HTML to Image gives developers a code-first alternative to Templated.io: raw HTML rendering, URL screenshots and named templates at a third of the entry price.
Disclosure: we built HTML to Image. We've kept this comparison honest because the alternative is search results full of low-effort listicles.

|---|---|---|
| Entry plan price | $29 / 1,000 credits (annual billing) | $9 / 1,000 credits |

| URL screenshots | No | Yes |
| JavaScript execution | No | Yes |
| Webhook delivery | Yes | Yes |

| Best for | teams designing templates in an editor and rendering variants | developers rendering their own HTML with templates on the same key |
Stay with Templated.io when non-technical team members own the designs and the workload spans video or PDF. Its drag-and-drop editor, Canva import and embeddable white-label editor are the product, and MP4 and PDF output come from the same credit pool. If your marketing team designs in a canvas and your renders include video, it fits.
Switch to HTML to Image when a developer is doing the integrating and the output is images. Every design on Templated.io has to exist as an editor template first, counted against a per-plan cap of 15 on Starter. Here, standard shapes are covered by the 25 named templates, anything custom is raw HTML with full CSS and JavaScript, URL screenshots ride on the same key, and 1,000 monthly renders cost $9 instead of $29 on annual billing.
A third of the price for the same volume. Both entry plans carry 1,000 renders a month; ours is $9, Templated.io's is $29 billed annually. The gap holds up the ladder — see the pricing page — and the free tier renews monthly instead of being a one-time 50 credits.
Raw HTML with real browser rendering. Templated.io renders canvas templates; it does not take arbitrary markup. Our HTML endpoint runs full CSS and JavaScript in headless Chrome, so charts, web fonts and dynamic layouts render exactly as they do in a browser. URL screenshots sit on the same key.
No caps to manage. All 25 templates are available on every plan, with no template counts or team-member seats to buy. Templated.io gates templates (15 on Starter, 100 on Scale) and team members by tier.
The editor workflow. Drag-and-drop design, AI template generation, Canva import and an embeddable white-label editor for your own users. If templates are designed by people who do not write HTML, that is the deciding feature.
Video and PDF output. MP4 renders and multi-page PDFs from the same credit system, which HTML to Image does not offer. Image-plus-video workloads stay on one vendor there.
# Templated.io (template render)
curl -X POST https://api.templated.io/v1/render \
-H 'Authorization: Bearer your-api-key' \
-H 'Content-Type: application/json' \
-d '{"template":"template-id","layers":{"text-1":{"text":"Hello"}}}'# HTML to Image (template render)
curl -X POST https://app.html2img.com/api/v1/templates/open-graph-image \
-H 'X-API-Key: your-key-here' \
-H 'Content-Type: application/json' \
-d '{"title":"Hello","subtitle":"From Northwind Studio"}'
Three concrete differences. Templates are selected by URL slug (/templates/{slug}) instead of a template ID in the body. Inputs are flat named JSON keys rather than a layers object of element properties. Auth uses an X-API-Key header instead of a Bearer token. Check the templates gallery to confirm the designs you need exist before migrating, or plan to rebuild them as HTML.
See the API parameters reference for the full request and response shape.
There is no crossover for image workloads: HTML to Image is cheaper at every tier. 1,000 renders is $9 versus $29. 5,000 renders is $25 to $60 versus $79 on Scale. 25,000 renders is $120 on our 30,000 plan versus $179 on Enterprise. Templated.io's prices are annual-billing figures, so the monthly-billing gap is wider still. The equation only changes if you need its video or PDF output, which our credits do not cover.
No. Our templates are pre-designed and rendered from a JSON payload, and anything custom goes through the raw HTML endpoint. If a non-technical team designs your templates in a browser canvas, Templated.io fits that workflow. If a developer is the one calling the API anyway, the editor is a layer you may not need.
At 1,000 renders a month both entry plans carry the same volume, but ours is $9 versus Templated.io's $29 on annual billing. At 5,000 renders HTML to Image is $25 to $60 across the 3,000 and 10,000 plans versus $79 on Scale. At 25,000 it is $120 on our 30,000 plan versus $179. The free tiers differ in kind: ours renews at 25 images every month, theirs is a one-time 50 credits.
No. HTML to Image renders PNG images only, while Templated.io also outputs MP4 video and PDF from the same credit pool. If video variants are on your roadmap, that is a genuine reason to pick Templated.io. For image-only workloads the credit maths above applies.
Not directly — Templated.io templates live in its canvas editor. You would rebuild the design as raw HTML for the HTML endpoint, use one of our 25 named templates, or commission a custom template through /contact. HTML and CSS give you more layout control than a canvas editor once rebuilt.
The free tier covers 25 renders a month with no credit card. Try the API against your real data before deciding.
No editor step, no template caps. Twenty-five pre-built designs on every plan. JSON in, PNG out, single API call.
