OnStage is an independent event guide that helps people discover concerts, sports, theatre, and family entertainment across the United States. Visitors can browse events by category, explore what is popular or happening soon, and find listings near them or in cities such as Las Vegas, New York, Chicago, Atlanta, and Los Angeles. The site features a broad mix of live experiences, from touring musicals, comedy, and music performances to sporting events, fairs, dinosaur attractions, and family shows.

For listed events, OnStage presents dates, locations, categories, and available starting prices, helping visitors compare options before following links to ticket sellers. Ticket purchases are completed through those sellers rather than OnStage. The guide says prices shown exclude service fees, and the final price appears on the seller’s website. OnStage may earn a commission when visitors buy through its links, but states that this does not affect ticket prices. Event data is provided by Ticketmaster; OnStage notes that it is not affiliated with or endorsed by Ticketmaster.
