GeneratedTrusted in production
Image infrastructure your production workflows can rely on.
Teams use HCTI to power publishing workflows, internal reports, product features, and customer-facing tools.
Shocked at how easy this was to get running. Pasted in the example, added my key. It just works.

Three ways to capture
Write the markup, capture a live webpage, or fill a reusable template. Each path ends at the same image API—and you can try all three below.
URL screenshots
Capture a full page, exact viewport, or selected element from a live public webpage.
Templates
Save the design once, then send structured values for every new image you need.
Preparing the live playground
Loading it just before you reach this section keeps the initial page fast.
Integrate
From a prompt, a workflow, or your application.
Connect HCTI to an AI client, automate image and PDF generation in your existing workflows, or call the REST API from any language.
MCP + AI
Give your AI tools a real image API.
Connect through OAuth, then create images and PDFs, capture live URLs, and work with reusable templates directly from the conversation.

Any MCP client
I use HCTI with my Claude Code and NetClaw agents over MCP to generate social media, web, and YouTube content every month. Tremendously valuable.

No-code & automation
Connect HCTI to thousands of apps.
Use an automation platform to bring image generation into the workflows you already run.
REST API + clients
One simple REST API. Use any language.
Send HTML, a URL, or template values as JSON. Call the API directly with any HTTP library, or use one of our typed clients.

Less browser babysitting. More finished assets.
The API handles rendering infrastructure while you keep control over the content, browser, output, and delivery.

Capture the exact browser state
Control the viewport, selector, device scale, color scheme, delays, and full-page behavior without maintaining Chromium yourself.
Keep designs structured and reusable
Version templates, define named values, and generate consistent variations without sending the whole design every time.
Generate variations in batches
Turn one design into a collection of finished images with multiple value sets in a single workflow.
Create images and PDFs through one API
Use the same rendering model for share images, reports, receipts, webpage captures, and downloadable documents.
Page metadataCached renderLink preview
Open Graph image automation
Give every page a current image when it gets shared.
Publish one stable og:image URL pattern. HCTI reads each page’s metadata, renders the matching screenshot or template, and reuses it until the inputs change.
Saved infrastructure
Keep storage and proxy configuration out of every request.
Configure object storage destinations and authenticated proxies once at the organization level. Image requests reference opaque IDs, so credentials stay out of application payloads.
Write rendered files directly to your bucket, keep your existing CDN and retention policies, and optionally disable HCTI file storage.

Requests send destination and proxy IDs—not connection credentials.

Start free, then scale with the amount you render.
Every account includes 50 images each month. Move to a monthly image volume that fits production, then add higher-volume capacity as your automation grows.
Plans apply to the organization rather than individual seats, so bringing collaborators into the workflow does not multiply the bill.
