Automated OpenSea Listing Expiry Alerts
Every morning, WebRun opens OpenSea, reads your active listings with their price and expiration date, works out which ones lapse in the next few days, sends the list to WhatsApp, and texts you by Twilio when something expires today, so relisting or repricing is a deliberate choice.
How do I get reminded before my OpenSea listings expire?
WebRun opens OpenSea every morning and reads your active listings with their asking price and expiration date, working out how many days each has left. It sends the soon to expire ones to WhatsApp and texts you by Twilio on a same-day expiry, so relisting or repricing is a deliberate decision.
- Listings never come off the market unnoticed
- A relist or reprice is a choice, not a discovery weeks later
- Nothing is ever listed, cancelled, or sold without you
Built for NFT collectors · digital artists · collection managers · crypto traders

How is each run configured?
Secure by default
Connect once, stays signed in
WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.
Every action is checked against this policy before it runs.
Questions, answered
Will it relist or cancel anything for me?
No. WebRun only reads your listings and reports their expiry dates. It never creates a listing, cancels one, accepts an offer, or signs a transaction of any kind, so nothing is ever traded on your behalf.
Does it need my wallet to sign anything?
No. Reading your own listings needs no signature and no transaction. Every action that would move an asset stays with you, taken in OpenSea yourself.
How far ahead does it warn me?
You set the window, commonly three days. Anything expiring inside it appears in the WhatsApp list, and a same-day expiry also triggers a text so it is not missed.
