Jupiter alternatives

Jupiter is a Solana DEX aggregator that routes swaps across most major venues on the network, exposing a public quote endpoint at `lite-api.jup.ag/swap/v1/quote`. Quote latency sits on the hot path of every swap a wallet, trading UI or routing front-end builds: a 600 ms response pushes a perceptible delay onto the user, while an 80 ms response feels instant. This benchmark measures the wall-clock round-trip latency of Solana DEX aggregator quote APIs every 60 seconds from three Railway regions (us-east, eu-west, sgp), against tokens that are actually trending on Solana rather than the canonical SOL to USDC pair that every provider's edge cache already memorises. The harness maintains a 30-minute sliding window of bonded tokens from Mobula Pulse V2's WebSocket feed (post-bonding-curve graduates from Pump.fun, Meteora, Raydium LaunchLab and friends), picks one at random each tick and sends an identical 100 USDC to tokenOut quote request at 1 percent slippage to each provider in parallel. The HTTP client reuses TCP and TLS connections across ticks so the recorded latency reflects steady-state cost, not a cold-start handshake. Liquidity-gap failures (a provider that cannot route the picked token) land on a separate `solana_quote_no_route_total` counter and are excluded from the latency histogram, so a provider that fails fast on long-tail coverage is not penalised on the percentiles. Histogram buckets cover 10 ms to 5 s. Providers measured alongside Jupiter are Mobula, OpenOcean and Raydium; per-region tabs at the top of the page surface where each provider's infrastructure actually sits.
