Pump Portal alternatives

Pump Portal is a single-purpose WebSocket on Solana, scoped to pump.fun and the bonding-curve launchpad ecosystem around it (new token creations, migration to Raydium, per-mint trade events). The surface is intentionally narrow: no support for other chains, no general DEX coverage outside the pump.fun graduates and no historical query layer beyond the live stream. The free tier exists, but high-volume readers route through a paid trading endpoint that adds a per-trade priority fee on top. The provider sits close to the launchpad it tracks rather than near a canonical Solana archive, so the bottleneck is usually the upstream indexer rather than the WebSocket itself. Teams that outgrow the pump.fun-only scope (cross-DEX routing, non-Solana chains, OHLCV history) tend to drop it the moment a second venue or chain enters the product.
