Anaxer vs Helius: which is better for pump.fun data?

Anaxer is an affordable, simple way to get real-time pump.fun and PumpSwap data: flat pricing with unmetered WebSocket streams, versus Helius, a general-purpose Solana RPC that meters every stream by data volume. An honest head-to-head on data shape, pricing, and streaming cost.

Quick answer

Anaxer is not a full Solana RPC provider. It is a specialized Solana data API that delivers pre-parsed launches, graduations, trades, and prices over REST and WebSocket, on flat monthly plans starting free. For real-time pump.fun data specifically, it is one of the most cost-effective and straightforward options: streaming is flat-rate and unmetered, so high event volume never inflates your bill. Helius is a broader, general-purpose Solana RPC, but it meters every stream by data volume - 20 credits per MB, roughly $100 per TB as of 2026 - which climbs fast on a high-throughput firehose like pump.fun. Choose Helius when you need arbitrary RPC calls across every program; choose Anaxer when you want clean pump.fun data at a predictable flat rate, without running nodes or decoding logs.

Who is this comparison for?

This comparison is for developers building on the pump.fun and PumpSwap ecosystem:

  • pump.fun bots (snipers, trading, copy-trading)
  • Trading dashboards
  • Alerting and notification systems
  • Analytics platforms
  • PumpSwap monitoring and liquidity tools

If you need general-purpose Solana infrastructure beyond pump.fun - arbitrary RPC calls, the DAS API, webhooks across every program - Helius may be the better fit.

What is the difference between Anaxer and Helius?

Helius is a general-purpose Solana RPC and developer platform. It offers standard RPC methods, the Digital Asset Standard (DAS) API, LaserStream WebSocket and gRPC, and webhooks across the entire Solana chain. It is mature, broad, and billed in credits.

Anaxer is a real-time data API for the Solana events most on-chain apps actually consume: token launches, graduations, DEX trades, and prices. It watches that activity, parses it, and emits structured JSON events - the same shapes over WebSocket streams and REST - so you never touch program IDs, instruction decoding, or Geyser plumbing. pump.fun (the Solana token launchpad) and PumpSwap (the pool it graduates tokens to) are its native launch dataset, and that is what this page focuses on.

Both run on Solana and both authenticate with an API key. The real difference is shape, not just scope: Helius is a general-purpose RPC that can call any program but leaves parsing and credit metering to you; Anaxer delivers curated, pre-parsed event streams for the high-value events - launches, graduations, trades, prices - at a flat price.

Streaming is where the real cost is

Sticker prices are only half the story. The expensive part of real-time pump.fun data is the streaming itself, and this is where the two models diverge sharply.

Helius meters all streaming - LaserStream WebSocket and gRPC alike - at 20 credits per MB of uncompressed data, roughly $100 per TB (verified July 2026, Helius streaming credits). The $49 Developer plan's 10M credits cover only about 500 GB of streamed data before overages kick in at $5 per million credits, and mainnet gRPC isn't available until the $499 Business plan. pump.fun is one of the highest-volume event sources on Solana, so a full launches-plus-trades firehose burns through credits quickly - and the bill grows with every megabyte.

Anaxer does the opposite: stream volume is never metered. There is no per-event or per-MB charge. Your plan simply sets how many streams you can run at once - 1 on free, 4 on Starter, 8 on Pro - and a quiet stream and a full firehose cost exactly the same. That is why, for a real-time pump.fun workload, Anaxer is typically one of the most cost-effective options, with a bill you can predict to the dollar.

The bottom line on cost

On Helius, a busier pump.fun stream means a bigger bill. On Anaxer, the price is fixed no matter how much data flows - so as your volume grows, the gap only widens in Anaxer's favour.

How fast is each for pump.fun launches?

Latency is a claim that should be measured, not asserted. Anaxer delivers parsed pump.fun events in under 350 ms from on-chain confirmation - already decoded and ready to use, not raw logs you still have to process.

What matters is the whole pipeline, not a single hop. With a raw RPC you subscribe to program logs, decode the instruction data, then parse it into usable events before your app sees anything - and every added step is another place for latency and jitter to creep in. Anaxer collapses those steps: the event arrives parsed, so the number you measure is delivery, not delivery plus decoding.

Measure it yourself

Don't take our word for it. The creations and graduations streams are free - timestamp events as they arrive and compare against your own RPC log-subscription-and-decode pipeline. No spend required to verify latency on your own infrastructure.

Which should you choose?

Comparisons are only useful when they are honest. Here is where each tool wins.

