Helius review
A Solana-focused developer platform with RPC, streaming, transaction delivery, and data APIs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Helius provides cloud infrastructure and developer tools for building applications on Solana. Its offerings include shared and dedicated RPC nodes, transaction submission through Sender, streaming through LaserStream, webhooks, historical data retrieval, parsed transaction and event APIs, and digital asset and token APIs. The platform is aimed at teams that want managed access to Solana data and transaction infrastructure, including crypto startups, trading firms, and financial companies. It is available through web and API, with TypeScript, Rust, JavaScript, and Go listed as supported SDKs.
The published monthly plans scale capacity and streaming access. Free includes 1M credits per month, 10 requests per second, 1 sendTransaction per second, Standard LaserStream WSS, and community support. Developer costs $49 per month and raises those limits to 10M credits, 50 requests per second, and 5 sendTransaction per second; it adds Staked Connections, LaserStream WSS, and LaserStream gRPC on devnet. Business is $499 per month for 100M credits, 200 requests per second, 50 sendTransaction per second, and 5 sendBundle per second. Professional is $999 per month, with 200M credits, 500 requests per second, 100 sendTransaction per second, and 5 sendBundle per second. Both paid tiers include Staked Connections and LaserStream WSS and gRPC. Enterprise offers volume discounts, custom rate limits, advanced geographic coverage, and latency and uptime SLAs.
The product’s breadth is useful for teams that need more than basic node access: it combines data retrieval, real-time updates, transaction delivery, archival access, and validator infrastructure within a Solana-specific toolkit. That focus is also its main constraint. Teams building across multiple chains should look for a platform with broader chain support, while Solana teams can assess whether the free tier’s rate limits are sufficient before moving to a paid plan. Helius lists community, chat, and documentation support, and states SOC 2 compliance. Choose it when managed Solana infrastructure and data APIs are central to the project; skip it if multi-chain coverage is a requirement.
