incident.io vs Semgrep: at a glance
What is incident.io?
incident.io's Nexus agent now takes in your internal tools as well as going out to your editor.
Investigations, the agent that posts a root-cause hypothesis when an incident opens, is the center of incident.io; it went GA and then doubled its speed in September. Last week the company shipped a plugin that puts its agent skills into any coding harness. The newest release, Extensions, goes the other way: teams can feed Nexus their own debugging knowledge and connect internal or third-party tools to it.
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.

◆ Current state
Investigations, the agent that posts a root-cause hypothesis when an incident opens, is the center of incident.io; it went GA and then doubled its speed in September. Last week the company shipped a plugin that puts its agent skills into any coding harness. The newest release, Extensions, goes the other way: teams can feed Nexus their own debugging knowledge and connect internal or third-party tools to it.
◆ Where it's heading
incident.io is turning its agent into a two-way integration point. The plugin exports its skills into developers' agents, and Extensions imports a company's own tools and context into Nexus. Dashboards, ticket sync and alert routing keep incident.io as the record those skills read from and write to.
◆ Prediction
Expect worked examples or templates for common Extensions, such as internal deploy or feature-flag tools, and Investigations results that cite data pulled through them. The entries do not say how Extensions are built or whether they cost extra.
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.
