Guidon vs HacknPlan: for game developers working with AI agents
HacknPlan pairs tasks with a game design model. Guidon adds dead ends, verified knowledge, AI agents and engine plugins.
Checked 2026-11-09. Features change - see HacknPlan's site for theirs. All comparisons
The short answer
HacknPlan links tasks to a living game design document. Guidon is for developers who build with AI agents: an official MCP server, dead ends with each task, and engine plugins that bring them into the editor.
Choose Guidon if
- You want AI agents with an official MCP server
- You want dead ends linked to scenes in Godot
- You want to self-host
Choose HacknPlan if
- You plan around a game design model (GDD)
- Your team already uses it for production
At a glance
Guidon is better on 6 of 7 topics below; HacknPlan is better where it says so.
| Topic | Guidon | HacknPlan |
|---|---|---|
| Self-hosting | Docker Compose with plain PostgreSQL; every feature, no plan limits on your own install. | Cloud only. |
| Source code | Open source (AGPL-3.0). | Closed source. |
| What was already tried | Better: attempts are part of every task - approach, outcome and why it failed. An agent starting the task gets the dead ends with start_task, and is reminded to record its own. | Not a built-in feature in their docs (as of 2026-11-09); attempts end up in comments, if anywhere. |
| Verified vs AI-guessed knowledge | Better: project memory keeps what a person verified apart from what an AI wrote; anything an agent adds or changes waits in a review queue. | No separate verified-vs-AI status in their docs (as of 2026-11-09). |
| Context in your repository | Better: export the project as AGENTS.md - approved brief, verified facts, known dead ends - for Claude Code, Codex and Cursor. | No AGENTS.md export in their docs (as of 2026-11-09). |
| AI agents (MCP) | MCP server and REST API; works with Claude, ChatGPT, Cursor, Codex and any MCP client. You bring the AI - no AI credits. | No official MCP server listed (as of 2026-11-09); community servers wrap its API. |
| Game design document | Decisions and knowledge per project. | Better: a game design model linked to tasks. |

Questions
Can I keep my game design document?
Keep it where it is and link it as a knowledge source; Guidon's decisions and verified facts sit next to the tasks.
