I built a browser plotter for CSV, CAN logs and audio files. Nothing gets uploaded.

As an automotive engineer, I got tired of writing throwaway Python scripts or opening a heavy desktop tool just to look at a few signals that explained an issue. It supports multiple formats like CSV, Excel, WAV/MP3 and CAN logs (TRC, BLF, ASC and Linux candump). The format is automatically detected. Basic processing and stats are available so you rarely need to go further. Everything runs in the browser and the file is never uploaded. Whatever you need in one visit

AI 分析

痛点:工程师(尤其汽车/嵌入式)只想快速看一眼信号波形,却被逼着写一次性 Python 脚本或启动笨重的桌面软件,且不希望把敏感数据上传到云端。

目标用户:汽车/嵌入式工程师、测试工程师、数据分析师,需要临时查看 CSV、CAN 日志(TRC/BLF/ASC/candump)、WAV/MP3 信号波形的人

证据:As an automotive engineer, I got tired of writing throwaway Python scripts or opening a heavy desktop tool just to look at a few signals that explained an issue. ... Whatever you need in one visit is free, with no sign-up. There's an optional one-time Pro upgrade ($9.99) so it remembers your setup between visits, adds more panels and includes a downloadable copy that runs fully offline.

变现:免费网页版引流 + $9.99 一次性买断 Pro(记忆配置、更多面板、可离线运行的下载版);后续可做团队/企业授权、批量处理、自定义解析格式、CLI 与 CI 集成

MVP:用 React + uPlot 做一个纯前端本地解析器:拖拽 CSV/CAN 日志/音频 → 自动识别格式 → 多面板同步缩放与基本统计(min/max/均值/FFT 频谱),全部 FileReader/WebWorker 本地处理不上传;先只支持 CSV + candump + WAV,配一个 $9.99 一次性 license(Lemon Squeezy/Gumroad)解锁配置持久化与离线包

竞品:Vector CANalyzer / CANoe、SavvyCAN、PEAK PCAN-View、Wireshark、Plotly/Dash 自建脚本、Excel / MATLAB、各类在线 CSV plotter

摘要:一名汽车工程师发布浏览器端本地信号绘图工具,支持 CSV、Excel、WAV/MP3 与 CAN 日志(TRC/BLF/ASC/candump)自动格式识别,文件不上传、无需注册。基础功能免费,另有 $9.99 一次性 Pro 升级(记忆配置、更多面板、可离线下载版)。痛点真实且垂直(避免写一次性脚本和笨重桌面工具),纯前端单人可实现,但尚未看到实际购买或他人付费意愿的证据。
