Codowave vs Legioni

Codowave 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.

Codowave

The core loop is fully unattended — Codowave reads a ticket from Linear or Jira, plans the change, writes code, runs the test suite, self-reviews, and submits a PR. That loop fits best when the issue is well-scoped and the acceptance criteria are explicit; ambiguous tickets produce ambiguous diffs. The tool runs continuous security and quality scans, which means findings don't queue behind sprint planning. There is no self-hosted option and no API, so teams with air-gapped environments or strict data-residency requirements hit a hard wall immediately. BYOK (bring your own LLM key) is supported, giving cost-sensitive teams control over model spend.

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.

Attribute	Codowave	Legioni

Platforms	Web-based cloud platform; integrations with GitHub, GitLab, Linear, Jira, Asana, Slack	npm, Node.js
Pros	Fully autonomous issue-to-PR loop, so engineers never context-switch into routine implementation work — the PR arrives for human sign-off rather than human execution. Self-review step before the PR opens, which means AI-generated diffs are filtered once before they reach your human reviewers, reducing the review queue noise that makes raw AI coding tools exhausting to manage. Continuous security and quality scanning without sprint scheduling, so scanner findings get addressed when they are found rather than aging in a backlog until they are a compliance problem. BYOK model key support, so teams that hit API cost ceilings can swap underlying models without negotiating a vendor change — a one-configuration adjustment rather than a migration. Linear and Jira integration, which means the agent operates inside the issue tracker workflow teams already use rather than requiring a parallel task management layer.	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	Ambiguous or under-specified tickets produce ambiguous PRs — the agent has no mechanism to ask a clarifying question, so issues without explicit acceptance criteria generate diffs that require significant human rework, defeating the throughput argument entirely. No self-hosted option and no data-residency controls: teams in regulated industries or with air-gapped environments cannot use this tool at all, and the conversation ends there rather than at a workaround. Usage caps metered by issues-per-month mean a team running a large backlog clearance sprint can exhaust a tier mid-month; the scaling cost to the next tier is steep enough that teams with irregular, high-volume bursts often reach for a self-hosted open-source agent instead. No API surface means Codowave output cannot be wired into a broader internal automation pipeline programmatically — teams that want to trigger downstream workflows from a closed issue must build against the PR event in their Git host, not against Codowave directly.	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

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