Before you read on

Bannerflow is a different class of tool: an enterprise ad stack that designs HTML5, video and static ads and delivers them to more than a hundred ad platforms, programmatic and DOOH networks included. If you run display campaigns at that scale, we do not replace it — we make images, not campaigns.

The differences, plainly

What	Bannerflow	Shareglint
Pricing	Sales-led, custom pricing — "We offer customized pricing based on the features you need"; no public price list	Public prices: Starter $9 for 2,000 renders; 100 a month free, watermarked
Built for	Enterprise brands, in-house creative teams and agencies running display, social, DOOH and feed-driven campaigns	Developers generating images from code and data
Ad formats	HTML5, video, static and GIF ads per their homepage; the export-format details sit in a help article behind a login, which we could not verify	PNG, JPEG, WebP, one-page PDF; GIF and MP4 up to 5 s; no HTML5 ads
Ad platforms	Google Marketing Platform, The Trade Desk, Amazon Ads, Meta, TikTok, DOOH networks and more	None — you upload or publish the images yourself
Developer API	No public API documentation found on their site	REST API, webhooks, signed URLs and an MCP server on every plan
Getting started	Book a demo	Sign up and render on the free plan

Bannerflow pricing (sales-led, custom pricing, no public plans or prices; demo on request) comes from their own public page, checked 2026-11. If something has changed — tell us and we will fix it.

Which one to pick

Take Bannerflow

An in-house creative team or agency produces and serves ad campaigns across many networks, with budget for an enterprise contract.

Take Shareglint

You need images from code — ad variants, social cards, OG images — at a public price, and you place them yourself.

What migrating looks like

You rewrite the template once, as HTML and CSS. Preview costs no quota, so getting the layout right is free. Then you swap a single call on your side.

curl -X POST "https://shareglint.com/v1/images?wait=true" \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"template":"blog-og","modifications":{"title":"...","author":"..."}}'
