Pricing

One file — complete and free.

Open a file from any instrument, view it, measure it, fix it and save it as .sor — no sign-up.

There is no paid tier yet: it will be about the conveniences of volume, and we will name the price when it ships — not before.

FOREVER

View and edit

Free

One file, complete. No sign-up

  • Open a file from any instrument: both .sor generations, .msor, three .trc dialects (EXFO, Anritsu T5 and T6), Yokogawa, INNO, .bdr, .csor, .tst, .TFW
  • A workspace of 3 files — view and switch; a fourth loads as soon as one of the three is closed
  • Automatic event detection, and span measurement with A/B cursors by two methods
  • Edit metadata, events and the curve
  • Overlay open files on one chart — by link, no install, on any OS
  • Checks against the thresholds you set

IN PREPARATION

Volume conveniences

No price yet

For people with many files

What becomes paid is the volume of work — not viewing and not editing. We will name the contents and the price when the tier is ready: we don't want to promise what isn't built. What the product can do today is honestly split out on the home page, under "What works today, and what we're still writing".

Your projects remain yours. If a subscription ever ends, everything you created can still be opened, read and exported — the paid tier does not lock your files in.

Want a say in what this becomes

We are looking for installers, crew leads and the people who accept measurement packages — for a twenty-minute conversation. Not a demo and not a sales call: we want to know how your handover actually works.
