What is Semgrep?

Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.

Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

What is webfakes?

A fake web server for tests that keeps closing the gap with the real thing.

webfakes runs a real HTTP server inside R tests so packages can exercise network code without hitting the internet. Its releases follow a consistent logic: find a class of behaviour that only the real internet could reproduce, then implement it locally. HTTPS arrived in 1.4.0; before that the httpbin clone reached full parity with the Python original, and a fake git HTTP server landed alongside CGI middleware. The most recent release, 1.5.0, is about the server's own rough edges — keep-alive timeouts, locale-independent HTTP date parsing, and trailing-slash route matching.

Semgrep vs webfakes: editorial side-by-side

5.0

Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.

◆ Current state

Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

◆ Where it's heading

The performance work is converging on one problem: very large monorepos. File targeting now batches path filtering across worker domains, rule parsing shards by bytes instead of worker count, and a new Pro memory policy lets a scan trade RAM for skipping on-disk caching. Running alongside it is a quieter thread of trust work, and the 1.173.0 fix for silently dropped targets belongs to it: a file whose path filtering failed appeared in neither the findings nor the skipped list, which is the kind of gap that undermines a scan report more than any missing rule.

◆ Prediction

Expect the parser-refresh-plus-throughput cadence to continue, with the memory policy and the dependency-path output likely graduating out of experimental once large-repo users report back on them.

A fake web server for tests that keeps closing the gap with the real thing.

◆ Current state

webfakes runs a real HTTP server inside R tests so packages can exercise network code without hitting the internet. Its releases follow a consistent logic: find a class of behaviour that only the real internet could reproduce, then implement it locally. HTTPS arrived in 1.4.0; before that the httpbin clone reached full parity with the Python original, and a fake git HTTP server landed alongside CGI middleware. The most recent release, 1.5.0, is about the server's own rough edges — keep-alive timeouts, locale-independent HTTP date parsing, and trailing-slash route matching.

◆ Where it's heading

The package is converging on being indistinguishable from a real server for test purposes, which is the only way it stays useful — every unsupported protocol feature is a piece of code someone cannot test offline. The remaining work has visibly shifted from missing endpoints to correctness details: date header parsing under unusual locales, keep-alive tuning, request body handling across content types.

◆ Prediction

Expect continued fidelity work against real-server behaviour rather than new app types, with HTTP/2 or authentication schemes the most plausible next gaps given the direction HTTPS opened. The entries do not indicate a specific planned feature.
