Solana gRPC + RPC, one endpoint key.
Yellowstone gRPC streams filtered and parsed at the source, plus flat-priced JSON-RPC bundled in on the same API key. One credential for reads, writes, and streams. No credit metering, dedicated sendTransaction bucket so heavy reads never starve submits.
Server-side filtering
Send us your SubscribeRequest, we only ship the matching traffic. Your bot never sees votes, failed txns, or programs it doesn't care about.
Pre-parsed JSON
We decode Borsh, resolve account indices, and convert lamports server-side for Pump.fun, Raydium, Jupiter, and common SPL flows. Zero parse cost on your side.
JSON-RPC bundled in
Every paid plan includes flat-priced JSON-RPC on the same API key. Read with rpc.subglow.io, stream with grpc.subglow.io:443. One credential, one bill, no credit math. Details →
Drop-in compatible with your stack
Subglow speaks standard Yellowstone (Dragon's Mouth) gRPC. Point any existing client at grpc.subglow.io:443 with your API key. No protocol lock-in.
Pre-parsed program presets
Point at a program, get structured events. No Borsh decode libraries, no IDL lookups, no account-index resolution. Ship your bot in the afternoon.
30–80ms p50 slot→client.
Wall-clock time from Solana slot confirmation to your gRPC client's Recv() callback. Measured over a 30-day rolling window, p99 ≈ 180ms. Full methodology, replication instructions, and head-to-head numbers against every major provider.

We also built a copy trader on our own gRPC.
Subglow Copy Trading runs on the exact infrastructure sold on this page — private Yellowstone, Jito bundles, 200–400ms end-to-end. If you don't want to build a bot yourself, mirror top KOLs non-custodially for a 0.2% flat fee.
FAQ
What makes Subglow's Solana gRPC different from raw Yellowstone?
Three things: (1) server-side filtering — we only ship the transactions your SubscribeRequest matches, so your bot never sees the firehose; (2) pre-parsed JSON — we decode Borsh and resolve account indices for Pump.fun, Raydium, and Jupiter server-side, eliminating the 15–30ms parse tax every client otherwise pays; (3) flat monthly pricing — Sniper $99/mo, Pro $249/mo, no credit metering. Wire protocol is 100% Yellowstone; your existing client code works unchanged.
Which programming languages do you support?
Every language with a gRPC client supports Subglow — because Subglow speaks the standard Yellowstone (Dragon's Mouth) protocol. We publish dedicated guides for Python (grpcio), TypeScript (@triton-one/yellowstone-grpc), Rust (yellowstone-grpc-client), and Go (grpc-go with generated stubs). Community libraries exist for Java, C#, and Elixir.
What's the end-to-end latency for a typical Pump.fun trade?
30–80ms p50 from Solana slot confirmation to your gRPC client's Recv() callback, measured over a 30-day rolling window from colocated Amsterdam/Frankfurt. p99 sits around 180ms. See /solana-grpc-latency-benchmark for the full methodology and comparison against Helius, QuickNode, Triton, Chainstack, and Shyft.
How many concurrent streams do I get on each plan?
Sniper ($99/mo) includes 2 concurrent gRPC streams on shared infrastructure with standard delivery and WebSocket fallback. Pro ($249/mo) includes 10 concurrent streams, zero rate limits, full-speed delivery, custom Program ID filters, shred-aware filtering, and priority support. Dedicated gives you unlimited streams on private infrastructure colocated in Frankfurt or NY4 with a 99.9% latency SLA.
Can I use Subglow for Jito bundle submission?
Yes. Subglow includes a Jito relay endpoint on every plan — submit signed bundles to grpc.subglow.io/jito with your API key, and we forward them to the Jito block engine with auto-tip bidding. Inclusion rates above 95% at tips above the current 40th-percentile. Most trading bots pair Subglow for gRPC reads with Subglow-routed Jito bundles for writes.
Is Subglow compatible with Helius Laserstream clients?
No — Laserstream is a proprietary Helius protocol. Subglow speaks standard Yellowstone, so if you're on Laserstream you'd rewrite your streaming client against the Yellowstone API. Most teams complete this migration in a few hours; your trading logic, downstream integrations, and transaction broadcasting code remain unchanged.
Is JSON-RPC included with gRPC?
Yes. Every paid plan bundles a flat-priced JSON-RPC endpoint on the same Subglow API key. Sniper gets 50k RPC + 2k sendTransaction per day, Pro gets 500k RPC + 20k sendTx, Dedicated is unlimited. Point your @solana/web3.js Connection at https://rpc.subglow.io/<apiKey> and it just works. sendTransaction has a dedicated bucket so heavy read traffic never starves your submits. See /solana-rpc for the full surface.
Do you offer a free trial?
Yes — apply for a free trial from the pricing page. Due to high demand we review applications manually to ensure quality of service (typically within 24 hours). Approved trials get 1 stream and 100 requests/day against the built-in Pump.fun/Raydium/Jupiter filters. If you want to skip the review, Sniper at $99/mo starts instantly.
