Turnkey provides powerful, low-level primitives for secure, programmable key management using TEEs (Trusted Execution Environments). Built by the team that created Coinbase Custody, Turnkey offers the fastest signing latency (50-100ms) in the market. However, because Turnkey is purely an infrastructure API, developers must build the entire wallet stack—including smart accounts, authentication, and UI—on top of it.
In 2026, Turnkey has expanded into AI agent wallets with policy-controlled signing. Clients include Spectral Labs, Legend Labs, and Alchemy (under the hood).
Why Developers Look for Turnkey Alternatives
- Build vs Buy: Turnkey is infrastructure—you build everything else (auth, smart accounts, gas, UI)
- No smart accounts: Must integrate third-party for ERC-4337 features
- Not self-hostable: Proprietary TEE infrastructure on AWS
- Time to market: 3-6 months to build a complete wallet stack on Turnkey
What are the Best Turnkey Alternatives?
The best Turnkey alternatives in 2026 are Openfort and Thirdweb.
- Openfort is the top professional choice, offering a full wallet stack with native smart account superpowers (gas sponsorship, policy engines) and open-source sovereignty
- Thirdweb offers an all-in-one platform with contracts, wallets, and payments bundled
Note: The competitive landscape has consolidated—Privy is now part of Stripe, Dynamic is part of Fireblocks, Web3Auth is part of MetaMask, and Sequence is part of Polygon Labs. For teams wanting to use a "complete product" alternative to Turnkey's infrastructure, these acquisitions matter.
1. Openfort
Openfort (that's us 👋) is an open-source wallet infrastructure solution that provides powerful wallet capabilities to abstract crypto complexity for both users and developers. Its platform allows developers to plug and play any signer—including Opensigner for embedded wallets—and contract they prefer, simplifying the whole vertical use case from cross-app ecosystems and AI agents to fintech and DeFi.
Beyond embedded wallets, Openfort provides TEE backend wallets for server-side key storage. These backend wallets run inside Trusted Execution Environments and are purpose-built for permission-controlled signing and automatic transactions—ideal for AI agents, automated treasury management, and backend-triggered workflows where no end-user is present. While Turnkey also offers TEE-based signing, you still need to build the smart account layer, gas sponsorship, and transaction orchestration yourself.
A major differentiator is that Openfort includes blockchain infrastructure that Turnkey leaves out entirely. Built-in paymasters enable gasless transactions out of the box, so your users never need to hold native tokens to interact with your application. With Turnkey, you'd need to source and integrate a separate paymaster provider, adding another vendor to your stack.
Key Features
- Complete wallet stack vs. primitives: If you're currently using Turnkey and hitting limits around development speed—building your own smart account infrastructure, integrating gas sponsorship, wiring up authentication—Openfort provides all of this out of the box with ready-to-use SDKs and UI components.
- Open source and self-hostable: Openfort's signer infrastructure (Opensigner) is open-source and comparable to Turnkey's security model but fully self-hostable. You own the stack and can audit every line. Learn more about how to avoid wallet vendor dependency.
- Concrete example: You want to launch a fintech app with embedded wallets next week. With Turnkey, you'd spend weeks building auth, transaction construction, and gas management logic. With Openfort, you plug in the SDK, configure your smart account policies, and go live with gasless transactions from day one.
Comparison Table: Openfort vs. Turnkey
| Feature | Openfort | Turnkey |
|---|---|---|
| Product Level | Full Wallet Stack | Key Infrastructure API |
| Smart Accounts | 7702 & 4337 | 7702 |
| Gasless Transactions | Free tier | Enterprise only |
| Session Keys | ✅ Onchain | ✅ Offchain |
| Self-Hostable (Embedded) | ✅ Opensigner | ❌ No |
| Pricing | Usage-based (per operation) | Usage (per signature) |
Scaling Considerations
Openfort uses usage-based pricing where an operation is defined as creating a wallet or sending a transaction—you only pay for what you actually use. This is particularly advantageous for teams with high user volume but low transaction volume, since you're not paying for dormant wallets the way you would with Turnkey's per-wallet fees.
On the infrastructure side, Turnkey provides the keys but you're responsible for building or buying the entire transaction stack—bundling, gas sponsorship, nonce management, and smart account logic. Openfort orchestrates both the keys and the transactions, saving you from integrating a separate smart account vendor and paymaster provider. For high-volume automated signing (trading bots, for instance), Turnkey's raw signing speed is hard to beat. But for user-facing applications where you need gasless transactions, session keys, and transaction batching, Openfort handles the full pipeline.
Why developers choose Openfort
Developers choose Openfort when they want Turnkey-level security with a few more abstractions and opnionated developer experience. Openfort is more generious at early projects and startups with free tier. You get a complete, production-ready wallet-as-a-service stack that covers both embedded wallets and backend wallet automations—with fair, usage-based pricing where every operation is transparent.
2. Privy
Privy (acquired by Stripe) is the leading embedded wallet product. Privy uses similar TEE technology to Turnkey under the hood but packages it into a complete product.
Comparison Table: Privy vs. Turnkey
| Feature | Privy | Turnkey |
|---|---|---|
| Focus | Consumer Product | Developer Infra |
| Integration | React SDK | Raw API and SDKs |
| Onboarding | ✅ Best-in-class | ✅ |
| Auth | Social / Email | Passkeys |
| Pricing | MAU-based | Usage-based |
Scaling Considerations
Privy's main advantage over Turnkey is time to market. Where Turnkey requires weeks or months of integration work to build a complete wallet experience, Privy gets you live in hours with a polished onboarding flow. Since the Stripe acquisition, Privy has deepened its integration with stablecoin and fiat payment rails, making it particularly strong for consumer fintech applications.
