An advanced symphony alternative thats also open source (autonomous engineering)

[jaeko44]

Bosun already does everything Symphony does and more while being 100% open source forever with no subscriptions and just connect your existing codex oauth or api keys (or opencode/claude/copilot)

It supports:

A full workflow builder (n8n style with mcp, tools, cli commands, conditions, loops, agent triggers)

And over 50 ready templates that transform bosun into a fully automated symphony if the templates are activated entirely

Or

Build your own workflows.

Other features:
Kanban board for task management
Voice agents with tool access
Multi workspace and repo support
Telegram for notifications
Cloudflare tunnels for remote access
Code without lifting a finger
Control your computer without lifting a finger (using just your voice in real time)
Workflows that can truly collect evidence if a task was truly done
A context shredder that continuously maintains long running agent context windows in real time by compacting the oldest messages and useless tokens from tool calls.

Would love some feedback from users that are interested in projects like Symphony.

Also FYI symphony has the same flaw that Bosun had initially. The automations were done in modules - and not workflows. This makes it rigid, harder to continuously improve because you need to modify the code to include new automations - makes it harder to customise the instance for the end user because all the automations are just enabled by default or behind complex settings.

Why workflows are better? Because they come as templates - users can open the guts of these workflows and see a familiar n8n style workflow builder that let's them :

1. Create new workflows for their specific needs
2. Edit existing templates
3. Decide Wether to disable or enable a workflow
4. Run workflows manually using a manual flow launcher to test and or trigger one time transformations on the codebase etc.
