Codeep vs Legioni

Codeep and Legioni are both cli coding agents 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.

Codeep

Codeep is an open-source, terminal-native autonomous agent that reads your project structure, plans a sequence of steps, edits files, runs shell commands, and checks its own output against your build and test suite before declaring done. You describe the goal; it handles the steps. The self-verification loop — where it catches a broken typecheck and fixes it without prompting — is the part that separates it from a glorified shell wrapper. The ceiling appears on projects where the agent's context window fills before it has mapped the full dependency graph; community reports suggest large monorepos with deep cross-module dependencies push that limit faster than single-service repos. At that point, teams either scope tasks more tightly or reach for a dedicated sub-agent delegation pattern.

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	Self-verification after every change set — the agent runs your build and tests and fixes failures before surfecting results — so you are not debugging a half-finished diff at the end of a long task. Provider-agnostic model routing across 9+ providers including local Ollama models, so switching away from a hosted API when costs spike is a config change rather than a platform migration. Plan Mode shows every file and command before execution, so teams with sensitive codebases or compliance requirements can review the agent's intent before a single line changes. Sub-agent delegation keeps the main context focused by offloading self-contained tasks (research, review, testing) to specialist agents that run in their own fresh windows, which means large tasks stay coherent longer than a single flat context allows. Apache 2.0 open-source with self-hosted option, so organizations running custom or private LLM infrastructure are not forced to route code through a third-party SaaS platform.	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	On large monorepos with deep cross-module dependencies, the agent's context window fills before it has mapped the full dependency graph — tasks that span many modules require manual scoping or staged sub-agent delegation, and the verification loop can cycle on failures it cannot resolve without broader context. Codeep is CLI-first; teams that rely on an IDE canvas to visualize agent state, inspect intermediate steps, or approve changes inline will find the terminal output model insufficient — those teams typically switch to an IDE-native agent like Cursor or a visual workflow tool. With roughly 4,500 downloads in the past 30 days and 19 GitHub stars at time of data capture, the community is early-stage — production war stories, third-party integrations, and community-maintained skill libraries are sparse compared to established agent frameworks, which means debugging edge cases lands entirely on your own investigation or the vendor's docs.	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

Only Codeep exposes a public API. Choose based on which difference matters most for your workflow.
