Best Privy Alternatives [2025]

In the world of web3 apps, seamless user onboarding and secure wallet infrastructure are critical. Privy is a well-known embedded wallet and authentication provider used by many developers. But depending on your stack and needs, there are several alternatives that may better suit your project. This post explores some of the top Privy alternatives developers are choosing in 2025.

1. Openfort (that’s us 👋)

Openfort is an open-source wallet infrastructure platform designed for web3 applications. Unlike Privy, which focuses primarily on onboarding and user identity, Openfort offers a complete wallet infrastructure SDK. It supports smart accounts (ERC-4337 and EIP-7702), embedded wallets, and custom authentication—giving developers full control over the user experience.

Openfort is particularly popular among projects building their own wallets or game-specific onchain economies. With its ecosystem SDK, Openfort enables teams to create self-custodial flows that are composable and extendable.

Key Features:

• Embedded and in-app wallets with support for passkeys, social login, and email
• Smart contract account infrastructure (ERC-4337, EIP-7702)
• Open-source and self-hostable under MIT License
• Ecosystem SDK: Easily build your own wallet SDKs with UI components and a communication bridge
• Works across all EVM-compatible chains
