Progressive Delivery Without the Rollback Scramble
Roll out features gradually with feature flags and canary releases so bad deploys affect 1% of users, not 100%.

Release to a subset of users first.
Deploying code and releasing features don’t have to be the same thing. Most teams ship to everyone at once and hope nothing breaks. We implement progressive delivery with feature flags, canary releases, and ring deployments so you can validate with real traffic, catch problems early, and roll back by flipping a switch instead of redeploying.
Our capabilities include:
- Feature flag implementation and management
- Canary release and traffic shifting
- Ring deployment configuration
- A/B testing and experimentation infrastructure
- Kill switch and instant rollback setup
- Flag lifecycle and technical debt management
Who we support
Shipping to everyone at once turns every release into a gamble. We help teams control who sees what so they can validate features with real users before going all-in.
Teams With All-or-Nothing Releases
Every deployment goes to 100% of users immediately. There's no way to test with a subset first. Feature flags let you ship code dark and release to 1% before you release to everyone.
Companies With Painful Rollbacks
When something breaks, rolling back means redeploying, which takes time and coordination. Kill switches let you disable a broken feature in seconds without touching the pipeline.
Organizations Running Blind Experiments
You want to A/B test but lack the infrastructure. Product decisions rely on opinions instead of data. Experimentation frameworks give you real metrics on what actually works.

We offer a wide range of engagement models to meet our clients’ needs. From hourly consultation to fully managed solutions, our engagement models are designed to be flexible and customizable.
Staff Augmentation
Get access to on-demand product and engineering team talent that gives your company the flexibility to scale up and down as business needs ebb and flow.
Retainer Services
Retainers are perfect for companies that have a fully built product in maintenance mode. We'll give you peace of mind by keeping your software running, secure, and up to date.
Project Engagement
Project-based contracts that can range from small-scale audit and strategy sessions to more intricate replatforming or build from scratch initiatives.
We'll spec out a custom engagement model for you

Feature Flag Platforms
Our engineers implement flag management platforms that give you control over who sees what without touching your deployment pipeline.
- LaunchDarkly — Enterprise feature management platform with targeting rules, audit logs, and SDKs for controlling releases across web, mobile, and backend
- Split — Feature delivery platform with built-in experimentation, metric tracking, and automated rollout policies based on performance data
- Flagsmith — Open-source feature flag service with self-hosted and cloud options, remote config, and multi-environment management
- Unleash — Developer-focused open-source platform with flexible targeting strategies, gradual rollouts, and GitOps-friendly configuration
- ConfigCat — Lightweight flag management with instant propagation, percentage rollouts, and integrations for teams that want simplicity
- Harness Feature Flags — Feature management integrated with CI/CD pipelines, governance controls, and automated rollback on metric degradation
Experimentation & A/B Testing
Curotec configures experimentation infrastructure that lets you test variations with real users and measure what actually works.
- Optimizely — Enterprise experimentation platform with A/B testing, multivariate experiments, and AI-powered personalization for product decisions
- VWO — Conversion optimization platform with A/B testing, heatmaps, and session recordings for understanding user behavior and validating changes
- Statsig — Product experimentation platform with automated statistical analysis, feature gates, and real-time metrics for data-driven releases
- Eppo — Warehouse-native experimentation tool that runs analysis on your existing data stack for accurate, trustworthy experiment results
- GrowthBook — Open-source A/B testing platform with Bayesian statistics, feature flags, and integrations with your analytics warehouse
- Amplitude Experiment — Experimentation tied to product analytics so you can target cohorts, run tests, and measure impact in one platform
Canary Release & Traffic Shifting
We set up progressive rollout tools that route traffic percentages to new versions and roll back automatically on failures.
- Argo Rollouts — Kubernetes controller for canary deployments, blue-green releases, and automated rollback based on metrics from Prometheus or Datadog
- Flagger — Progressive delivery operator that automates canary analysis, traffic shifting, and promotion with service mesh and ingress integration
- Istio — Service mesh with traffic splitting, weighted routing, and fine-grained control over which percentage of requests hit new versions
- AWS App Mesh — Managed service mesh for gradually shifting traffic between task versions in ECS and EKS with built-in health checks
- Linkerd — Lightweight service mesh with traffic splitting capabilities for canary releases without the complexity overhead of heavier meshes
- Spinnaker — Multi-cloud continuous delivery platform with canary analysis, automated rollback, and deployment strategies across cloud providers
Release Observability
Our teams integrate monitoring that tracks release health so you know when to advance, hold, or roll back based on real data.

FAQs about our progressive delivery
How is progressive delivery different from CI/CD?
CI/CD gets code to production. Progressive delivery controls who sees it after deployment. You can deploy a feature to all servers but only release it to 1% of users. They work together — CI/CD handles the pipeline, progressive delivery handles the rollout.
Do feature flags add latency to our application?
Not with proper implementation. SDKs evaluate flags locally using cached rules, so decisions happen in microseconds without network calls. We configure streaming updates so flag changes propagate in seconds without polling overhead.
How do we avoid feature flag debt?
Flags should have owners, expiration dates, and removal plans from day one. We implement lifecycle tracking that shows which flags are stale, who owns them, and when they were supposed to be cleaned up. Temporary flags don’t become permanent.
Can we use progressive delivery without a service mesh?
Yes. Feature flags work at the application layer and don’t require infrastructure changes. You can start with simple percentage rollouts in your code, then add canary releases and traffic shifting later as your practices mature.
How do we know when to advance or roll back a release?
We tie rollouts to metrics you already track — error rates, latency, conversion. You define thresholds, and releases advance automatically when metrics stay healthy or roll back when they degrade. No more guessing.
What if we already have some feature flags in our code?
Most teams do, usually inconsistent implementations scattered across services. We consolidate existing flags into a managed platform, standardize evaluation patterns, and clean up the ad-hoc toggles that have accumulated.
