carrier vs Semgrep
A side-by-side editorial comparison of carrier and Semgrep — release velocity, themes, recent moves, and the top alternatives to consider.
carrier vs Semgrep: at a glance
What is carrier?
carrier's 0.3.0 quietly rewrites how crated functions see each other — and breaks code that relied on the old rules.
carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.
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.

carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.
◆ Where it's heading
Each release tightens the boundary between a crate and its surroundings. 0.2.0 introduced .parent_env defaulting to baseenv() to cut the crate off from the global search path and made unnamed ... arguments an error instead of a silent drop; 0.3.0 finishes the job by controlling the environment chain of the packed closures themselves. The package is trading backwards compatibility for predictable, self-contained payloads — a reasonable bet for something whose failures otherwise surface on a remote worker.
◆ Prediction
The 0.1.0 notes promised an automatic dependency-detection mode to replace explicit packing; nothing since has delivered it, and with the environment semantics now settled that is the obvious next move — though the entries give no date for it.
Semgrep
5.0INFRA · APIS
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.
