Cosmic vs Semgrep
A side-by-side editorial comparison of Cosmic and Semgrep — release velocity, themes, recent moves, and the top alternatives to consider.
Cosmic vs Semgrep: at a glance
What is Cosmic?
Cosmic retired AI Studio and gave its agents goals — the CMS is becoming an agent runtime.
Six weeks of releases pull in one direction. AI Studio was retired and Cosmic's AI consolidated into three surfaces: Agents, Workflows, and Code. Agents gained goals described in plain language that they work toward on their own, running steps and checking in, plus write access to reusable rich-text Content Blocks rather than read-only reference. Semantic search embeds bucket objects into a vector index so content is retrievable by meaning. The two newest entries add Claude Opus 5 and Kimi K3 to the model lineup.
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.

Cosmic retired AI Studio and gave its agents goals — the CMS is becoming an agent runtime.
◆ Current state
Six weeks of releases pull in one direction. AI Studio was retired and Cosmic's AI consolidated into three surfaces: Agents, Workflows, and Code. Agents gained goals described in plain language that they work toward on their own, running steps and checking in, plus write access to reusable rich-text Content Blocks rather than read-only reference. Semantic search embeds bucket objects into a vector index so content is retrievable by meaning. The two newest entries add Claude Opus 5 and Kimi K3 to the model lineup.
◆ Where it's heading
The content API is turning into a runtime agents operate inside: goals instead of prompts, write permissions instead of suggestions, and a vector index so an agent can find what it needs without being handed it. Retiring AI Studio is the clearest signal — Cosmic is choosing fewer, deeper surfaces over a menu of separate AI features, which is a harder position to reverse.
◆ Prediction
Expect agent write scope to extend past Content Blocks to objects and media, and goals to gain triggers or schedules so they run without a person starting them.
Semgrep
5.0INFRA · APIS
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.
