ITDoc Generator vs Legioni

ITDoc Generator and Legioni are both coding assistants tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

ITDoc Generator

ITDoc Generator takes structured input from IT practitioners and produces formatted documentation — onboarding guides, network infrastructure write-ups, incident response runbooks, and standard operating procedures — without requiring the writer to start from scratch. The workflow is one-shot: you provide the details, the tool generates the document. There is no agent loop, no multi-step reasoning, no back-and-forth task planning. For a solo sysadmin or a small MSP that needs to hand a client a clean procedure document by Friday, that is enough. Teams with complex, organization-specific formatting requirements or tightly branded templates will hit the ceiling quickly.

Legioni

The orchestrator receives a plain-language task in opencode, breaks it down, and hands it to a chain of specialist agents — architect, implementer, reviewer, test-strategist — in sequence. Each step feeds the next; the loop closes only when tests pass. The 'lesson promotion' mechanism lets teams encode what they learn into persistent agent behavior, so the same mistake doesn't resurface two projects later. The hard boundary: Legioni runs inside opencode, full stop. If your team is not already on opencode or cannot adopt it, the architecture is irrelevant — there is no standalone path and no API to route through a different runtime.

Pros	One-shot document generation from structured input, so a sysadmin who would otherwise spend two hours wrestling with a blank template gets a reviewable first draft in minutes instead. Coverage across five IT documentation types — onboarding, network infrastructure, runbooks, SOPs, and MSP deliverables — which means a single tool handles most of what a small IT team produces rather than requiring separate templates for each document type. Three free documents available without commitment, so you can verify output quality against your actual use case before the tool costs anything — no wasted sprint discovering the output format doesn't fit your standards. Designed for practitioners without dedicated technical writing resources, which means a system administrator or MSP technician can produce client-ready documentation without routing every draft through a specialist.	Test-driven agent loop closes only when tests pass, so you are not manually checking whether the implementer's output actually works before shipping it to review. Specialist agents handle discrete roles — architecture, implementation, review, test strategy — which means a single task does not collapse into one undifferentiated prompt that loses track of constraints halfway through. Lesson promotion persists learned behaviors across sessions and projects, so teams stop re-encoding the same project rules every time they open a new task. Zero-install path via npx means you can run `legioni init` in a new repo without touching your global Node environment, keeping adoption friction low for the first experiment. MIT license and self-hosted operation mean the agents run entirely within your environment — no usage data leaves to a vendor API beyond whatever opencode itself sends.
Cons	No API access and no self-hosted option means every document you generate passes through the vendor's environment — for runbooks or network diagrams containing real infrastructure details, that is a hard blocker for any organization with data-residency or security requirements, and those teams will move to an internal tool or a self-hosted alternative instead. Output is generated once and handed back to you; there is no iterative refinement loop, no memory of previous documents, and no way to enforce organization-specific formatting or brand templates at the generation stage — teams with strict client deliverable standards end up doing enough post-generation editing that the time savings erode, at which point the value proposition against a well-maintained Word template library becomes difficult to defend. No integrations with knowledge management platforms means generated documents live wherever you save them — teams that need documentation to land in Confluence, Notion, or a ticketing system must handle that transfer manually every time, and once volume grows past a handful of documents per week, that friction pushes teams toward tools that write directly to their knowledge base.	Legioni is a hard dependency on opencode: every agent, every loop, every lesson runs inside opencode's runtime. Teams on Cursor, Cline, or any other AI coding environment cannot use this tool — the only path forward is adopting opencode first, which is a separate adoption decision with its own trade-offs. The project's public repository shows five commits and a small star count, which means edge cases in the agent loop, lesson promotion conflicts, and stack detection failures are under-documented and under-reported. Teams hitting unexpected behavior have no community issue history to search and no support channel beyond filing a GitHub issue themselves. Lesson promotion is a manual, explicit action — the agents do not automatically surface or apply learned behaviors without team intervention. Projects where nobody curates the promoted lessons see no compounding benefit across sessions, which makes the core differentiating feature opt-in rather than default.

Bottom line

ITDoc Generator is paid while Legioni is free; Legioni is open source. Choose based on which difference matters most for your workflow.
