✅ What is sequencer?

Sequencer allows you to create simple and clear sequence diagrams, based on a simple grammar. Your diagram is drawn in real-time as you type, and is designed to be:

• easy to edit
• easy to share
• easy to version control

Sequencer is free and open-source, distributed as a single .exe (no installer), and has just the features you need to share and document your idea quickly.

🎥 Demo

⚡ Simple to get started

💬 Describe your sequence

Client -> Server: Request
Server -> Server: Parses request
Server -> Service: Query
Service -> Server: Data
Server -> Client: Response

💥 Your diagram is ready to go

• paste right in to chat, email, your wiki page
• export as a .png file
• share the source, or better yet - version control it!

See the Grammar page on the wiki for details of the current grammar.
