Understand any codebase in minutes, not days. AI-powered code intelligence that gives you the full picture before you touch a single line.
Free and open source. Business and Enterprise plans available.
Ask questions about architecture, patterns, and dependencies and get accurate answers in seconds. No more grep-and-pray.
Automated first-pass review catches security issues, style violations, and breaking changes before human review even starts.
Know the dependencies, the side effects, and the blast radius before you push. Fewer production incidents. Fewer rollbacks.
Stop waiting on teammates who "know how this works." Get answers from the source code itself, any time, on any part of the system.
Every tool you have works at the file level. But the bugs you ship, the regressions you cause, and the time you waste all come from not understanding how the pieces fit together.
New repo. No documentation. The README hasn't been updated in two years. You clone it, open the project, and stare at 400 files. You spend the first week just figuring out where things live and who to ask. Your first real PR takes 10 days instead of 2.
You change a function signature. Tests pass. Linter is green. You push. Three hours later, a service you've never heard of breaks in production because it depends on the exact return format you just modified. Nobody told you. Nothing in the code warned you.
You're deep in a debugging session. You need to understand how the auth middleware works. You find the file, but it calls three other modules. Those modules import shared utilities. An hour later, you've read 15 files and lost the thread of what you were originally fixing.
Real prompts from developers. Questions, debugging sessions, and investigations -- across unfamiliar codebases.
Ask any question about any codebase and get accurate, contextual answers in seconds.
Probe reads code semantically -- understanding functions, classes, dependencies, and call graphs -- not just doing text search. It pulls context from linked Jira tickets, PRs, and historical decisions to give you the full picture of why code exists, not just what it does.
Every PR gets a thorough first-pass review -- automatically, consistently, before your teammate even looks at it.
Generic AI code review tools don't know your team's conventions. They don't know that error handling must use the custom AppError type, that database queries must go through the repository layer, or that touching the billing module requires extra scrutiny.
Probe learns your team's patterns and applies them to every PR. It catches security vulnerabilities, performance regressions, breaking API changes, and cross-service dependency issues. It explains why something is flagged, suggests a fix, and links to the relevant code.
See how your change affects the entire system, not just the file you're editing.
Real systems aren't single repos. They're dozens of services with shared libraries, event buses, and cross-cutting dependencies. A renamed field in one service can break deserialization in three others. A changed API response format can silently corrupt data downstream. Traditional tools can't see this.
Probe maps the entire system. It understands service boundaries, data flows, event subscriptions, and API contracts. Before you push, you know exactly what your change touches -- across every repo, every service, every consumer.
Pre-built automation workflows you can deploy immediately. Customize per repo. Version like code. Improve over time.
Every PR gets a first-pass review for security issues, performance problems, style violations, and breaking changes. Customizable rules per repo. Catches what linters miss because it understands the full codebase context.
Point Probe at any repo and get an instant architecture overview, entry points, key abstractions, and how things connect. Cut onboarding time from weeks to hours. Works even when documentation doesn't exist.
From error message to root cause in minutes. Probe traces the code path, identifies relevant recent changes, checks for related issues, and suggests the fix. No more spending hours reading code you've never seen.
Before you push, know exactly what your change affects. Probe traces dependencies across repos, identifies consumers of changed APIs, and flags potential breaking changes. Ship with confidence.
Everything runs on your machine. Your code never leaves your environment. No cloud indexing, no data exfiltration, no compliance headaches.
Use Claude, GPT, open-source models, or your company's self-hosted LLM. No vendor lock-in. Switch providers without changing your workflow.
OpenTelemetry instrumentation captures every query, every workflow run, every decision. Export to Datadog, Grafana, or Splunk. Debug AI workflows like code.
The core engine is open source and auditable. You can read exactly how your code is being processed. No black boxes between you and your tools.
Start with the open-source CLI to try it on your current project. Scale to enterprise when you need multi-repo intelligence and team workflows.

Everything in Open Source, plus multi-repo intelligence, automated workflows, and integrations with your team's existing tools.
Two phases: validate the technology in 10 minutes with open source, then unlock the full platform for your team.
Pick any of these and have something running before your next standup. No account required.
Get codebase-aware intelligence in Claude Code, Cursor, or any MCP-compatible tool. Probe becomes a specialized agent that finds the right context and reduces hallucinations with bounded, structured retrieval.
Add a GitHub Action that reviews every PR for security, performance, and quality. Inline comments with explanations and suggested fixes. Fully customizable rules per repo.
Deploy a Slack bot that answers questions about your codebase. Ask questions in Slack and get answers grounded in actual code -- no context switching to your IDE.
Once you've validated the technology, roll it out to your team with multi-repo intelligence, automated workflows, and integrations with your existing tools.
Point Probe at your team's repos. It builds a system-wide understanding of how services connect, what depends on what, and how data flows.
Define your team's coding standards, security requirements, and architectural patterns. Rules live in the repo, version like code, and evolve over time.
Connect Jira, Slack, and your monitoring stack. Probe pulls ticket context into code answers and posts automated analysis where your team already works.
Track onboarding time for new team members, PR review cycles, and time-to-resolution for bugs. Most teams see 50-70% reduction in onboarding time within the first month.
Want to see how Probe works on your actual codebase?
Schedule a Technical DiscussionCopilot and Cursor are great at completing code in the file you're editing. They don't understand your system architecture, your team's conventions, or the dependencies between your services. They can't tell you that renaming this field will break deserialization in three other services, or that this function has an undocumented side effect that triggers a webhook.
Probe understands the entire system -- across all repositories, with full dependency awareness and historical context. It's the difference between autocomplete and actual understanding.
No. The open-source version runs entirely locally. Your code stays on your machine. You choose which LLM provider to use -- including fully self-hosted options. The enterprise version can be deployed on-premises inside your company's infrastructure.
Probe supports all major programming languages through tree-sitter parsers: JavaScript/TypeScript, Python, Go, Rust, Java, C/C++, Ruby, PHP, and many more. It also understands Terraform, Kubernetes YAML, Dockerfiles, and CI/CD configs. AST-aware search works across all supported languages.
Probe uses bounded, structured retrieval -- it searches the actual codebase semantically and returns grounded answers with file paths and line numbers. It doesn't hallucinate code that doesn't exist. When it doesn't know something, it tells you what it searched and what it found. Every answer is traceable back to the source.
