Use it every day

Honestly didn't expect to like it this much. Productivity-focused developer tooling is exactly what I needed, and focused on practical developer productivity. but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: contextual coding suggestions and supports faster iteration cycles. On balance the feature set — especially productivity-focused developer tooling — justifies the 5 stars for our use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on productivity-focused developer tooling, and integrates with coding workflows caught me off guard. still, I'd recommend giving it a real trial.

Q&A

What can I see with just GitHub connected?

Connecting your GitHub org gives you team-level AI adoption signals out of the box — PR throughput, review patterns, and Acceleration Reports — without anyone installing anything else.

Asked by Paulo Cardoso · Sep 1, 2025

Do my engineers have to install anything?

No. GitHub alone unlocks the team dashboard. For richer per-engineer insights (AI Stack, AI Skills, agent activity), engineers can install Zest in Cursor or Claude Code at any time.

Asked by Valentina Marino · Aug 15, 2025

How does Zest help with org adoption?

Adoption charts show who's using AI, how often, and where value is gained. Teams and enterprises can drive toward 100% usage — ensuring everyone benefits.

Asked by Rania Nasser · Jul 10, 2025

Can I try it for free?

Yes. Connect your GitHub org and you'll get the L2 dashboard — leaderboards, AI metrics, and team insights — with no credit card needed.
