ClientFlo vs Twenty CRM: MIT vs AGPL, No Docker Required
A detailed comparison of ClientFlo and Twenty CRM across license, deployment, features, and total cost of ownership for small teams. Both are open-source — but they're not the same.
Two Open-Source CRMs, Two Philosophies
Twenty CRM is the most popular open-source CRM on GitHub (44K+ stars). It's backed by Y Combinator, built in TypeScript, and aims to be the open-source Salesforce. ClientFlo is younger but takes a different approach: MIT license instead of AGPL-3.0, Firebase backend instead of PostgreSQL + Docker, and an all-in-one product that includes invoicing, time tracking, and client portal out of the box.
License: MIT vs AGPL-3.0
This is the biggest difference. Twenty uses AGPL-3.0, which requires that any modified version distributed to users must also be AGPL. If you fork Twenty and add proprietary features, you must release those changes. ClientFlo uses MIT — you can fork, modify, add proprietary features, sell it, do anything. No copyleft obligations. For startups and agencies building on top of the code, MIT is significantly more permissive.
Deployment: Node.js vs Docker Compose
Twenty requires Docker Compose with PostgreSQL. You need a server with at least 2GB RAM, Docker installed, and PostgreSQL configured. ClientFlo runs on Node.js + Firebase — no Docker, no database server. Deploy on Vercel in 2 clicks or on any Node.js VPS in 10 minutes. The Firebase backend means zero database management.
Built-in Features
ClientFlo includes invoicing, time tracking, and a client portal as core modules — not plugins or extensions. Twenty focuses on project and contact management and requires plugins or custom development for invoicing and client portals. Both have Kanban project views, but ClientFlo adds built-in time tracking (start/stop timer, billable hours) and a full invoice management system with line items, tax, and payment tracking.
Cost of Ownership
Twenty self-hosted: Docker server ($15-50/month) + PostgreSQL + domain. ClientFlo self-hosted: $0 (Firebase Spark + Vercel Hobby + Cloudinary Free + Resend Free). Twenty Cloud (hosted by Twenty): starts at $9/user/month. ClientFlo has no hosted tier — it's self-hosted only, so your cost is exactly $0 for the infrastructure. The trade-off: Twenty Cloud gives you managed hosting. ClientFlo gives you zero cost.
Which Should You Choose?
Choose ClientFlo if: you want MIT licensing, need invoicing/time tracking/client portal built in, don't want to manage Docker/PostgreSQL, or want a $0 infrastructure cost. Choose Twenty if: you need a highly customizable data model (Twenty's 'Notion-like' approach), you already run Docker/PostgreSQL, or you want the larger community (44K GitHub stars). Both are great open-source projects — they just optimize for different trade-offs.
