The quick performance score for ESP boards.
Flash, run, score and compare your ESP8266 or ESP32-family board in a clean leaderboard built for real maker projects.
About Espmark
Espmark is a browser-friendly benchmark for ESP boards. It turns a short firmware run into one readable score plus CPU, memory, flash and practical IoT breakdowns.
The goal is simple: help ESP builders compare boards before choosing one for sensors, displays, gateways, automation and other everyday embedded projects.
Benchmark
The test mixes integer and float compute, RAM and heap work, flash reads, JSON, strings, CRC32 and SHA-256. The server normalizes the raw timings into scores where higher is easier to compare.
Raw timings are still shown for people who want the details, but the headline score is what you use for quick board-to-board comparison.
Connect over USB and flash the matching generic Espmark firmware in the browser.
Pick the serial port and keep the board attached after it reboots.
Start the benchmark and wait until the board prints a complete result.
Choose the exact board, pass the check and publish to the leaderboard.
Firmware Flash
The installer detects the ESP chip family and flashes the matching generic Espmark build.
Benchmark Control
Connect the board, start the run and let the page capture the result automatically.
After flashing, reconnect the serial port if the board rebooted.
Chrome or Edge over HTTPS is required for USB serial access.
