  A tool to benchmark LLM APIs (OpenAI, Claude, local/self-hosted)2025 · llmapitest.com · ▲55

  I recently built a small open-source tool to benchmark different LLM API endpoints — including OpenAI, Claude, and self-hosted models (like llama.cpp). It runs a configurable number of test requests and reports two key metrics: • First-token latency (ms): How long it takes for the first token to appear • Output speed (tokens/sec): Overall output fluency Demo: https://llmapitest.com/ Code: https://github.com/qjr87/llm-api-test The goal is to provide a simple, visual, and reproducible way to evaluate performance across different LLM providers, including…

  Launch a private Ethereum Testnet with all clients and MEV infra2023 · github.com · ▲18

  We've been working with the Ethereum Foundation & Flashbots to build tooling and infrastructure for developers to test various workflows for Ethereum. As part of that work, anyone can now spin up a local Ethereum dev net with the entire Flashbots mev-boost infra (relayer, builder, boost) using the ethereum-package. This package supports all EL and CL client types, works on Kubernetes for scale testing, and comes with a few bells and whistles like metrics, mock-builders, and beacon chain explorers. This is the de-facto tool for teams modifying and testing the consensus layer. Here's a full…

  Chainstack Self-Hosted, hosting your own blockchain nodes made simpleJun 2026 · docs.chainstack.com · ▲9

  Hi HN, Alexey from Chainstack here. We built Chainstack Self-Hosted to package everything we’ve learned from 8+ years of running blockchain nodes into a single control panel. The goal we’re building this product around is to make blockchain infrastructure boring to operate. The software is free to install. You only pay for the infrastructure you run it on. The quickest way to get hands-on with it is through the Vultr Marketplace or one of the other providers listed in the docs. The current release supports Ethereum Mainnet, Sepolia, and Hoodi with Reth + Prysm full nodes. We’ll be adding…
