Hi guys.
You can use the Flippa search tools quickly drill into different website facets (site age, traffic or revenue). Otherwise check out the advanced search options at https://flippa.com/search
If none of the open listings are what you are interested in, you can hit the Watch this Tag or Save this Search link and we'll let you know if any new sites that meet this criteria are put up for sale.
We also allow tags which can help you find more application-oriented websites for sale. A few examples include https://flippa.com/buy/sitetype/application (where sellers have tagged the website as an application) or https://flippa.com/buy/implementation/ruby (where the sellers have tagged the implementation of the site as ruby).
If none of the open listings are what you are interested in, you can hit the Watch this Tag or Save this Search link and we'll let you know if any new sites that meet this criteria are put up for sale.
Hope that helps.
