Things that do the arithmetic for you

All free, none behind an account. Several of them are useful whether or not you ever buy anything from us, which is deliberate: the calculations are the same whoever you get your feed from.

Calculate shred-feed bandwidthConvert packet rate and packet size into bits per second, packets per month, and 30-day storage with every unit shown.

Calculate a UDP receive bufferTurn packet rate, packet size, burst multiplier, and receiver stall tolerance into a transparent SO_RCVBUF request.

Calculate the cost of self-hosting shred deliveryAdd transit, ingest infrastructure, servers, engineering, operations, and failure exposure on the same 30-day basis as a feed subscription.

Test a UDP endpoint before buyingSend real UDP probes from 64.130.40.90 to a named IP and port, then verify arrival without an account or payment.

Visualise a Solana FEC setMap received data and coding shreds into one recovery set, show missing indexes, and calculate whether reconstruction is possible.

Generate a shred-feed firewall ruleGenerate inbound UDP rules for iptables, nftables, ufw, AWS security groups, and GCP from source IP 64.130.40.90.

Generate Linux UDP receiver tuningTurn a measured packet rate and stall target into reviewable Linux sysctl, socket, NIC, and queue recommendations.

Plan a shred-to-land latency budgetAdd detection, decode, decision, signing, submission, and landing ranges, then calculate slack against an opportunity deadline.

Estimate UDP packet loss and FEC exposureCalculate observed shred gaps, sampling uncertainty, transaction exposure, and idealized FEC recovery from explicit assumptions.

Compare shred-feed prices on one basisNormalize provider quotes by destination, 30-day term, included traffic, setup charges, and required infrastructure before comparing totals.

Decode a Solana shredInspect one Solana shred as bytes, header fields, signed material, payload, and FEC context without pretending one fragment is a transaction.

Convert a Solana slot to estimated timeEstimate time from a known slot anchor and measured slot interval, with an uncertainty band instead of a false exact timestamp.
