Why Kalyvor
Built for people who value their time
Every data tool is fast, private and genuinely free — no dark patterns, no surprises.
Fast cloud processing
Jobs run on dedicated workers and finish in seconds — no queue, no spinner you can go make coffee to.
Auto file deletion
Everything you upload is erased the moment the job finishes. Nothing is written to long-term storage, so there is no retention period to wait out.
Works everywhere
Desktop, tablet or phone, any modern browser. Nothing to install, no plugins, no extensions.
Batch processing
Drop in a folder's worth of files and run the whole set through one tool in a single pass.
Privacy first
Encrypted in transit, never used to train models, never sold. Many tools never send the file at all.
No installation
Open a tab and go. No account needed to start, no download, no licence key to hunt for.
How it works
XML Validator in three steps
No account, no installation, no manual. It takes about as long to do as it does to read.
- 01
Paste your XML
Paste a document directly, or upload a file. Nothing is uploaded to a server.
- 02
Read the report
Well-formed or not, see it at a glance — and for well-formed XML, its root element, size and shape: elements, attributes and maximum nesting depth.
- 03
Copy or fix
Copy the report, or jump straight to the line and column of the first problem if there is one.
