Jupiter's router, opened up. Pick a pair and a size; the lab asks for the route it would take this second and draws every pool, split and hop.
Simulated against the chain first. Signed only by you, in Phantom. No fee from the lab.

Size ladder
The same pair at a tenth, the same, ten times and a hundred times your size. Grey fills with price impact.
Lab log
Swaps executed through SWAPLAB, read back from the chain after they land.
Method
Routes. Every quote is Jupiter's own answer from its keyless API at the slot it reports. The map draws its route plan as returned: each leg is a pool, the line weight is that leg's share of the trade.
Experiments. The same trade asked three ways: Jupiter's best route, the best single pool (direct routes only) and the best route with its biggest venue removed. Probes run one at a time; if Jupiter refuses one for rate limits, the lab says so instead of filling it in.
Prices. Dollar values use DexScreener's price for each token. "Cost" is what goes in minus what comes out at those prices: pool fees plus price impact.
Execution. Jupiter builds the transaction for your wallet, the lab simulates it on a public RPC, and only then Phantom asks you to sign. SWAPLAB holds no keys and takes no fee. A swap enters the log only after the chain confirms it.
