Does Urlbox have a CLI for AI agents?

Yes. Urlbox documents @urlbox/cli and an installable agent skill. The CLI can render screenshots, PDFs, and videos, and can use URLBOX_API_SECRET in CI or agent environments.

Is Grabbit cheaper than Urlbox?

At 10,000 standard screenshots a month under this page’s assumptions, Grabbit costs $250 in the first year and Urlbox Ultra costs $1,188 a year. Urlbox can consume extra render units for some work, so the request mix matters.

Does Urlbox have a hosted MCP server?

No hosted MCP endpoint was found in the first-party documentation reviewed September 29, 2026. Urlbox does publish an official CLI and installable agent skill.

Do Grabbit annual credits expire?

Yes. Unused annual subscription credits expire at the end of the term. Cancellation takes effect at term end, so the credits remain available until then. Separately purchased prepaid top-up credits do not expire while the account remains active.

Can both APIs run screenshots asynchronously?

Yes. Urlbox has an async render endpoint, polling, and signed webhooks. Grabbit accepts Prefer: respond-async, returns HTTP 202, supports polling by grab id, and sends signed completion webhooks.

What output formats does Urlbox have that Grabbit does not?

Urlbox documents PDF, SVG, MP4, WebM, and Markdown in addition to image formats. Grabbit returns PNG, JPEG, or WebP.

What changes in the API response during migration?

The illustrated Urlbox response has renderUrl, size, renderTime, and queueTime. Grabbit returns image_url, bytes, execution_ms, status, and id.

Can a Grabbit test key evaluate image quality?

No. A test key returns a fixed placeholder for request and result wiring. Use a live key with available credits to inspect a real page capture.

When should I keep Urlbox?

Keep Urlbox when the workflow depends on PDF or video, rendered Markdown, storage integrations, its official CLI and skill, or enterprise controls that Grabbit does not publish.

Grabbit vs Urlbox

Choose Grabbit for flat annual credits and a hosted MCP endpoint. Choose Urlbox when its broader render formats, storage integrations, enterprise controls, or mature CLI fit your workflow.

Reviewed by the Grabbit product team. We checked public first-party documentation, pricing pages, and Grabbit production behavior. Controlled cross-provider image and speed tests are not part of this release.

Public pricing

Named tiers, allowances, and quota rules

Entry-tier math can hide volume discounts and different billing units. These are the public tiers behind the decision, kept separate instead of normalized into one rate.

Tier	Price	Allowance	Extra cost or discount	Quota and fit	Source
Lo-Fi	$19 / monthly	2,000+ render units$0.0095 per included unit	No overage published	Low-quality third-party thumbnails; successful renders consume quota.	Urlbox pricing, checked Sep 29, 2026
Hi-Fi	$49 / monthly	5,000+ render units$0.0098 per included unit	No overage published	Suitable for most standard screenshot jobs.	Urlbox pricing, checked Sep 29, 2026
Ultra	$99 / monthly	15,000+ render units$0.0066 per included unit	No overage published	Adds broader capture coverage and priority support.	Urlbox pricing, checked Sep 29, 2026
Business	$495 base / monthly	$495 base, then $3 per 1,000 render units	Overage: $3 per 1,000 render units after the base	Increased limits, SLA, security, and dedicated support.	Urlbox pricing, checked Sep 29, 2026
Enterprise	From $3,000 / monthly	Custom or unlimited	No overage published	Custom clusters, limits, contracts, and infrastructure options.	Urlbox pricing, checked Sep 29, 2026

Workload cost

What do Grabbit and Urlbox cost for the same monthly volume?

Named-plan rates only become useful after a workload is applied. These scenarios choose the lowest listed plan that covers each volume and show the first twelve months of cash cost.

Workload	Grabbit, annual	Urlbox, annual	Plan and assumption
Evaluation100 / month	$50	$228	Urlbox Lo-Fi. Grabbit uses part of its 25,000 annual subscription credits. Urlbox commits to 2,000 or more render units each month.
Small production2,000 / month	$50	$228	Urlbox Lo-Fi. Both fit the named allowance. Lo-Fi is positioned for lower-quality thumbnails, so quality requirements can force a higher Urlbox tier.
Growing production10,000 / month	$250	$1,188	Urlbox Ultra. Grabbit uses the annual grant plus four 25,000-credit top-ups. Urlbox uses 15,000 or more monthly render units.
High-volume production100,000 / month	$2,400	$5,940 base, plus usage	Urlbox Business. The public Business price is a $495 monthly base plus usage, so $5,940 is a floor rather than a complete quote. Grabbit uses its annual grant plus the lowest-cost mix of published top-ups.

