ONE REQUEST. ONE DECISION.
See exactly how a flag becomes an answer.
Every evaluation moves through the same controlled path, from flag lookup to a deterministic result for the current user.
Evaluation flow: Maxlona loads the feature flag and its environment configuration, assigns the user to a stable rollout bucket, evaluates targeting rules, selects the matching variant, and returns true.

CONTROL EVERY RELEASE
Build confidence into the way you ship.
Maxlona gives product and engineering teams a clear control plane for every Feature Flag.
Release safely
Deploy code separately from feature activation. Validate in smaller steps before a wider release.
Roll back instantly
Disable a Feature Flag without another application deployment when a release needs attention.
Target precisely
Release by Environment, Segment, user attribute, Targeting Rule, or Percentage Rollout.
Track changes
Use the Audit Log to see who changed a flag, what changed, and when it happened.
ONE PLACE TO MANAGE RELEASES
Every change has a clear next step.
Move from the first test to production with controls your whole team can understand.
Target the right users
Use environments, segments, user attributes, and percentage rollouts to shape each release.
Roll back quickly
Turn off a feature without waiting for another application deployment.
Keep decisions visible
Review approvals and audit history so your team knows who changed a flag and when.
OUR MISSION
Deployment should not automatically mean release.
Maxlona makes feature management accessible across engineering, product, operations, marketing, sales, and project teams — because release workflows involve more than developers.

DELIVERY OPTIONS
Choose how your applications receive and evaluate feature state.
Choose HTTP evaluation, webhooks, streaming, or combine them to fit your application.
HTTP evaluation
Call POST /flags/<name> with a Management Key when your application needs a flag value.
Webhooks
Send change notifications to configured endpoints and inspect their delivery history.
Realtime Streaming
Use a streaming connection at /hubs/flags to receive flag-change notifications.
ENVIRONMENT MANAGEMENT
One Feature Flag. The right state in every Environment.
Move safely from development to production without copying configuration or losing the release context.

CORE CAPABILITIES
Feature controls for different release workflows.
Use boolean toggles, multi-variant experiments, targeting rules, and percentage rollouts.
Performance Metrics
Review per-flag traffic, variant breakdowns, environment splits, and traffic heatmaps.
A/B Test Analysis
Record conversion events and review significance results by variant.
A/B testing guide →Realtime Streaming
Subscribe to flag-change notifications through streaming.
Realtime updates docs →Kill Switch
Suspend evaluation by environment, application, or both without changing unrelated flags.
Kill switch docs →Gradual Rollouts
Set percentage allocations and use deterministic bucketing for consistent assignment.
Percentage Rollout guide →Webhook Delivery
Configure webhook endpoints and inspect delivery history.
Webhooks docs →Approval Workflows
Configure approval requirements and review pending flag changes.
Approval workflow docs →JSON Tester
Submit an evaluation payload and inspect the returned variant and evaluation reason.
Feature Flags docs →Change Log
Review recorded changes and export available history as CSV or JSON.

Get started in four steps.
Sign up
Create an organization to begin.
Create a flag
Pick a template — boolean, % rollout, A/B, or kill switch — and tweak the variants.
Generate API key
One key per (app, env). Add it to your service configuration.
Evaluate
Call POST /flags/{key} with an evaluation payload.
Ready when you are
Ship confidently.
Reverse instantly.
Control every release from one place. Roll out gradually, watch impact in real time, and switch back safely when plans change.
