Semgrep vs Skipper
A side-by-side editorial comparison of Semgrep and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
Semgrep vs Skipper: at a glance
What is Semgrep?
Semgrep adds Objective-C as an alpha target, its first new language since Dart went GA.
Semgrep ships weekly on two tracks. Supply Chain added Bazel Maven workspaces in 1.177, Bun lockfiles in 1.179 and unpinned Python requirements in 1.181. The matcher promoted Dart to GA in 1.180. 1.182 adds Objective-C (alpha) with search- and taint-mode rules, and updates the C# Pro, Terraform HCL and Lua grammars.
What is Skipper?
Skipper patches its second filter advisory in a week, this one in the OPA request-body filter.
Skipper keeps tagging one release per merge. v0.28.46 fixes advisory GHSA-j3r3-rjcc-vh4q in the opaAuthorizeRequestWithBody filter, reported by an outside researcher, a week after the cache() advisory fix. Between them came v0.28.40's priority routes for binary users, raw-path predicates, and fixes for a JWT cache leak, a headerToQuery bug and an AWS signer data race; v0.28.45 only repairs CI test targets.

Semgrep

Semgrep adds Objective-C as an alpha target, its first new language since Dart went GA.
◆ Current state
Semgrep ships weekly on two tracks. Supply Chain added Bazel Maven workspaces in 1.177, Bun lockfiles in 1.179 and unpinned Python requirements in 1.181. The matcher promoted Dart to GA in 1.180. 1.182 adds Objective-C (alpha) with search- and taint-mode rules, and updates the C# Pro, Terraform HCL and Lua grammars.
◆ Where it's heading
Language coverage is widening toward Apple-platform code, where .m files have so far sat outside Semgrep's rules, and Objective-C++ is promised separately. On the dependency side, Python requirements handling keeps moving toward how people write manifests by hand rather than how pip-compile emits them.
◆ Prediction
Expect Objective-C++ (.mm) support next, as the 1.182 notes say, and Objective-C moving out of alpha. The open item from 1.181, turning unpinned Python deps into findings, has no date yet.
Skipper
5.0INFRA · APIS
Skipper patches its second filter advisory in a week, this one in the OPA request-body filter.
◆ Current state
Skipper keeps tagging one release per merge. v0.28.46 fixes advisory GHSA-j3r3-rjcc-vh4q in the opaAuthorizeRequestWithBody filter, reported by an outside researcher, a week after the cache() advisory fix. Between them came v0.28.40's priority routes for binary users, raw-path predicates, and fixes for a JWT cache leak, a headerToQuery bug and an AWS signer data race; v0.28.45 only repairs CI test targets.
◆ Where it's heading
Security hardening at the routing layer is the main thread: outside researchers are reporting filter-level advisories, and the maintainers are answering with fixes plus tools like priority routes that let operators block suspicious paths before any backend sees them. Around that, correctness fixes for concurrency and lifecycle bugs keep landing one tag at a time, and CI coverage is being repaired so race tests actually run.
◆ Prediction
Expect more advisory fixes in filters that inspect request bodies or paths, and more single-fix tags. The entries don't say whether the advisory details will be published with them.
