No description of Mattermost yet.
Canmetry is a web workbench for offline CAN and CAN FD logs. Engineers drop in Vector BLF, ASAM MF4 or ASCII traces, bind one or more DBC files per channel, and read physical signals on a graph or raw frames in a trace view. The same site also converts BLF/MF4/ASC to CSV or MATLAB .mat, and can...

As answered by people managing Mattermost and Canmetry.
Canmetry's answer:
Canmetry opens recorded CAN and CAN FD logs in the browser. Drop in a BLF, MF4, ASC, CSV or candump file, map a DBC to each channel, and you get signal graphs, a frame trace and a DBC bit layout — no CANoe or CANalyzer install, and it runs on Windows, macOS and Linux.
Decoding for that local workflow happens in the browser; the log and DBC are not uploaded unless you later save a cloud project. The same site also converts BLF, MF4 and ASC to CSV or MATLAB .mat, and can view, check, compare or export a DBC.
It is not a live bus tool. There is no hardware capture, transmit, CAPL, ECU simulation or HIL.
Canmetry's answer:
Choose it when the job is to read a file you already have, not to replace a Vector bench.
Typical cases: a supplier sent a BLF and you have no Vector licence; you are on a Mac or Linux machine; you need DBC-decoded signals in MATLAB, Python or Excel. Local analysis does not require an account.
Vector CANoe and CANalyzer remain the right tools for live capture, transmit, simulation and automated test. BUSMASTER and SavvyCAN are desktop apps with hardware in the loop. Canmetry is the faster path for offline decode and export, with an explicit 150 MiB per-file limit on local analysis.
Canmetry's answer:
Automotive and embedded engineers who work with recorded bus logs: test, calibration, diagnostics, and supplier or OEM teams who receive BLF, MF4 or ASC files.
Also students and engineers who know CAN but do not have a Vector seat, and anyone who needs to open a CANoe-recorded BLF on macOS or Linux, or hand decoded signals to MATLAB.
They already know frames, DBC, factor/offset and Intel vs Motorola. They do not need a full test-automation suite for this task.
Canmetry's answer:
The product started from a narrow gap: opening a recorded CAN log should not depend on a Windows-only licensed install.
CANoe is built for analysis, simulation, stimulation, testing and diagnostics. A large share of day-to-day work is smaller than that — check whether an ID is on the bus, decode it with the matching DBC, plot a few signals, export CSV or MAT. Canmetry is that offline path in a browser, including Mac and Linux, plus converters and DBC tools on their own pages.
Live interfaces, CAPL and HIL stay in the tools already built for them.
Canmetry's answer:
TypeScript and React, with TanStack Start and Vite In-browser CAN / CAN FD and DBC parsing (candied for DBC; BLF, MF4 and ASC readers aligned with python-can layouts) Web Workers so decode does not freeze the page Cloudflare Workers for hosting Optional cloud projects after sign-in (auth and object storage); local open-and-decode does not use that path
