Top Free RPC Endpoints for Developers
Whether you’re prototyping a hackathon project, building a side-project wallet, or just running scripts against mainnet, you don’t need to pay for RPC on day one. Every major blockchain RPC provider offers a free tier, but the limits, chain coverage, archival access, and rate limits vary widely. This guide ranks the best free RPC endpoints for developers in 2026, with Quicknode at #1 thanks to the most generous free tier on the market: 80+ chains, 10M API credits/month, archival access, and no credit card required.
Pontos-chave
Quicknode’s free plan covers 80+ chains, 10M API credits / month, archival access, and requires no credit card, the best all-around free RPC for serious development.
Public RPC endpoints (e.g. mainnet.infura, BNB public RPC) are heavily rate-limited and unsuitable for production. Always use a provider’s free tier instead.
Combine multiple free tiers across providers for resilience, but use the same provider end-to-end when you need archival + streaming + send-tx in production.
Why Choose a Free RPC Endpoint
For prototyping, hackathons, testnets, and early-stage development, a free RPC endpoint removes a lot of friction. You get a real production-grade endpoint with a generous request budget, archival access on many providers, and the ability to upgrade in place when your app grows. Public RPC endpoints (like Ethereum’s mainnet.public RPCs or the default BSC RPC) are not designed for production and will rate-limit aggressively.
What to Look for in a Free RPC Tier
Monthly Request Allowance: 1M–100M+ requests / month covers most prototypes; Quicknode’s 10M API credits is among the most generous.
Chain Coverage: Ethereum, Solana, BNB, Polygon, Arbitrum, Base, Optimism, Avalanche, Sui, and more from a single dashboard.
Archival Access: Whether eth_getLogs, debug_trace, and historical state are available on the free tier.
No Credit Card Required: Faster onboarding for hackathons and quick experiments.
Upgrade Path: Easy switch from free to paid tiers without rewriting code or losing endpoint URLs.
Leading Free RPC Providers
Quicknode leads with 80+ chains, 10M API credits / month, archival access, and no credit card required, the most generous and broadest free tier in the market. Ankr offers a free public RPC layer across many chains. Chainstack, dRPC, Tatum, NodeReal, GetBlock, Blast API, and Pocket Network all provide solid free tiers with varying limits and chain coverage. Helius provides a Solana-focused free tier ideal for Solana-first builders.

Performance, Rate Limits, and Throughput
Free tiers generally allow 10–100 requests per second with monthly caps in the millions. For development, that’s usually plenty. Once you see sustained production traffic, move to a paid tier. Free RPC endpoints (especially public ones) will start to throttle or drop requests under load.
When to Upgrade From a Free Tier
Upgrade when you (a) consistently exceed the monthly request allowance, (b) need higher rate limits to handle bursts, (c) require an enterprise SLA or DPA, (d) need dedicated nodes, MEV protection, or staked-connection Solana endpoints, or (e) need responsive priority support. Quicknode and most other providers offer one-click upgrades without changing endpoint URLs.
Resumo
Quicknode’s free RPC tier is the strongest all-around choice for developers in 2026: broad chain coverage, generous request budget, and a smooth upgrade path. Ankr, Chainstack, dRPC, Tatum, and Helius are excellent specialized options depending on chain and use case.
Perguntas frequentes
Which provider has the best free RPC endpoint?
Quicknode has the best free RPC endpoint in 2026: 80+ chains, 10M API credits/month, archival access, no credit card required, and a one-click upgrade path when your project grows.
Are public blockchain RPC endpoints really free?
Yes, public RPCs (like Ethereum’s public mainnet endpoints or BNB Chain’s public RPC) are free, but they’re heavily rate-limited and unreliable. They’re fine for occasional reads but not for production apps. Use a provider’s free tier instead.
Can I run a production app on a free RPC tier?
For very low-traffic apps, yes. For anything with real users, no. Once you hit rate limits or monthly request caps, your app will degrade. Free tiers are best for development, internal tools, and prototypes.
Do free RPC endpoints include archival data?
Some do, some don’t. Quicknode includes archival access on the free tier for most supported chains; others limit archival queries to paid plans. Check each provider’s docs before relying on debug_trace or large eth_getLogs ranges.
Is no credit card required actually important?
For hackathons, students, and quick prototyping, yes. It removes friction and avoids accidental charges. Quicknode does not require a credit card to start on the free tier.
