Open-Kritt vs Vmette

Open-Kritt and Vmette 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.

Open-Kritt

The tool runs parallel AI agents across a codebase, so vulnerability discovery that would serialize into hours on a single-context scan distributes across concurrent analysis threads. It targets security researchers and bug bounty teams who need to sweep repositories at scale, not review a function at a time. Self-hosting is supported under AGPL-3.0, which means your code and findings never leave your infrastructure — a requirement for any org with compliance constraints. The open-source core is inspectable and forkable, but managed scans are a paid-only feature, so teams that want the hosted workflow face a significant spend threshold. The page describes GitHub integration as a first-class path, making it a practical fit for teams already running security workflows inside existing CI infrastructure.

Vmette

The threat model vmette solves is concrete: prompt injection on a fetched web page, a malicious package in an AI-suggested install, or model output that does something you didn't intend — all of it lands inside the VM, not on your host. The isolation is hardware-level, not a container namespace that a determined process can escape. Because everything runs on-device, no agent output leaves your machine to a third-party cloud sandbox. The ceiling appears at the edges: vmette is macOS-only, and teams whose agents need to run on Linux servers or in CI pipelines will need a different isolation strategy.

Pros	Parallel agent analysis across large codebases, so security researchers are not bottlenecked by single-context limits that cause coverage gaps on repositories too large for one model pass. AGPL-3.0 open-source license with self-hosting support, which means organizations with compliance requirements can audit the tool's behavior and keep all code and findings on their own infrastructure rather than routing through a third-party service. Direct GitHub repository integration, so teams can point the tool at existing repos without building a separate code ingestion or preprocessing step. Support for Codex and Claude Code model backends, so teams can align the analysis engine with the model their organization already has access to or trusts for security-sensitive tasks. Inspectable agent orchestration code under an open license, which means a security team can verify exactly what the agents are executing — a requirement that opaque SaaS tools cannot satisfy.	Hardware-isolated VM boundary rather than a container namespace, so a misbehaving agent or malicious package cannot reach your host filesystem or credentials through a kernel-sharing escape path. ~1-second boot time on macOS, which means the isolation overhead does not force you to batch or pre-warm — each agent invocation gets a fresh, ephemeral environment without a meaningful delay penalty. Fully on-device with no cloud dependency, so agent output, file contents, and API tokens passed into the VM never transit a third-party sandbox service. MIT-licensed and free with no commercial tier, so teams that would otherwise pay for a hosted sandbox can run unlimited isolated executions without metering or subscription cost. MCP integration is documented, which means Claude Code, Cursor, and other MCP-compatible agents can delegate execution directly without a custom integration layer.
Cons	Managed scans are a paid-only feature with a spend threshold the validator context confirms is substantial; independent researchers and small bug bounty teams operating on limited budgets hit this wall immediately and are forced to self-host, which shifts the burden of infrastructure provisioning, scaling, and maintenance entirely onto the team. Self-hosting the agent infrastructure requires operational capacity that security research teams — typically focused on findings, not DevOps — often lack; teams without a dedicated infrastructure engineer end up spending sprint time on setup and uptime instead of auditing, and those teams frequently abandon self-hosted options for managed security tooling that absorbs that operational cost. No API is available per the tool's current documentation, which means teams that want to embed Kritt.ai's analysis into an existing CI/CD pipeline or trigger scans programmatically from another system face a hard integration ceiling; teams requiring API-driven automation switch to tools with exposed endpoints.	macOS-only: teams whose agents run in Linux-based CI pipelines, on Linux developer workstations, or in any cloud environment hit a hard stop — the virtualization layer is Apple-specific, and there is no Linux port described in the repository. Those teams route to a different isolation solution entirely. No API surface: external systems cannot programmatically query vmette's state, inspect VM lifecycle, or integrate isolation into orchestration tooling beyond what the MCP interface exposes. Teams building automated pipelines with custom tooling will find the integration surface thin. Early-stage project with a single-digit star count and no open issues, which means community-sourced debugging help, third-party tutorials, and documented production war stories are absent — teams encountering edge cases in agent behavior are working from the README and source alone.

Bottom line

Open-Kritt is paid while Vmette is free. Choose based on which difference matters most for your workflow.
