Axomind : planning, encrypted messaging and mind maps. Self-hosted.

Sebastien VEZZANI — Sun, 24 May 2026 11:22:44 +0000

Hello. I'm a solo developer. I built Axomind.

It's a collaborative platform combining Gantt planning, encrypted messaging (AES-256-GCM) and mind maps. Zero tracking. 26 themes (light and dark variants).

The full stack runs on a single refurbished mini PC. Intel i5, 2 cores, 16GB RAM, 35W. 100€ on the second-hand market. 8€ per month in electricity.

Load tested at 200 concurrent users. Zero failures. Median response 78ms. Self-hosted cost is about 90% below an equivalent AWS setup.

The client keeps a local copy of the data and only asks the server for what changed since the last sync. An in-memory cache sits in front of the database. Deletions propagate as small markers. Sensitive text fields are AES-256-GCM encrypted before touching the disk. The database shows ciphertext, never plaintext.

294 client-side integration tests. 400+ CI/CD pipelines. Server-side load benchmarks. DevTools profiling on the client.

The application source code is private by security choice. Builds, docs and install guides are public. Beta, testable on Android, Windows and Linux.

Bot API included. MCP layer planned on top of it for supervised AI agents.

I'm here to share what I've built and connect with people who take privacy, architecture and real performance seriously.
