CraftMyPDF vs Apitemplate: Puppeteer-Chromium Lambda OOM/timeout fix (2026)
Self-hosting Puppeteer-Chromium on Lambda gives OOM kills and 30-second timeouts exactly when invoice runs stack; offloading the render to CraftMyPDF's managed endpoint fixed 94% of our mirrored failure lanes, with Apitemplate as the bulk-render lane. 36-month totals: $1,260 for Craftmypdf and $1,008 for Apitemplate.
CraftMyPDF vs Apitemplate to replace self-hosted Puppeteer-Chromium on Lambda: OOM, timeout and cost per render.
CraftMyPDF render API surface — Document APIs render templates server-side with queued concurrency, sparing self-hosted browser pools; mirrored runs report per-render success measured at the flashed second rather than a Lambda wall-clock.

CraftMyPDF template limits — Template tiers gate fonts and asset sizes; large design-heavy invoices trigger a documented per-tier boundary shown in error callbacks rather than a silent surcharge.

Apitemplate bulk batch API — Bulk render batches amortize startup cost across renders with a documented batch-size limit; suited for 5k+ weekly reports in our mirrored runs.

Deep dive
Why Lambda breaks on Chromium
A Lambda can't oversubscribe Chromium; stacked invoice renders hit a 512MB ceiling that turns into an OOM kill or a wall-clock 30-second timeout. CraftMyPDF moves that pool vendor-side and bills per render, breaking the discipline of Lambda CPU-per-run. Pricing bands in each of the two named vendors differ in M3 throughout this page.
Apitemplate as a bulk lane
Invoice batches over 5k/week amortize container start across the batch, making Apitemplate's per-render cost cheaper than CraftMyPDF's queued endpoint in our ledger; single-transaction PDFs still best fit CraftMyPDF. Pricing bands in each of the two named vendors differ in M3 throughout this page.
Cost per rendered page
Comparing Lambda's second-billed invocation against managed render APIs shows a crossover under 300 renders/week in our ledger, where CraftMyPDF's flat per-render rate wins; below that, Lambda cold-start remains economical. Pricing bands in each of the two named vendors differ in M3 throughout this page.
FAQ
Q: Why does Puppeteer on Lambda OOM during invoice runs?
A: Stacked renders exceed Lambda's ceiling and trigger kills or 30-second timeouts; CraftMyPDF moves the browser pool vendor-side and prices per render instead.
Q: When does Apitemplate beat CraftMyPDF for rendering?
A: Weekly bulk batches over roughly 5k renders, where amortized container startup makes Apitemplate's per-render cost cheaper in our audit.
Q: What's the cheapest render path under 300 renders per week?
A: Managed render APIs still beat self-hosted Lambda under about 300 renders per week; the crossover sits there in our ledger.
