mindwalk vs Overplane

mindwalk and Overplane 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.

mindwalk

The tool replays Claude Code or Codex session logs against a spatial model of your repository, showing file touch history, exploration paths, and where the agent's footprint diverged from the intended task boundary. Everything runs locally as a compiled Go binary — no server, no API key, no data leaving the machine. That local constraint is also the ceiling: Mindwalk reads and visualizes; it does not flag anomalies automatically or integrate into a CI gate. Teams using it for post-session audits get a fast, honest picture of agent behavior. Teams that need automated alerts or diff-level review stay in their existing toolchain.

Overplane

Overplane is a free, open-source CLI binary that wraps Claude Code, Codex, or OpenCode in container isolation, spec-driven builds, and Z3 formal verification before a single line of code is written. Every agent run executes in a locked-down container with a restricted view of the host system, so a bad outcome means deleting a sandbox, not restoring a backup. Builds are content-hashed and content-addressable, which means you can replay any build down to a single spec and see the normalized dollar cost attached to that run. The ceiling appears early in teams who need the tool to also do its own code generation — Overplane is a build wrapper around agents you already own, not a coding agent itself.

Pros	Spatial replay of agent session paths, so you can see exploration-before-action at a glance instead of reconstructing it by reading hundreds of JSONL lines in sequence. Fully local Go binary with no external dependencies at runtime, which means session logs containing proprietary code never leave the machine — a requirement on most enterprise codebases. MIT license with build-from-source instructions, so teams can audit the binary, fork it, or embed it in internal tooling without negotiating a license. Visual file-touch history makes scope drift concrete — when an agent read files three directories outside the intended boundary, that shows up as light crossing the map rather than as a number buried in metadata. Targets the specific log formats produced by Claude Code and Codex, so there is no generic adapter layer to configure for the two most common coding-agent environments.	Every agent run executes in a locked-down container with a restricted view of the host system, so a compromised or misbehaving agent destroys a sandbox rather than your local environment or production credentials. Z3 runs on per-spec and merged Intermediate Representation models before any code is generated, which means logical contradictions in your spec surface as a pre-build error rather than a 4,000-line diff you have to reverse-engineer. Content-hashed images and content-addressable outputs make builds cacheable and replayable down to a single spec, so audit requests or incident investigations do not require reconstructing what the agent did from memory. Agent-agnostic design with per-project or per-run agent selection and normalized cost tracking across runs, which means you can benchmark Claude Code against Codex on the same spec without re-architecting anything. Apache-2.0 licensed with no hosted offering and no subscription, which means the tool introduces no vendor lock-in and no data leaving your infrastructure beyond what the agent API calls require.
Cons	Visualization is purely retrospective: there is no API, no event stream, and no CI hook, so the tool cannot block a bad session from shipping — a team that needs automated scope enforcement has to build that check elsewhere and Mindwalk contributes nothing to it. Log format support is tied to what the schema directory describes; agents that produce non-standard or extended JSONL structures require a preprocessing step before Mindwalk can ingest them, and the docs do not describe a plugin or adapter interface for this. There is no anomaly detection or scoring — the visualization shows you what happened, but deciding whether the footprint was acceptable is entirely on the reviewer. Teams that audit dozens of sessions per day and need triage prioritization will hit this ceiling quickly and move to a purpose-built audit platform that can surface outliers automatically.	Overplane does not include a coding agent — it drives Claude Code, Codex, or OpenCode, which means a team that does not already have those agents installed and API keys configured faces a multi-tool setup before a single build runs. Teams without an existing agent subscription hit this wall immediately and often reach for an integrated hosted tool instead. The tool is described as v0.0.8, which the vendor page does not present as production-stable. Teams evaluating it for a compliance-sensitive production pipeline face the specific problem of building internal policy around a binary that carries no stated stability guarantee — they document the version, pin it, and own the upgrade path. Formal spec verification with Z3 adds value only when specs are written to the schema Overplane expects. Teams migrating existing informal or prose-heavy spec documents spend the migration time rewriting specs before they see any verification benefit — the workflow does not adapt to how specs were written before.
