, the quickstart takes about a minute and won't touch your Attio workspace.
Attio alternative — common questions
Is there a free alternative to Attio?
Yes — JSONCRM is a free, open-source Attio alternative (AGPL-3.0) with no seats and no credits. Attio's own free tier covers 3 seats with monthly AI-credit allowances; beyond that you're on per-seat pricing. JSONCRM's cost model is your existing infra: a git repo and the LLM you already pay for.
Is JSONCRM a good Attio alternative for small teams?
For developer-led and agent-first teams, yes — especially if you want the pipeline reviewable in git and your AI agents working through a first-party MCP server or the CLI. If your team needs hosted email/calendar sync, enrichment, and permissions for non-technical sellers today, a hosted SaaS CRM like Attio is the more honest answer.
How do I move my data out of Attio (or in)?
Attio provides data export. Because JSONCRM records are flat JSON objects, migrating is mostly mapping your exported columns to fields, dropping them into leads.json, and running jsoncrm validate. Moving away from JSONCRM is even easier — there's nothing to export; you already own the files.
