CodeBoarding
CodeBoarding maps your codebase as an architecture diagram so you can review what a pull request rewires, not just its diff.
The pitch — review the change, not the diff — addresses a real problem, and CodeBoarding answers it with something you can actually look at: a Mermaid architecture comment on the pull request showing which components changed and which dependencies are new. Static architecture diagrams will not catch runtime bugs or security issues, so do not buy it for that. But if your team merges agent-authored pull requests and nobody can hold the whole system in their head, $9.99/month for a system-level view is one of the cheapest sanity checks in the stack. Against heavier tools like CodeScene or AppMap, it is narrower in scope but far cheaper to trial — the Free tier covers every repository you

Skip CodeBoarding if you need security scanning, runtime tracing or performance profiling, or if your code cannot be sent to any external model provider even with your own key.
Free analyses are metered per account, and the page does not publish the meter's ceiling, so you discover the limit by hitting it mid-review.
Free is unusually generous for this category — every repository you choose, public or private, no card. Pro at $9.99/month is aimed at engineers reviewing every day. That sits well below heavier peers like CodeScene or AppMap, which is the trade: narrower scope, far cheaper to trial. Enterprise is custom and invoiced.

About CodeBoarding
CodeBoarding is an open-core architecture diagramming tool for teams shipping code written by AI coding agents. Instead of reading a 112-file diff and guessing which changes matter, you get an interactive map of your system — components, dependencies, and what a pull request actually changes. The MIT-licensed engine runs locally, and setup takes about one pull request: you sign in, pick repositories, then merge a pull request that adds two GitHub Actions workflow files and nothing else. From there, every pull request gets a change diagram. The GitHub Action posts a Mermaid architecture comment showing changed components and new dependencies, so you can see that Payments now depends on Identity without leaving GitHub. The same diagram opens in the browser as a clickable system view, in VS Code, Cursor and Windsurf via the VS Code Marketplace and Open VSX extension, or in CI. Analysis is static, covering Python, TypeScript, JavaScript, Java, Go, PHP and C#. You can export diagrams to PNG, track git changes, compare branches, trace dependencies, and optionally point LLM providers (OpenAI, Anthropic, Google, Vercel, OpenRouter, Ollama) at the map for documentation. The dashboard sorts open pull requests by what they are waiting for: needs you, ready to merge, blocked, waiting on others. Pricing is straightforward: Free covers every repository you choose with metered analyses and three levels of diagram depth; Pro at $9.99/month removes the meter, goes ten levels deep, speeds generation, and adds health monitoring and iterative changes; Enterprise is custom.
Behind the Verdict
CodeBoarding targets a specific moment: the pull request that touches 112 files with green tests and 140 bot comments, where the diff tells you nothing about whether Payments now depends on Identity. It draws the system from the code itself, then overlays the change. You get six components, the changed ones colored, new dependencies marked, and a click to see what flows in and out. That framing is the product's real value — a system-level decision shown as a system-level decision. Strengths: setup is one merged pull request that adds two GitHub Actions workflow files; the engine is MIT licensed and runs locally; analysis is static and covers Python, TypeScript, JavaScript, Java, Go, PHP and C#. The dashboard sorts open pull requests into needs you, ready to merge, blocked, and waiting on others, which is a genuinely useful queue when agents produce faster than humans review. You can export to PNG, compare branches, trace dependencies, and optionally let an LLM provider — OpenAI, Anthropic, Google, Vercel, OpenRouter or Ollama — write documentation from the map. Bringing your own key means the runner calls your provider directly. Weaknesses: it is an architecture visualization and blast radius tool, not a linter, security scanner, or profiler. The CLI install (pipx install codeboarding --python python3.12 with an extra index URL) is a real barrier for developers not working in Python, and it is required before anything shows in your editor. Its value concentrates in teams using AI coding agents; if you write code by hand at a comfortable pace, the blast radius framing is less urgent. It is open-core, so health monitoring and iterative changes sit behind the Pro tier. Where it fits: teams running Cursor, Windsurf, Claude Code or Codex who need to keep ownership of what merges. Where it does not: security scanning, runtime tracing, perf profiling, or environments where source excerpts cannot reach any external model provider.