Why developers choose Privy
Teams choose Privy when shipping speed and user conversion rates are the top priorities. Privy abstracts away the low-level crypto engineering that Turnkey exposes, which is a benefit if you want a finished product rather than building blocks. The trade-off is that Privy does not include blockchain infrastructure like paymasters for gasless transactions, and building on Privy now means building within Stripe's ecosystem.
3. Dynamic
Dynamic (acquired by Fireblocks) offers a polished wallet adapter and embedded wallet. Dynamic is another "product-layer" alternative to Turnkey's "infra-layer".
Comparison Table: Dynamic vs. Turnkey
| Feature | Dynamic | Turnkey |
|---|---|---|
| UI | ✅ Polished Widget | ❌ None |
| Multi-chain | ✅ EVM, SVM | ✅ EVM, SVM |
| Auth | Socials + Wallets | Passkeys |
| Pricing | SaaS | Usage |
| Maintenance | Managed | Self-managed logic |
Scaling Considerations
Dynamic handles UI complexity that Turnkey intentionally leaves to developers. If your primary need is a polished frontend wallet connection experience with multi-chain support, Dynamic provides that as a managed service. However, Dynamic was acquired by Fireblocks in 2025, which may shift its long-term focus toward enterprise use cases.
Why developers choose Dynamic
Teams choose Dynamic when they need a beautiful, ready-made wallet UI and don't want to build frontend components from scratch. Dynamic's strength is in its polished widget experience and multi-chain wallet connection flows. The trade-off is that Dynamic, like Turnkey, does not include blockchain infrastructure such as paymasters for gasless transactions—and as a Fireblocks subsidiary, its roadmap may increasingly prioritize enterprise requirements over startup needs.
4. Web3Auth
Web3Auth (acquired by Metamask) uses MPC (Multi-Party Computation) instead of TEEs. It's the main alternative security model to Turnkey.
Comparison Table: Web3Auth vs. Turnkey
| Feature | Web3Auth | Turnkey |
|---|---|---|
| Tech | MPC TSS | TEE (Enclaves) |
| Network | Distributed | Centralized (AWS) |
| Auth | Social Login | Passkeys / API |
| Cost | Affordable | Usage-based |
| Integration | SDK | API |
Scaling Considerations
Web3Auth's MPC-based architecture distributes key shares across multiple parties, which some teams prefer over Turnkey's centralized TEE model for philosophical or compliance reasons. The trade-off is signing latency—MPC ceremonies add overhead compared to TEE-based signing. Web3Auth is widely adopted with a large developer community, and at $69/month it remains the most affordable option in the space.
Why developers choose Web3Auth
Teams choose Web3Auth for robust social login support at the lowest cost in the market, combined with an MPC security model that offers decentralization benefits. It's a strong fit for consumer applications where social login is the primary requirement. However, Web3Auth does not include blockchain infrastructure like paymasters for gasless transactions, and its MPC signing latency (~500ms+) is significantly slower than Turnkey's TEE-based approach.
5. Dfns
Dfns is a direct competitor to Turnkey in the "Wallet-as-a-Service" infrastructure space. Dfns uses MPC and focuses heavily on security and compliance for banks and fintechs.
Comparison Table: Dfns vs. Turnkey
| Feature | Dfns | Turnkey |
|---|---|---|
| Tech | MPC | TEE |
| Target | Banks / Fintech | Crypto Native |
| Compliance | ✅ High (SOC2, etc) | ✅ High |
| Deployment | Cloud / On-prem | Cloud |
| Pricing | Enterprise | Usage |
Scaling Considerations
Dfns targets a different segment than Turnkey. Where Turnkey appeals to crypto-native builders, Dfns focuses on traditional financial institutions that require specific MPC guarantees, SOC2 compliance, and on-premises deployment options. Dfns typically has higher minimum monthly fees suited for enterprise contracts, which makes it less accessible for startups.
Why developers choose Dfns
Teams choose Dfns when they're building for regulated financial institutions that require MPC-based key management with compliance certifications and on-premises deployment options. Dfns and Turnkey are both infrastructure-level solutions, but Dfns' compliance focus gives it an edge with banks and fintechs. Neither Dfns nor Turnkey includes gasless transaction infrastructure like paymasters—both expect you to build that layer yourself.
Building In-House Wallet Product
Using Turnkey is essentially building in-house, just outsourcing the HSM/Enclave part.
Pros
- Control: You build the exact logic you want.
- Security: Turnkey handles the hardest part (key storage).
Cons
- Effort: You still have to build 80% of the wallet (transaction construction, parsing, gas, nonce management).

Conclusion
Turnkey is an incredible piece of infrastructure for teams that want maximum control and are prepared to build the entire wallet experience from the ground up. Its TEE-based signing is the fastest in the market, and its policy engine is well-suited for advanced use cases like AI agents.
However, if you want a complete wallet-as-a-service stack that gets you to market fast—with native smart accounts, built-in paymasters for gasless transactions, both embedded wallets and TEE backend wallets, and open-source flexibility through Opensigner—Openfort is the better choice. You get fair, usage-based pricing where you only pay per operation, without having to stitch together multiple vendors for the features that Openfort includes out of the box.