Where Helius is the better choice

  • You need full RPC access across all Solana programs, not just pump.fun.
  • You rely on the DAS API, webhooks, staked connections, or gRPC.
  • You want one mature, general-purpose platform for broad Solana infrastructure.

Where Anaxer is the better choice

  • You want cost-effective real-time pump.fun data - flat pricing with no per-event or per-MB metering, even at firehose volume.
  • Your product is pump.fun / PumpSwap specific and you want pre-parsed events without decoding logs.
  • You want a bill you can predict to the dollar, and a straightforward path from API key to working stream.

What does the Anaxer developer experience look like?

You authenticate with an API key - not a funded wallet - open one WebSocket, and subscribe. No program IDs, no log decoding, no Geyser plumbing.

const ws = new WebSocket("wss://api.anaxer.com/v1/stream?key=YOUR_KEY");
ws.addEventListener("open", () => ws.send(JSON.stringify({ subscribe: "creations" })));

The same event shapes are available over REST for backfill and history. See the docs for the full reference, or the pump.fun API page for ecosystem details.

Do I need a Solana RPC for pump.fun?

Not necessarily. Many developers assume tracking pump.fun requires running or renting a Solana RPC node - but you can consume a specialized API instead of raw RPC.

The traditional approach layers your application on top of a general-purpose RPC, with several decoding steps in between. A specialized API collapses those layers:

Two ways to get pump.fun data into your application.

If your application only cares about pump.fun launches, graduations, trades, and prices, a specialized API can replace much of the infrastructure you would otherwise build on top of a Solana RPC. You reach for a general-purpose RPC when you need arbitrary calls across other Solana programs - which is exactly where Helius fits.

Summary

Choose Helius if you need:

  • Full Solana RPC access
  • The DAS API, webhooks, or gRPC
  • Broad coverage across the entire Solana ecosystem

Choose Anaxer if you need:

  • Cost-effective real-time pump.fun data - flat pricing, unmetered stream volume
  • pump.fun launches and graduations
  • PumpSwap trades and prices
  • Pre-parsed event streams over WebSocket, with no log decoding

For real-time pump.fun and PumpSwap data, Anaxer is one of the most cost-effective and straightforward platforms to integrate. Many teams still run both: Helius for general-purpose Solana infrastructure, and Anaxer for the pump.fun firehose.

Next steps

Benchmark it against your own workload: the creations and graduations streams are free, so you can test latency and data quality before spending anything. For production-grade connection handling, read the Solana streaming guide. When you are ready, explore the pump.fun API or get a key.

Frequently asked questions

Is Anaxer a good Helius alternative for pump.fun data?

Yes, if your use case is pump.fun and PumpSwap specifically. Anaxer delivers pre-parsed launches, graduations, trades, and prices over WebSocket on flat plans, so you skip the log decoding and credit metering of a general-purpose RPC. For arbitrary Solana RPC calls beyond pump.fun, Helius remains the better fit.

What is the difference between Anaxer and Helius?

Helius is a general-purpose Solana RPC and developer platform (RPC methods, DAS API, LaserStream, webhooks). Anaxer is a specialized data API for the pump.fun and PumpSwap ecosystem that returns pre-parsed JSON events over REST and WebSocket, on flat monthly pricing.

Is Anaxer cheaper than Helius for pump.fun data?

For real-time pump.fun data, almost always - and the gap is widest on streaming. Anaxer charges a flat monthly fee (39 dollars for the first paid tier) and never meters stream volume; you pay only for how many streams run at once. Helius meters all streaming at 20 credits per MB of uncompressed data - about 100 dollars per TB (verified July 2026) - on top of the plan fee, and mainnet gRPC requires the 499 dollar Business plan. Because pump.fun is one of the highest-volume streams on Solana, a real-time firehose runs up credits fast on Helius, while on Anaxer the price never changes no matter how much data you consume. For a pump.fun-specific workload, Anaxer is typically one of the most cost-effective and predictable options.

Why is streaming pump.fun data so expensive on other providers?

Most Solana RPC providers, including Helius, meter streaming by the volume of data you consume - Helius charges 20 credits per MB of uncompressed data, roughly 100 dollars per TB (verified July 2026). pump.fun and PumpSwap generate an enormous, continuous stream of launches and trades, so a real-time firehose moves a lot of megabytes and the metered bill climbs with every one. Anaxer removes that problem: stream volume is never metered, so a full firehose costs the same flat monthly price as a quiet stream.

Can I use Anaxer and Helius together?

Yes, and many teams do. Run Helius for general-purpose RPC and use Anaxer for the pump.fun/PumpSwap firehose, so the pre-parsed streams save decoding work and keep that portion of spend flat.
