A/B testing made easy

Roll out features to select users without having to push code live

Features

Type-Safe Configuration Database

Create a database for Typescript configuration and make changes without redeploying.

Full IDE (Cursor, Windsurf, VSCode) support
Compile-time type checking
Deploy any configuration: feature flags, A/B tests, LLM configs

Runtime Schema Validation

Validate your configs in runtime with Zod. Typeconf automatically generates Zod schemas for all your configs.

Made by builders, for builders

Typeconf is created by experienced engineers who have been in your shoes. We know what you need, we build the tools - you build the product.

NPM Integration

Share configs between projects using NPM packages, and version control them like code. We're also building a library of configurations that you can use in your projects.

Multi-Platform Support

Python, Kotlin, and Swift support coming soon. Sync your configs everywhere - frontend, backend, and mobile.

AI Ready

Type-safe configuration will protect you from LLM hallucinations. MCP is coming soon!

Coming Soon: Secrets

Integrating with your secrets manager to store and read secrets with type safety.

Use Cases

Product Configuration

Feature flags, user settings, and product parameters

Quickly iterate on your LLM prompts

Types

model AgentConfig {
  prompt: string;
  temperature: int32;
  maxTokens: int32;
  searchDepth: int32;
  searchUrl: string;
}

Values

let agentConfig: AgentConfig = {
  prompt: `You're an assistant
    that searches the web to
    improve configurations
    of software across the world.`,
  temperature: 0.5,
  maxTokens: 10000,
  searchDepth: 10,
};

Service Configuration

API endpoints, business rules, and service settings

Define and manage API endpoints with type safety

Types

model APIConfig {
  endpoints: Record<{
    url: string;
    method: "GET" | "POST";
    timeout: int32;
    retries: int32;
  }>;
  rateLimiting: Record<{
    requests: int32;
    window: string;
  }>;
}

Values

let api: APIConfig = {
  endpoints: {
    "users": {
      url: "/api/v1/users",
      method: "GET",
      timeout: 5000,
      retries: 3
    }
  },
  rateLimiting: {
    "default": {
      requests: 100,
      window: "1m"
    }
  }
};

Infrastructure Configuration

Deployment settings, networking, and infrastructure parameters

Manage infrastructure and deployment settings

Types

model Deployment {
  replicas: int32;
  resources: Record<string>;
  environment: "dev" | "prod";
  scaling: Record<{
    min: int32;
    max: int32;
    target: int32;
  }>;
}

Values

let deployment: Deployment = {
  replicas: 3,
  resources: {
    "cpu": "2",
    "memory": "4Gi"
  },
  environment: "prod",
  scaling: {
    "default": {
      min: 2,
      max: 10,
      target: 5
    }
  }
};

Looks very interesting, will give it a go. What are the other languages you plan to support and what would be the use cases of shared types between languages? This might be super powerful in microservices architecture, have you thought about it?

u/TheMightyMegazord

This seems interesting, but how can I use it in projects that aren't using TS/JS?

u/laggingtom

Looks great! I have to ask tho: is the plan with the "free cloud storage" for configs to eventually start charging?

u/Alkanste

Thanks for your info, I’ll look into it! So it is a safe way to toggle feature flags, right?

in/maddiewang

Def want to start integrating typeconf for feature flags, cuz i want some users to see the reddit montioring feature, and others just to see the linkedin posting feature

@WillJin1796

Will: someone invent ai infra so i can yell at aws and have impact me: what kind of infra do you want? :) Will: one that uses typeconf! and honestly it would be pretty cool if there was an agent that could provision your cloud stack by analyzing your code

u/lesbianzuck

Wow I’m curious how to use it. I want to use it for feature flagging. I keep adding UUIDS to my GitHub code and then pushing it live. Sometimes I’m in the middle of coding something and it’s horrible having to rebuild, rollback, if there’s a bug…. Much rather be able to update a config. For my marketing copy or uuids to test features…

in/ikechigriffith

I’ll check it out

sudosteph

me: I feel like I should just be able to generate k8s configs from Typescript with Typeconf if I add all the types there, is anyone interested in this? sudosteph: Yes. CDK has made me a fan of Typescript.

I’ll check it out
