Flag Management

Control what ships, when it ships, and who sees it.

Gradual Rollouts

Roll out to 1% of users, then 10%, then everyone. Deterministic hashing ensures consistent assignment. Roll back to 0% in one click.

A/B Testing & Variants

Run experiments with string, integer, or JSON variants. Weighted distribution across variants with consistent user assignment.

Kill Switches

Something broke? Disable the feature in 200ms. No deploy, no waiting, no downtime. Propagates to all connected SDKs via SSE.

Multi-Environment

Separate flag configurations per environment. Test in staging, ship to production. Each environment gets its own API key and state.

Targeting & Segments

Show the right feature to the right user at the right time.

Context-Based Targeting

Target by any evaluation context attribute, user ID, email, region, plan, custom properties. Rules evaluate server-side, so targeting logic stays out of your client code.

Segments

Define reusable user groups: beta testers, enterprise customers, internal team. Apply a segment to any flag without redefining rules.

Targeting Rules

Chain multiple conditions with AND/OR logic. String equals, contains, regex. Numeric comparisons. Semantic versioning. Prioritized rule ordering with fallback defaults.

Integrations

Connect Flipswitch to the tools your team already uses.

Webhooks

Get notified when flags change. HMAC-SHA256 signed payloads to your endpoint. Use them to trigger deploys, invalidate caches, or update downstream systems.

Slack

Flag change notifications in your Slack channels. Know when someone enables a flag or updates targeting rules without checking the dashboard.

MCP Server

Manage flags from Claude Code, Cursor, or any MCP-compatible AI tool. Create flags, toggle environments, and check status without leaving your editor.

REST API

Full admin API for automation. Manage flags, environments, and projects programmatically. OpenAPI spec included for client generation.

Open Standards

No vendor lock-in. Switch providers without rewriting evaluation code.

OpenFeature Native

Flipswitch implements the full OpenFeature specification. Use the standard OpenFeature SDK in your application. Same API regardless of provider.

OFREP Protocol

OpenFeature Remote Evaluation Protocol. A standard HTTP API for flag evaluation that any conformant provider can implement. No proprietary wire format.

Multi-Language SDKs

First-class SDKs for every major platform. Type-safe, idiomatic, built for each ecosystem.

JS Python Go Java .NET Rust Swift PHP Ruby

Infrastructure

Fast, reliable flag evaluation at the edge.

Edge Network

Deployed to edge nodes worldwide. Flag evaluations happen close to your users, not in a single region.

Real-Time SSE

Flag changes propagate to connected SDKs in milliseconds via Server-Sent Events. No polling, no stale cache, no delay between toggle and effect.

Resilient by Default

SDKs cache the last known configuration locally. If the network drops, evaluation continues with cached values. Your app never blocks on a flag check.

Analytics Dashboard

See which flags are evaluated, how often, and by whom. Track SDK connections, evaluation counts, and flag usage across environments.

Team & Security

Built for teams that care about who can change what.

RBAC

Fine-grained, resource-based access control at the project level. Admins, editors, and viewers. Control who can toggle production flags.

Audit Logs

Every flag change is recorded: who changed what, when, and from which value. Full history for compliance and debugging.

API Key Management

Separate API keys per environment. Rotate keys without downtime. Server-side keys for admin access, client-side keys for SDK evaluation.

Team Management

Invite team members to your organization. Assign roles per project. Manage access from one place.
