Built for remote workers, gamers, IT support, and anyone who just needs to know if their hardware works โ without installing anything.
LinearB TestHub360LinearB is recommended for software development teams, engineering managers, and project managers who want to improve visibility into their development processes, reduce cycle times, and boost overall productivity. It's particularly useful for teams that rely on agile methodologies and need to continuously monitor and improve their workflow efficiency.
TestHub360's answer:
TestHub360 is a free, browser-based device testing suite that runs entirely client-side โ your mic, camera, and keystroke data never leaves your browser. Unlike competitors that show ads inside tools, require downloads, or collect user data, TestHub360 is 100% private and works instantly in any modern browser with zero setup.
TestHub360's answer:
Competitors like OnlineMicTest or KeyTest offer one or two tools with ads and data collection. TestHub360 bundles 8 tools (mic, keyboard, webcam, speakers, mouse, CPS, dead pixel, screen recorder) into one site โ all free, all ad-free, all private. No account needed. No downloads. Just open a page and test.
TestHub360's answer:
Remote workers who need to verify their mic and webcam before a Zoom call. Gamers testing keyboard NKRO, mouse buttons, and click speed. IT support staff diagnosing hardware issues for colleagues. Content creators verifying audio and video gear before recording. Anyone who needs a quick answer about whether their hardware works.
TestHub360's answer:
Every time I joined a video call, I'd scramble to check if my mic and webcam were working. Existing testing sites either required downloads, pushed ads inside the tools, or collected data. I wanted something that just works โ open a page, run a test, get an answer. Eight tools later, it became the device testing hub I wished existed.

LinearB is an engineering productivity platform that provides visibility into developer workflows, automation, and process metrics. It collects data across the entire development lifecycle to diagnose blockers and optimize delivery. One user reports saving 321 developer-hours per month. - Source: dev.to / 3 months ago
Most tools measure half the picture. Traditional metrics platforms like LinearB focus on quantitative signals (DORA metrics, cycle time). Survey platforms like Culture Amp capture sentiment across organizations but aren't developer-specific. DX (founded by DORA/SPACE research creators) combines developer surveys with SDLC analytics. These approaches require deliberate implementation and buy-in. - Source: dev.to / 8 months ago
LinearB is a SaaS solution that retrieves metrics overtime, some of them being used to calculate DORA Metrics. They also have a Youtube channel that advocate for DORA Metrics and more. - Source: dev.to / over 2 years ago
In helping engineering orgs get visibility into developer workflows with LinearB, Dan Lines and Ori Keren discovered that the majority of cycle time was being spent in pull request and code review. They found that:. - Source: dev.to / about 3 years ago
