Fern vs QuickNode
Side-by-side comparison of AI visibility scores, market position, and capabilities
Automatic multi-language SDK and API documentation generator from OpenAPI specs; $13M Bessemer-led Series A from YC W23 serving Cohere and ElevenLabs competing with Stainless for API developer experience.
About
Fern is a New York-based API tooling company that automatically generates multi-language SDKs and API documentation from OpenAPI specifications — enabling API companies to publish high-quality client libraries in TypeScript, Python, Java, Go, Ruby, and C# from a single source of truth, eliminating the significant engineering effort of manually building and maintaining SDKs for each programming language a developer audience uses. Founded in 2022 by Danny Sheridan and Deep Singhvi and a Y Combinator Winter 2023 graduate, Fern raised $13 million total including a $9 million Series A led by Bessemer Venture Partners with 30 employees.
Blockchain RPC infrastructure provider for 30+ chains including Ethereum and Solana; managed node endpoints enabling Web3 developers without self-hosted node complexity competing with Alchemy.
About
QuickNode is a blockchain infrastructure provider offering high-performance RPC (Remote Procedure Call) node endpoints, APIs, and developer tools for Web3 applications — enabling blockchain developers to connect to Ethereum, Solana, Bitcoin, Polygon, Arbitrum, Base, and 30+ other blockchain networks without running their own nodes. Founded in 2017 by Auston Bunsen, Alex Nabutovsky, and Dmitry Shklovsky in Miami, QuickNode has raised approximately $60 million and serves as infrastructure backbone for thousands of Web3 applications, DeFi protocols, NFT platforms, and blockchain games.\n\nQuickNode's core service is managed blockchain nodes — instead of running a self-managed Ethereum or Solana node (which requires significant technical expertise and hardware), developers connect to QuickNode's globally distributed node infrastructure through a standard JSON-RPC endpoint. The service provides high availability, low-latency blockchain data access, websocket support for real-time event subscriptions, and enhanced APIs (like Icy Tools for NFT data, token transfer APIs) that simplify common Web3 development patterns. QuickNode's Marketplace offers third-party Web3 data add-ons (token prices, NFT metadata, identity data).\n\nIn 2025, QuickNode competes with Alchemy (the category leader) and Infura (Consensys) for blockchain RPC infrastructure market share. The Web3 developer infrastructure market contracted significantly from 2021-2022 NFT/crypto peaks, then rebounded with Ethereum's Dencun upgrade, Bitcoin ETF approvals, and renewed DeFi activity in 2024-2025. QuickNode's 2025 strategy emphasizes its multi-chain breadth (supporting more chains than competitors), its developer experience (QuickNode Streams for real-time blockchain data pipelines), and growing its enterprise customer segment for institutional blockchain applications.
