Ankr's Premium Tier excels at providing enterprise-grade reliability and performance for production applications. It guarantees a 99.9% SLA with dedicated endpoints, advanced rate limits, and priority routing to the fastest nodes. This tier is engineered for protocols requiring consistent sub-second latency and high throughput, such as DeFi frontends processing real-time price feeds or NFT marketplaces handling high-volume mint events. The infrastructure is backed by global load balancing and automatic failover, minimizing downtime risk.
Ankr's Premium Tier vs Free Tier
Introduction: The RPC Reliability Spectrum
A data-driven comparison of Ankr's Premium and Free RPC tiers, framing the choice as a fundamental trade-off between reliability and cost.
Ankr's Free Tier takes a different approach by offering a shared, community-accessible endpoint. This results in a cost-free service but introduces variable performance trade-offs. Users share bandwidth and node resources, which can lead to higher latency during network congestion and standard rate limits. It's a practical solution for prototyping, personal projects, or low-traffic dApps where budget constraints are paramount and occasional latency spikes are acceptable.
The key trade-off: If your priority is guaranteed uptime, predictable performance, and scalability for a mainnet application, choose the Premium Tier. If you prioritize zero-cost development, testing, and deployment for non-critical services, the Free Tier is a valid starting point. For CTOs managing a live protocol with significant TVL or user base, the Premium Tier's SLA and dedicated resources are non-negotiable for maintaining user trust and operational integrity.
TL;DR: Key Differentiators at a Glance
A data-driven breakdown for engineering leaders deciding between Ankr's service tiers. Focus on performance SLAs, reliability, and cost structure.
Premium: Guaranteed Performance
99.99% SLA with financial penalties for downtime, backed by dedicated infrastructure. This matters for production dApps, DeFi protocols, and NFT marketplaces where every second of downtime costs real revenue. Premium nodes are isolated from the public pool.
Premium: Priority & Rate Limits
No rate limits and prioritized request queues ensure consistent performance during network congestion (e.g., NFT mints, token launches). This matters for high-frequency trading bots, enterprise data indexing, and real-time analytics that cannot afford throttling.
Free: Zero-Cost Entry
No credit card required with a generous daily request allowance (approx. 50,000 RPC calls). This matters for prototyping, hackathons, personal projects, and low-traffic MVP testing where budget is the primary constraint.
Free: Shared Pool Constraints
Shared infrastructure with rate limits and lower priority during peak loads. This matters if your application experiences sporadic timeouts or slower block times during events like major airdrops or market volatility on Ethereum or BNB Chain.

Ankr Free Tier: Pros and Cons
A data-driven breakdown of Ankr's service tiers, highlighting key trade-offs in performance, reliability, and cost for CTOs and architects.
Premium Tier: Unmatched Reliability
Guaranteed 99.9% SLA: Premium endpoints come with a formal Service Level Agreement for uptime and performance. This matters for production dApps and high-frequency trading bots where downtime directly impacts revenue and user trust. Includes priority routing and advanced failover mechanisms.
Premium Tier: High-Performance Requests
No rate limits & 4x higher throughput: Handles up to 250 requests per second (RPS) compared to the Free Tier's 60 RPS. This is critical for data-intensive applications like NFT marketplaces indexing entire collections or DeFi dashboards aggregating real-time portfolio data across multiple chains.
Free Tier: Zero-Cost Entry
No credit card required: Provides immediate, free access to JSON-RPC endpoints for over 40 chains, including Ethereum, Polygon, and Avalanche. This is ideal for prototyping, hackathon projects, and early-stage development where budget constraints are paramount.
Free Tier: Rate-Limited & Shared Infrastructure
Strict 60 RPS limit & shared node resources: Performance can be inconsistent during network congestion as you share nodes with other free users. This is a significant constraint for scaling applications or any service requiring predictable sub-second response times, leading to potential request throttling.
Ankr Premium Tier: Pros and Cons
A data-driven breakdown of Ankr's Premium RPC service versus its Free Tier, focusing on performance, reliability, and cost trade-offs for production workloads.
Premium Pro: Guaranteed Performance & Uptime
SLA-backed reliability: Premium offers a 99.9% uptime SLA with financial penalties for non-compliance, versus no guarantees on the Free Tier. This is critical for high-frequency trading bots, DeFi protocols, and NFT marketplaces where downtime directly equals lost revenue. Premium nodes are isolated from public traffic, ensuring consistent sub-200ms response times.
Free Tier Con: Rate Limits & Shared Resources
Strict request throttling: Free Tier is limited to ~100-150 requests per second (RPS) and subject to daily caps, causing throttling errors during traffic spikes. Nodes are shared among all free users, leading to unpredictable latency. This makes it unsuitable for public-facing dApps, high-TPS games, or any service with variable load. A sudden surge in user activity can trigger rate limit errors (429), breaking the user experience.
When to Choose Free vs. Premium
Free Tier for Developers
Verdict: Ideal for prototyping, testing, and low-traffic dApps. Strengths: Zero-cost access to public RPC endpoints for major chains (Ethereum, Polygon, BNB Chain). Perfect for CI/CD pipelines, running automated tests, and building proof-of-concepts without budget constraints. Supports standard JSON-RPC calls for core development. Limitations: Shared public endpoints with rate limits (e.g., 1-5 requests per second). No guaranteed uptime SLA, higher latency during peak loads, and no advanced APIs. Not suitable for production traffic or mission-critical operations.
Premium Tier for Developers
Verdict: Essential for production applications, high-performance bots, and reliable infrastructure. Strengths: Dedicated RPC endpoints with high rate limits (e.g., 1000+ RPS), 99.9% SLA, and priority routing for lower latency. Access to advanced APIs like eth_getLogs with historical data, debug/trace APIs, and WebSocket subscriptions. Includes features like automatic failover and load balancing. Key Differentiator: Enables building scalable dApps on protocols like Uniswap, Aave, and Compound that require real-time, reliable blockchain data.
Final Verdict and Decision Framework
Choosing between Ankr's Premium and Free Tier is a classic trade-off between cost and performance, dictated by your application's scale and reliability requirements.
Ankr's Premium Tier excels at providing enterprise-grade reliability and performance because it leverages dedicated, load-balanced RPC endpoints with advanced features. For example, Premium users benefit from a 99.9% SLA-backed uptime, priority request routing that bypasses public rate-limiting queues, and WebSocket support for real-time applications like trading bots or NFT minting monitors. This tier is built for protocols like Aave or Uniswap that require consistent sub-second latency and cannot afford dropped transactions during peak network congestion.
Ankr's Free Tier takes a different approach by providing a shared, rate-limited gateway to blockchain data. This results in a cost-effective entry point for prototyping and low-volume dApps, but introduces the trade-off of potential throttling (typically 1-5 requests per second limits) and higher latency during network spikes. It's ideal for developers building a portfolio project, conducting initial R&D on a new chain like Berachain, or running a low-traffic community dashboard that doesn't require real-time data.
The key trade-off is between predictable cost and predictable performance. If your priority is unwavering reliability, high throughput (>1000 requests/minute), and advanced features for a production application with significant TVL or user base, the Premium Tier is a non-negotiable operational expense. If you prioritize minimizing initial infrastructure cost and can tolerate variable latency for development, testing, or very low-scale projects, the Free Tier provides substantial value. Consider a hybrid approach: use Free for development/staging environments and Premium for production to optimize both cost and reliability.
