KingSumo alternative: how Vast compares for creators

Updated 11 November 2026 · By the Vast team

KingSumo is the cheapest way to pay once: its free plan has unlimited giveaways and referral entries, and Pro is a $49 one-time deal on AppSumo. Vast's Basic plan is $15 a month or $108 a year, so KingSumo costs less over time. Pick Vast if your giveaway is for a game, a stream or a Discord server: KingSumo says it has no Twitch entries and doesn't verify follows.

Vast is our product, so weigh that. We read KingSumo's pricing page, its own comparison page and its AppSumo listing on November 11, 2026. Prices are in US dollars and can change, so confirm on KingSumo's pricing page before you decide.

What do you get with KingSumo's $49 lifetime deal?

KingSumo's pricing page shows a Lifetime Plan at "$49 Single Payment," next to a crossed-out $228, with a Buy Now on AppSumo button. Over the free plan it adds custom branding, Meta Pixel and conversion tracking, custom rules and terms, extra entry fields (first name, last name and phone), advanced integrations (Mailchimp, ConvertKit, Klaviyo and a custom API) and an option to "Remove Sponsored Entry."

The AppSumo listing calls it "Lifetime access" and says it's "Refundable up to 60 days." KingSumo's own comparison page, written by AppSumo's founder, says Pro replaces KingSumo's badge with your logo but keeps a small "Powered by KingSumo" line, so there's no full white label.

A lifetime deal is one payment for the plan as it's sold. Read AppSumo's deal terms for what future updates the license covers.

Is the lifetime deal cheaper than Vast?

Usually, yes. $49 once is a little over three months of Vast's Basic at $15 a month, and less than half of Basic's $108 yearly price. If KingSumo's free plan or Pro does what you need, it's the cheaper choice once you'd have paid for four months of Basic.

Vast's free plan costs nothing too, but it's smaller: one giveaway a month, with one prize, one winner and one action of each type. Drafts count toward that one giveaway. It includes official rules drafted for you, a random draw, an embed and the same entry actions as paid plans, apart from custom actions, email list sign-ups and loyalty bonuses.

Who wins. KingSumo, on price.

Which works better for streamers and game creators?

KingSumo's comparison page is frank about this. It lists "No TikTok, Twitch or comment picking," and says: "Follows are credited when the fan clicks through. We don't verify the follow happened." Its homepage gives subscribing to a YouTube channel as an example bonus entry, and pitches new Instagram, Twitter and Facebook followers.

Vast checks Twitch follows, subscriptions and channel reward redemptions through the Twitch account the player connects, and Steam wishlists, plays, ownership and group joins the same way. Kick, X and Discord actions are there too, but aren't checked automatically today, so look over winners before you announce them. On Basic, loyalty bonuses give extra entries to players who've entered your other giveaways, which suits streamers who run one every week.

Who wins. Vast, for Twitch, Steam and game communities.

Which is better for growing an email list?

KingSumo is built for it. Every entrant gives an email address, and by default each friend who enters through an entrant's referral link earns that entrant 3 more entries. The free plan connects to Zapier and SendFox, and reminder emails go to entrants halfway through and on the last day.

On Vast, entrants enter with a Vast account, or give a name and email in the embedded widget. The email list sign-up action, which adds entrants to Mailchimp, MailerLite, beehiiv, Brevo, HubSpot or Kit, starts on Pro at $49 a month. Our guide to growing an email list with giveaways covers consent and setup.

Who wins. KingSumo, clearly.

Can an AI agent set up the giveaway?

On Vast, yes. An agent such as Claude Code connects to Vast's MCP server with an API key, drafts the giveaway, adds entry actions, previews it and reports entries. It publishes only when you ask. Today, API keys for agents need a paid plan, and Basic at $15 a month is the cheapest. See running a giveaway with an AI agent.

KingSumo's Pro includes a custom API "to build your own integrations." We found no MCP server or AI agent documentation on its site.

Who wins. Vast.
