Repository-wide drift scan
Runs a local scan over a repository and ranks drift by how much it hurts, so the first thing you see is the most consequential mismatch rather than an undifferentiated list of warnings.
VibeDrift
VibeDrift is a developer tool that scans codebases for AI-generated drift and can also act as an MCP server so agents can check conventions before they write. It helps teams keep repository patterns, naming, and logic consistent as projects grow.
What VibeDrift does
VibeDrift is a developer tool for spotting and preventing AI-generated code drift as a project grows. It scans a codebase for inconsistencies, patterns that have diverged, missing guards, duplicated logic, and other signs that an agent has stopped following the repo's established conventions.
The product is designed for a workflow where AI coding agents such as Claude Code or Cursor are already writing code. VibeDrift can run as a local scanner from the CLI, and it can also run as an MCP server so the agent can query the codebase mid-task and receive evidence-backed answers before it writes or commits changes.
Core capabilities
Drift detection across files
Highlights architectural contradictions such as different patterns for similar code, missing auth checks, duplicated logic, and inconsistent naming across files.
Prioritized findings with fix guidance
Produces a Vibe Drift Score, a coherence report, scan-over-scan delta, and copy-ready fixes so the output is actionable rather than just diagnostic.
In-editor prevention via MCP
Provides an MCP server with tools such as `get_dominant_pattern`, `find_similar_function`, `check_file_drift`, `get_intent_hints`, and `validate_change` so an agent can check conventions before writing code.
Watch mode and git workflow checks
Offers a local watch mode that refreshes the memory on every save and a pre-push gate for catch-at-the-edge checks.
Deep scan for semantic consistency
Supports deeper semantic analysis for duplicate logic, intent mismatch, and AI-validated findings, with deep checks available as a paid budgeted capability.
Where VibeDrift fits
Audit a growing codebase for drift
Use the local scan on a repository when AI-generated files are starting to diverge in auth handling, error handling, naming, or data-access style. The scan ranks the most serious mismatches first so a developer can review the biggest problems without combing through the whole tree.
Prevent drift while the agent is coding
Use the MCP tools inside Claude Code, Cursor, or another MCP client when an agent is about to write new code. The agent can ask what the dominant pattern is, whether similar logic already exists, or whether a planned change would introduce drift.
Keep conventions stable during day-to-day development
Use the watch mode and pre-push checks in an active repository where files change frequently. The memory refreshes on save, and the gate helps catch regressions before they leave the local branch.
Check deeper consistency in larger repositories
Use the deep scan when you need semantic checks for intent mismatch or hidden duplicates that are not obvious from structure alone. This is the more detailed path for larger codebases or places where simple pattern matching is not enough.
Pros and Cons
Pros
- Local scans and MCP tools run on your machine and are described as free, with no login required for local use.
- It focuses on codebase-level consistency, not just single-file linting, which makes it suited to architectural drift and repeated pattern mismatches.
- The tool can be used both after the fact and before code is written, shifting from detection to prevention when the MCP server is in the loop.
- Output is prioritized and actionable: the product surfaces the worst issues first and provides fix prompts or copy-ready fixes.
- The product offers a free local starting point, with an explicit path to deeper semantic checks, watch mode, and team features on higher tiers.
Cons
- The source shows partial documentation in the captured pages, so some setup, language support, and team-workflow details are not fully visible here.
- Deep scans are limited by budget on paid plans, so the more semantic checks are not unlimited in the same way as local scans.
FAQ
How do I get started?
You run VibeDrift from the command line with `npx @vibedrift/cli .` in a project. The homepage says there is no account or configuration required to start local scans.
How is this different from ESLint or Prettier?
According to the FAQ, VibeDrift is meant to compare files and codebases rather than just validate syntax in a single file. That makes it different from tools like ESLint or Prettier, which work file by file.
Does my code get sent anywhere?
The product describes a free local scan and MCP tools that run on your machine. For deeper semantic checks, the blog says only the single function under review leaves the machine when deep mode is explicitly used.
What's the difference between Free, Pro, and Enterprise?
The site presents a free plan with local scans and limited deep scans, a Pro plan with more deep scans and in-editor checks, and an Enterprise plan for BYOC, team seats, SSO/SAML, custom rules, GitHub App automation, and dedicated support.
Does it work on old or legacy codebases?
The FAQ page includes a dedicated question about whether VibeDrift works on old or legacy codebases, but the rendered text provided here does not include the answer. The public site therefore signals that legacy-code support is addressed, but not enough detail is visible in the captured text to restate it confidently.

CreateOS Sandbox
CreateOS Sandbox is an isolated compute environment for running code and agent workloads inside Firecracker micro-VMs. It is designed for workflows that need machine-level isolation, private networking between sandboxes, and programmatic control through SDK, CLI, or MCP.
hob
hob is an independent workspace for coding agents that keeps agent sessions, terminals, history, and follow-up work organized around the tools and providers you already use. It is aimed at developers who want local control over routing, history, and workspace structure rather than a bundled model stack.
SonOf
SonOf connects to your repo and PM tool, audits the codebase and surrounding product context, and turns approved work into shipped tickets with senior engineering review. It is aimed at founders and engineering leaders who need backlog help without hiring a full team immediately.