Real-world workflow fit
Concrete scenarios for the personas CodeBoarding actually fits — and what changes day-one when you adopt it.
Sign in, pick repositories read-only, merge the setup pull request that adds two GitHub Actions workflow files. The Action draws a baseline, then a change diagram on every pull request.
Outcome: Each PR carries a Mermaid architecture comment showing changed components and new dependencies, so you decide whether Payments depending on Identity is acceptable before merging.
Open the pull request as an interactive diagram in the browser, read changes grouped by component, then copy that context into the agent's next prompt.
Outcome: You review at the level where decisions live and hand line-by-line work back to the agent with system context attached.
Open a finished diagram for the repository in the browser or in the VS Code, Cursor or Windsurf extension, clicking components to see what flows in and out.
Outcome: You get the shape of the system in one session instead of reading a stale wiki page, and can compare branches to see how it shifted.
Use Cases
- Visualize a codebase's architecture before starting a new feature so you can scope the task against the real system
- Review the blast radius of AI-generated changes in a pull request before merging
- Onboard new team members with an interactive system map instead of a stale wiki page
- Trace a regression back to its root cause through dependency graphs
- Keep architecture diagrams automatically updated via a GitHub Action in CI
- Generate documentation of components and subcomponents using an LLM provider of your choice
- Compare branches to see how architecture shifted across a release
- Sort open pull requests by what they are waiting for: needs you, ready to merge, blocked, waiting on others
Limitations
- CodeBoarding is an architecture visualization and blast radius tool, not a linter, security scanner, or profiler.
- It requires installation via pipx with an extra index URL (pipx install codeboarding --python python3.12 --pip-args="--extra-index-url https://pip.codeboarding.org/simple/"), which is a real barrier for developers not working in Python.
- It requires installation at the CLI level before anything shows up in your editor or webview, unlike simpler extensions that activate on install.
- Static analysis support is limited to Python, TypeScript, JavaScript, Java, Go, PHP and C#.
- Its value is concentrated in teams that use AI coding agents; if your team writes code by hand, the blast radius framing is less useful.
- It is open-core, so the premium features — health monitoring and iterative changes — sit behind the Pro tier.

Free
$0
Ideal for
Individuals and small teams trialling architecture review, or anyone who wants a live diagram of a public codebase with no account.
What this tier adds
Free entry point: every repository you choose, metered analyses each month, diagrams three levels deep, browser, editor and CI access, PNG export, no card.
Pro
$9.99/mo
Ideal for
Engineers reviewing every day on a codebase large enough that a three-level diagram stops being useful.
What this tier adds
Removes the meter, goes ten levels deep instead of three, speeds generation, and adds health monitoring and iterative changes.
Enterprise
Custom
Ideal for
Organisations rolling CodeBoarding out across teams with custom environments and integrations.
What this tier adds
Adds custom environments and integrations, priority support, custom requests and features, and early access to new features; invoiced rather than a self-serve subscription.
Where the pricing makes sense
The company stage and team size where CodeBoarding's pricing actually pencils out — and where peers do it cheaper.
Free is unusually generous for this category — every repository you choose, public or private, no card. Pro at $9.99/month is aimed at engineers reviewing every day. That sits well below heavier peers like CodeScene or AppMap, which is the trade: narrower scope, far cheaper to trial. Enterprise is custom and invoiced.
Setup time & first value
How long it actually takes to get something useful out of CodeBoarding — broken out by persona, not the marketing-page minute.
About five minutes including the coffee: sign in, pick repositories one at a time or as a whole organisation (read-only, changeable later), and merge the one prepared pull request that adds two workflow files. The CLI install with pipx and the extra index URL adds a step before anything appears in your editor, and that step is heavier if you are not working in Python.
Switching to or from CodeBoarding
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From hand-drawn architecture diagrams: merge the setup pull request and let the engine draw the baseline from the code itself, so the diagram stops going stale.
- →From AppMap: point CodeBoarding at the same repositories for static architecture and per-PR blast radius; note it will not replace AppMap's runtime tracing.
- →From CodeScene: run CodeBoarding alongside it if you still need code health and security analysis, using it for the PR-level system view.
- ↗To CodeScene: export diagrams to PNG for reference, then move to CodeScene if you need deep code health, security and quality analysis rather than architecture visualization.
- ↗To AppMap: keep the exported diagrams as documentation and move to AppMap if you need runtime tracing and performance profiling.
- ↗To a wiki or diagram tool: export diagrams to PNG or copy the Mermaid change diagram from the pull request comment, accepting that they no longer update themselves.

Featured Head-to-Head Comparisons
Codeboarding vs Spider Cloud
Spider Cloud and CodeBoarding serve completely different needs. If you need to feed real-time web data into AI agents or RAG pipelines, Spider Cloud is the clear choice with its pay-as-you-go pricing and browser AI commands. If you're a team using AI coding agents and need to visualize codebase architecture before merging, CodeBoarding fills that gap. They are not direct competitors; choose based on whether your primary need is data ingestion or codebase understanding.
Codeboarding vs Temporal Ai
Temporal AI and CodeBoarding solve opposite problems: Temporal ensures your AI agents and workflows survive crashes and retries; CodeBoarding keeps your codebase architecture visible when AI agents write code. If you're building production agents that must not lose state, pick Temporal. If you're trying to understand and review AI-generated code, pick CodeBoarding. They can even complement each other—Temporal for execution reliability, CodeBoarding for architecture clarity.
Codeboarding vs Voyage Ai
For enterprise RAG needing high-accuracy retrieval on domain-specific data, Voyage AI is the specialized choice with its advanced embeddings and rerankers—but you'll need to talk to sales. For teams using AI coding agents that need architectural visibility and guardrails, CodeBoarding offers a practical freemium solution with easy setup. Pick the one that matches your primary workflow: search accuracy vs. codebase understanding.
