Targeted delivery, zeroed in

Roll out features to the right users at the right time. Target by user, region, or custom attributes and control who sees what. Built-in permissions and approvals keep every release secure and intentional.

Guardrails for every release

Roll out gradually, monitor in real time, and act fast if something changes. Pause, roll back, or shut it off instantly. Built-in safeguards protect your users before issues turn into incidents.

Move at the speed of your ideas

Let AI agents handle the heavy lifting. Generate variables, adjust logic, and personalize experiences in real time. You stay in control while your product keeps moving.

Lifecycle is our lifestyle

More than on/off. Optimizely manages every stage of a feature’s life from the first dark launch to the final flag cleanup.

Progressive rollouts

Start at 1%. Move to 10%. Go to 100% or hold at 50% and measure. Ramp traffic at your pace, with targeting rules that go safely far beyond percentage-based splits.

Instant kill switch

Something breaks in production? Disable the flag from the dashboard. No redeploy. No incident at 2am. Features go dark in seconds, not hours.

Placeholder

Dynamic configuration

Ship the flag once. After that, product and content teams can update copy, limits, thresholds, and pricing tiers at runtime without touching code.

Flag governance and lifecycle

See every flag, who owns it, the status, and which environment it's running in. Mutual exclusions keep experiments clean and your results trustworthy.

Control across your stack

Backend and microservices

Keep flag decisions in your infrastructure. Use SDKs or APIs to evaluate and control releases across any service, in any language.

Mobile

Update features instantly without waiting for app store approvals. Changes go live to users as soon as you’re ready.

Edge

Run flag evaluations at the edge for fast, consistent experiences. Deliver the right experience before the request is even completed.

Supported environments

Ship anywhere your code runs. Every SDK is built for sub-millisecond local evaluation where decisions happen in process, not over a network call. No added latency. No flicker.

We've put Optimizely experimentation as part of our definition of done. When we launch a new feature, you enable it for experimentation — it's a requirement, not an option.

Secret Escapes can't afford to make changes on a whim that disrupt this momentum. That's why they run experiments on all app and website changes before rolling them out live.
