Code Review Graph vs PortalJS

Code Review Graph and PortalJS 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.

Code Review Graph

The tool builds a dependency graph of your codebase locally, then exposes that graph through MCP so Claude Code, Cursor, or any compatible assistant can ask targeted questions: which files are affected by this change, what is the impact radius, which communities cluster around this module. For large monorepos, this is the difference between a useful review context and a truncated one. The analysis runs entirely on your machine — no source code leaves the environment. The gap shows up when you need deep semantic understanding beyond structural imports; graph topology tells you what calls what, not whether the logic is correct.

PortalJS

PortalJS is an open-source, AI-native framework where you describe the portal you want — audience, datasets, layout — and a set of documented skills scaffold a real Next.js project: pages, tables, charts, and maps wired to your data. The output is plain, editable code, not a locked runtime, so your team owns every file from day one. It decouples from whatever catalog or metadata backend you already run — CKAN, DKAN, DataHub, OpenMetadata — without forcing a rewrite. Large files stream via Cloudflare R2, and in-browser SQL queries run against Parquet via DuckDB-Wasm with no backend server required. The wall appears when your portal requires conditional data logic or workflow complexity beyond what a composable skill covers; that is when teams layer in custom Next.js code themselves.

Pros	Reads only changed files and their structural dependencies rather than entire repositories, so your AI assistant's context window goes toward relevant code instead of noise from unrelated modules. Impact radius scoring on change analysis, so reviewers see which downstream files carry the highest risk before opening a single one — rather than manually tracing imports across a large graph. Fully local execution with no cloud dependency, so source code never leaves the environment — a hard requirement for teams under data residency or confidentiality constraints. MIT-licensed with no paid tier and pip installation, so there is no procurement gate, no usage cap, and no feature that unlocks only when you upgrade. Unified graph model across multiple languages, so a polyglot monorepo gets consistent structural queries without separate tooling per language stack.	MIT open-source license with no runtime lock-in, which means you fork, audit, and self-host without negotiating a vendor contract or discovering a proprietary dependency mid-project. Decoupled from your data catalog backend — CKAN, DKAN, DataHub, OpenMetadata, and custom APIs are all valid targets — so migrating your metadata system does not require rewriting your frontend. In-browser DuckDB-Wasm queries over Parquet files, so you can offer SQL-level exploration of multi-gigabyte datasets without provisioning or paying for a query server. AI skills scaffold the full Next.js project from a plain-language brief, which means a developer can have a real, editable portal codebase — pages, charts, maps — without writing repetitive boilerplate across every engagement. Custom skills are documented, version-controlled, and picked up automatically by the assistant, so a capability you author once is reusable across every portal your team ships.
Cons	The graph captures import and call structure, not runtime behavior or semantic intent — questions like 'does this change break business logic in the billing module' return no useful answer, and teams with that requirement add a dedicated semantic search tool, maintaining two systems in parallel. MCP is the only consumption interface; development environments without MCP support get nothing from this tool. Teams using IDE plugins or assistants that do not expose MCP cannot integrate it without building a custom bridge. Community detection and architecture overview queries return structural clusters, which require a developer to interpret the output against domain knowledge — for teams onboarding to an unfamiliar codebase, the graph answers 'what talks to what' but not 'why.' Teams that need the 'why' typically switch to tools that ingest documentation and comments alongside the dependency graph.	The skills model covers a defined set of views — tables, line/bar/area/pie/scatter charts, GeoJSON maps. Portal requirements that fall outside that set — custom dataset comparison tools, conditional filtering logic, domain-specific visualizations — drop you into raw Next.js development, which PortalJS does not accelerate; teams with those requirements frequently find a general React component library and a direct backend connection is a shorter path. No API surface for programmatic platform control means teams that need to automate portal provisioning across dozens of datasets or departments cannot script against PortalJS itself; they script around it using the CLI or manage scaffolded repos directly, adding operational overhead at scale. The framework assumes a static or backend-connected deployment model. Organizations that require real-time data freshness with server-side rendering logic beyond a static export face an architecture gap — teams in that situation typically end up maintaining a custom Next.js server layer alongside PortalJS output, running two things where they expected one.

Bottom line

Code Review Graph is free while PortalJS is paid; only Code Review Graph exposes a public API. Choose based on which difference matters most for your workflow.
