Check whether your hardware is still supported by the vendor
Search one part number or check a whole estate. You get the manufacturer's published dates, the bulletin they came from, and the date it was last checked.

Evidence
Vendor-published
1,442 products are already past support.
A further 106 lose support within twelve months, and 75 carry different dates for different part numbers inside the same family, which is why a family name alone is not a safe answer.
Every date is traceable to a bulletin.
93.7 percent of the dates on this site are read directly from the manufacturer's own end-of-life notice, and every one of those links back to it. The remaining 6.3 percent are derived from a published support-life policy and say so on the page.
Part numbers are tracked individually, so a family that retired in stages does not hide the SKU you actually own.

Unsupported and actively exploited
59 tracked products are past their manufacturer's last date of support and carry a vulnerability CISA lists as actively exploited. Past end of support on its own is a planning note; both at once is an audit finding.

Three ways to use EOSL.ai
Verify a part
Search a SKU, model or family for its dates, the source bulletin, the verification date and every related part number.
Assess an inventory
Paste part numbers or drop a CSV into the bulk checker. It runs in the browser, the list never leaves the machine, and there is no account.
Monitor over time
Hold owners, exceptions and replacement targets against the estate in Stack Monitor, and re-check when the vendor data moves.

Why trust these dates
Linked to the source
Every end-of-sale and EOSL date links to the vendor end-of-life bulletin it came from. Click through and confirm it yourself.
Down to the part number
Look up a specific SKU, not just a product line, and get its exact support status, milestone dates and last security firmware.
Dated and re-checked
Every record shows when it was last verified against the source, and the catalogue is re-swept each week.
Conflicts shown, not hidden
When two bulletins disagree on a date, EOSL.ai surfaces both instead of silently picking one.
Software end of life
EOSL.ai tracks hardware, but the software running on it ages too. When an OS, runtime or database goes end-of-life the security patches stop. For software lifecycle dates we point to endoflife.ai. How hardware EOSL and software EOL differ
