![Best Thirdweb Alternatives [2025]](https://blog-cms.openfort.io/uploads/thirdweb_alternatives_0de0304e72.png)
In the rapidly evolving landscape of web3 development, having comprehensive tools and SDKs is essential for building robust decentralized applications. Thirdweb is a developer platform offering tools and SDKs to help you build and deploy web3 applications across EVM-compatible chains. One of its biggest value-adds is its library of prebuilt, extensible smart contracts and its SDKs for integrating with them.
However, depending on your needs—especially if you're building a more wallet-centric experience, need custom authentication, or want to control more of your wallet infrastructure—there are several compelling alternatives worth evaluating. This article explores the top Thirdweb alternatives developers are choosing in 2025.
1. Openfort
Openfort (that's us 👋) is an open-source wallet infrastructure and ecosystem SDK designed for developers who want full control over their wallet experiences. Unlike Thirdweb's broad web3 platform approach, Openfort specializes in enabling teams to build and embed smart wallets into apps and games, with a focus on user experience, interoperability, and extensibility.
Openfort is not just another wallet SDK—it's a fully open wallet framework with a modular set of tools that gives developers complete control over their wallet infrastructure without vendor lock-in.
Key Features
Compared to Thirdweb, Openfort takes a more modular, self-sovereign approach with open-source tooling from end to end. The stack includes:
Smart Wallet Infrastructure: Fully self-custodial smart account infrastructure with native support for ERC-4337 and EIP-7702, enabling advanced features like session keys and transaction batching.
Open Source and Self-Hostable: Complete MIT-licensed stack where you can audit and control every component, including the ability to host on your own infrastructure for maximum sovereignty.
Comprehensive Developer Toolkit: UI hooks, popup management, transaction workflows, and extensible session support for building cross-app wallet experiences.
Custom Authentication Support: Integrate your own Auth0, Firebase, or custom authentication providers without vendor lock-in or platform restrictions.
Multi-Platform SDKs: Native support for Unity WebGL, Telegram mini-apps, React Native, and web environments for web3 wallet gaming and consumer applications.

Building In-House Wallet Product
In the realm of wallet infrastructure, organizations often face the decision of choosing between off-the-shelf solutions like Openfort or Thirdweb and developing an in-house wallet platform tailored to their specific needs. While this option can offer high customization, it comes with its own set of challenges and considerations.
Pros of Building an In-House Wallet Solution
Complete Control: The most significant advantage of an in-house solution is the ability to tailor it precisely to your web3 application needs. This customization can result in a wallet system that aligns perfectly with your existing workflows, brand, and user experience requirements.
No Vendor Lock-in: With an in-house system, you have complete control over your wallet infrastructure without dependency on external providers or their pricing changes.
Custom Features: You can build specific features for your use case, whether it's web3 wallet gaming, web3 wallet DeFi, or web3 wallet AI agents.
Cons of Building an In-House Wallet Solution
Resource-Intensive Development: Developing a wallet solution in-house requires significant time investment in design, development, and testing. This process can divert valuable engineering resources away from your core product development.
Security Expertise Requirement: Building a secure wallet system requires deep cryptographic and blockchain security expertise. This includes not just the initial build but also ongoing threat assessment and response capabilities.
Ongoing Maintenance and Support: Post-deployment, the system will require continuous maintenance to ensure security, performance, and compatibility with evolving blockchain standards. This includes regular updates, patches, and security audits.
Compliance and Audit Challenges: Custom-built wallet systems can face heightened scrutiny from auditors and regulators. Ensuring compliance with evolving regulations can be more challenging compared to using established commercial solutions.
Scalability Concerns: As your application grows, the in-house wallet solution might need significant re-engineering to scale effectively, which can be a resource-intensive process.
Time to Market: Building a production-ready wallet infrastructure can take months or years, potentially delaying your core product launch.
