Alternatives — Kevel
The Kevel alternative built for directories
Kevel (formerly Adzerk) gives engineering teams APIs to build their own custom ad server — powerful, but it's infrastructure, not a finished product. You bring the developers, the UI, and the directory logic. DirectoryAdServer is the opposite: a complete, self-hosted, flat-fee product purpose-built for directory ecosystems, with sponsored listings, ad-buy packages, and a modern self-serve advertiser portal ready on day one — no engineering required, and you keep 100% of your ad revenue.
Side by side
How we compare
Ready-to-use product, no engineering required
DirectoryAdServer ships a complete admin console and advertiser portal; Kevel is an API toolkit you build your own ad server on top of.
Built specifically for directories
Zones, sponsored listings, and packages model directory inventory directly; Kevel is general-purpose ad infrastructure.
Sponsored directory listings
Native top-of-category placements out of the box, not something you build from primitives.
Self-serve advertiser portal
A branded portal where advertisers self-serve creatives and reports is included; with Kevel you'd build that UI yourself.
Ad-buy packages mapped to products
Sell pre-built bundles that provision campaigns automatically; Kevel has no packaging layer tied to your store.
Flat fee — keep 100% of ad revenue
Pay one flat fee and keep every ad dollar; Kevel's API pricing scales with request volume.
Self-hosted ownership of your data
Kevel is a hosted API platform; your decisioning and reporting data run through their cloud.
Inventory limits & waitlists
Cap slots per zone and queue demand out of the box, not something you build from primitives.
Member sync from your directory
Pull existing members into advertisers instead of wiring the integration yourself.
Webhooks (Pabbly/Zapier)
Both can notify external systems; ours ships preconfigured directory-event webhooks.
Impression & click analytics
Both report delivery; ours is a finished dashboard, Kevel's is a reporting API you build on.
Flexible custom decisioning API
Kevel's strength is fully custom ad logic for teams that want to engineer their own server.
Comparison reflects DirectoryAdServer's directory-first feature set. Kevel's offering may change; verify current details on their site.
