Alchemy vs thirdweb
Side-by-side comparison of features, pricing, ratings, and alternatives.
Alchemy is a web3 infrastructure platform that gives developers reliable node RPC access, data APIs, and smart wallet tooling for building blockchain applications. It supports Ethereum and 50+ other networks including Polygon, Arbitrum, Optimism, Base, and Solana, and is used by companies like Visa, Circle, Stripe, and OpenSea.
thirdweb is a development platform for building Web3 applications, giving developers pre-built infrastructure for smart contracts (ERC20, ERC721, ERC1155), wallets, and cross-chain token bridging and swaps. It targets teams building token economies, DeFi apps, games, and consumer apps that need blockchain functionality without building infrastructure from scratch. More recently thirdweb has expanded into infrastructure for AI agents that transact autonomously, offering wallet solutions for agents, native payment support for HTTP and agentic payments in any token, and real-time blockchain data access. Its SDKs and audited smart contracts are usable by hobbyist developers on lower tiers up through enterprise organizations on custom plans.
- Generous free tier (30M compute units/month) usable for real testing and small apps
- Broad multi-chain coverage across 50+ networks from one API
- Used in production by major fintechs like Visa, Circle, and Stripe
- Usage-based pricing scales cost with actual API consumption
- Broad toolkit covers contracts, wallets, and payments in one platform
- Managed infrastructure reduces need for separate RPC/IPFS providers
- Clear tiered pricing published on the site
- Early mover into AI-agent payment infrastructure
- Compute-unit-based billing can be confusing to estimate costs upfront
- Advanced features like custom rollup infrastructure are aimed at larger teams, not hobbyists
- Enterprise-grade throughput and SLAs require custom/contact-sales pricing
- Entry-level paid tier starts at $99/month, a real cost for early-stage teams
- Requires blockchain development knowledge to use effectively
- Advanced support and custom infrastructure are locked behind higher tiers
