Pros and cons
Zed
Coding · free
Pros
- ✓Exceptional speed — fastest modern code editor available, with sub-millisecond input latency
- ✓Parallel agents let you run multiple AI tasks at once without blocking your workflow
- ✓No AI subscription lock-in — use any model provider with your own API keys
- ✓Built-in real-time collaboration with voice chat, no extensions needed
Cons
- ×Smaller extension ecosystem compared to VS Code-based editors like Cursor
- ×BYOK model means more setup friction — you need API keys before AI features work
- ×No Windows support yet — currently macOS and Linux only
- ×Fewer built-in language integrations than mature IDEs like JetBrains
Codex Security CLI
Coding · free
Pros
- ✓Genuinely open source — you can read the client, audit its calls, fork it, and pin a version rather than trusting a black-box security vendor
- ✓Tracks findings across runs, so a scan reads as a delta instead of the same wall of unranked issues every build
- ✓Verifies that fixes actually closed the finding, which is what makes it viable as a CI gate rather than a report-only scanner
- ✓Model-based analysis can follow logic across files without someone first writing a rule for that specific pattern
- ✓Free at the tool layer, which puts real scanning in reach of teams shipping AI-generated code with no security budget
Cons
- ×Day-one release in early access — the command surface and flags will churn, so pin the version before it gates anything
- ×The client is open but the model that ranks a finding as critical or noise is not, and neither is the eval set behind it
- ×Same-vendor auditing: Codex writes the code and a Codex-branded tool grades it, with no public study of whether same-family generator and auditor share blind spots
- ×Whether your unpatched inventory stays on the runner or leaves it is worth establishing from the source before wiring this into a pipeline