Assumptions: Twelve equal months, one successful standard screenshot per requested capture, public list prices, no tax, no failed requests, and no Urlbox render-unit multipliers. Urlbox uses the listed monthly rates because no annual discount is applied. Grabbit annual subscription credits expire at term end; separately purchased top-up credits do not expire while the account remains active.

Methodology

Pricing uses the public Hi-Fi monthly price and included render units, checked September 29, 2026.
Feature and agent claims come from Urlbox API, render-option, and CLI documentation.
No cross-vendor speed or image-quality benchmark was run for this release.

Capture capabilities

Full-page and viewport capture with waiting and selector controls
Image, PDF, video, rendered-link, and storage workflows
Cookie-banner handling plus a wider set of render formats than Grabbit

Best-fit scenarios

Use Urlbox when PDF, video, storage integrations, or enterprise controls matter.
Use Grabbit when a hosted MCP endpoint and one-credit successful screenshots matter more.

Migration notes

Map Urlbox URL or CLI options to the Grabbit POST /v1/grabs JSON body.
Replace project key and secret signing with a Grabbit Bearer key or MCP OAuth.
Rework PDF, video, and storage-integration flows because Grabbit returns hosted image captures.

Migration map

How do you move screenshot requests from Urlbox to Grabbit?

The examples capture the same public page as a 1440 by 900 full-page WebP. Keep the provider-specific features called out in the map instead of silently dropping them.

Urlbox request

curl -X POST https://api.urlbox.com/v1/render/sync \
  -H "Authorization: Bearer $URLBOX_SECRET" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com",
    "format": "webp",
    "width": 1440,
    "height": 900,
    "full_page": true
  }'

Grabbit request

curl -X POST https://api.grabbit.live/v1/grabs \
  -H "Authorization: Bearer $GRABBIT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com",
    "format": "webp",
    "width": 1440,
    "height": 900,
    "full_page": true
  }'

Urlbox response

{
  "renderUrl": "https://renders.urlbox.com/...webp",
  "size": 310517,
  "renderTime": 6609,
  "queueTime": 127
}

Grabbit response

{
  "id": "<grab_id>",
  "status": "done",
  "image_url": "https://<host>/<image>.webp",
  "bytes": 123456,
  "execution_ms": 2345
}

Intent	Urlbox	Grabbit	Migration caveat
Target	url	url	Direct mapping.
Viewport	width, height	width, height	Grabbit accepts widths from 320 to 1,920 and heights from 240 to 1,080.

Grabbit CLI

npx grabbit.live https://example.com --width 1440 --height 900 --format webp --full-page

MCP prompt

Capture https://example.com as a full-page WebP at 1440 by 900. Return the image and image_url.

Agent experience

What changes when an AI agent owns the screenshot step?

Which product gives an agent a hosted tool?

Grabbit publishes a hosted Streamable HTTP MCP endpoint with OAuth or Bearer authentication. No Urlbox-hosted MCP endpoint was found in the first-party docs reviewed, but Urlbox publishes an official CLI and installable agent skill.

How does an agent recover when Grabbit returns 402?

Call get_usage before a live run or after credits_exhausted, then add a prepaid top-up or wait for the next annual subscription grant. A test key only validates wiring with a placeholder.

What result should the model consume?

Grabbit MCP can return image content plus image_url. Keep image_url as the portable artifact when the client or model cannot accept an image block.

What this comparison does not claim

Urlbox has more render formats and storage integrations than Grabbit.
Urlbox documents a CLI and agent skill, so older comparisons that list no agent support are stale.
This page does not claim speed or image-quality superiority because version one did not run controlled cross-vendor captures.
Grabbit accepts public URLs and image outputs only. It does not replace Urlbox PDF, SVG, video, or storage workflows.
