Is ZCode safe? What the open-sourced code shows
Z.ai open-sourced ZCode after it was caught uploading .git histories. We read the source: what the changelog won't say, and one default to change before CI.

AGENTS.md vs CLAUDE.md: which file Claude Code reads now
Claude Code 2.1.277 reads AGENTS.md when there's no CLAUDE.md. We tested 17 setups: a CLAUDE.local.md or DISABLE_TELEMETRY quietly turns it off.

Using any LLM with Codex CLI: what the proxy sends

Is OpenCode private by default? Reading the source
Two privacy claims about OpenCode get repeated everywhere. We read the source at tag v1.18.28: one is stale, the other is narrower than it sounds.
Tested in real projects
We use these tools on actual codebases — not feature checklists or marketing demos.
No pay-to-play
Rankings and verdicts are never for sale. Affiliate links never change our opinion.
Kept current
AI tooling moves fast. We revisit and update reviews as products ship changes.
Engineer's perspective
Written from the point of view of people who ship software for a living.
