Mind-expander vs Provena

Mind-expander and Provena are both agent frameworks 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.

Mind-expander

The agent drives the canvas: it can run `npx mind-expander` in the background, load skill integrations, and build guided tours through architecture. You see the same graph the agent is reasoning about, which means review decisions and refactor plans are grounded in actual dependency structure — not the agent's approximation of it. That shared view is the differentiator. The ceiling arrives with language support: Rust and TypeScript are covered, the docs describe more language frontends as planned. Teams whose core services are in Go, Python, or Java will hit that wall on day one.

Provena

Provena wraps around retrieval steps, tools, and context assembly logic to log where every chunk of data came from, hash it for tamper detection, and surface that audit trail when something breaks or an auditor asks. The vendor describes six framework adapters, an MCP server, PostgreSQL storage, and a policy engine — covering most standard Python-based pipelines without requiring a hosted service. Installation is self-hosted and free. The ceiling appears when your compliance requirement goes beyond audit trails: Provena is a passive tracking library, not an enforcement layer, so it records what happened but does not block a bad retrieval from reaching the model. Teams with hard EU AI Act enforcement obligations pair it with a separate policy gate.

Attribute	Mind-expander	Provena
Pricing	Free	Free
Free trial	No	No
Open source	Yes	Yes
Has API	No	Yes
Self-hosted option	Yes	Yes
Platforms	Web (browser-based), CLI (npx)	Python
Pros	Source-backed dependency graph generated from actual code rather than agent inference, so the agent's architecture reasoning is grounded in real module relationships instead of reconstructed approximations that break on unfamiliar patterns. Agent-steerable canvas with guided tour support, which means an AI agent can walk a developer through an unfamiliar codebase interactively — replacing a static wiki page that goes stale the week after it's written. PR and commit impact visualization scoped to the actual nodes changed, so reviewers see cross-boundary effects in the dependency graph without manually tracing every import chain. Fully open-source under Apache-2.0 with no paid tier, so the tool can be self-hosted and extended without a licensing negotiation when your team needs a custom language frontend or a different rendering surface. First-class Claude agent integration via a dedicated skill directory and hooks, which means agent setup follows a documented protocol rather than a trial-and-error prompt engineering session.	Cryptographic hashing of context chunks at retrieval time, so you can prove after a bad decision whether the data was modified between ingestion and inference — without this, you are reconstructing events from logs that were never designed for forensics. Six framework adapters described in the docs, which means most Python-based RAG or agent stacks get instrumentation without a custom integration layer. PostgreSQL-backed audit storage, so the provenance trail is queryable and retainable for the duration a compliance regime requires — not just written to a flat log that gets rotated. Policy engine that can flag staleness and provenance violations against configurable rules, which means a single misconfigured retriever shows up as an anomaly rather than silently degrading answer quality for weeks. Fully self-hosted and open-source, so the audit data never leaves your infrastructure — a hard requirement for teams in regulated industries where sending context logs to a third-party SaaS is not an option.
Cons	Language support is limited to Rust and TypeScript at the time of publication — teams with Go, Python, Java, or mixed-language services cannot use the graph features at all. There is no workaround short of contributing a new language frontend. Teams in those stacks will evaluate a different static analysis or diagramming tool from day one. No API surface is exposed, so integrating mind-expander into a CI pipeline or a custom agent harness outside the supported skill integration requires forking the project and building that surface yourself — at which point you are maintaining a fork. The agent integration is documented specifically for Claude; teams running GPT-4, Gemini, or a self-hosted model will find the skill directory and hooks are Claude-shaped, and adapting them to a different agent framework is undocumented and likely manual.	Provena is a passive observer: it records what entered the context pipeline but does not block a stale or untrusted source from reaching the model. Teams whose compliance requirement is active enforcement — reject this retrieval, do not just log it — must build a blocking layer on top, effectively maintaining two systems where they expected one. With 23 open issues and 2 stars on GitHub at the time of scrape, the project is early-stage and community support is thin. When an adapter breaks against a framework update, the fix timeline depends on a single maintainer; teams with production SLAs are on their own until a patch lands. PostgreSQL is the only described storage backend. Pipelines already standardised on a different data store — a managed cloud warehouse, an observability platform — face a schema translation step or run a second database exclusively for provenance records, which most teams will not accept at scale.

Bottom line

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