A free, anonymous Software Composition Analysis platform built on the principle that knowing what's in your dependencies shouldn't require handing your code to a vendor.
Modern applications are 80–90% third-party code. The open-source ecosystem makes teams dramatically more productive, but it also means every dependency you add carries its own history of bugs, security flaws, abandoned maintainers, and license obligations.
The good dependency scanners want an account. They want to connect to your repository. They upload your project to their cloud. The free tiers hide the features that actually matter — like exploitability-based prioritisation — behind a paywall.
DepWarden is built to remove that friction. Paste a manifest, get a complete analysis. No account, no binaries, no sign-up flow. The private, session-isolated workspace means your dependency list is yours and nobody else's.
DepWarden combines Software Composition Analysis (SCA) and Static Application Security Testing (SAST) in one free, anonymous workspace.
On the SAST side, DepWarden's static analysis engine scans your source code across 15 languages (JavaScript, TypeScript, Python, Java, Go, PHP, Ruby, C, C++, C#, Rust, Kotlin, Scala, Swift, Shell/Bash) plus IaC (Terraform, YAML, Dockerfile), with 300+ rules across injection, hardcoded secrets, weak cryptography, path traversal, SSRF and framework misconfigurations.
Individual developers and open-source maintainers who want a fast, free check without another account. Security engineers doing a first pass on an unfamiliar project. Teams building a CI gate without connecting a vendor to their repository. Compliance teams who need an SBOM, a VEX document and a NOTICE file in one pass.
"Anonymous" is an architectural constraint, not a marketing claim. When you scan, we create a random session identified by an HttpOnly cookie with no personal data. We never receive source code, binaries, or your project structure — only the dependency manifest text you submit. Sessions expire automatically after 30 days, or you can clear them immediately. See the Privacy Policy for details.
