Reviewer scorecard
“Deno 2's Node.js compatibility changes everything. Secure by default, great tooling, and now practical for real projects.”
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“Deno 2 finally delivers on the promise. npm compatibility means you can actually use it without friction.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“Security-first runtime design is correct for the AI era where you're running untrusted code. Deno Deploy is compelling.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
