Run PDF rendering via a dedicated render service, not inside your serverless functions: browser engines in functions impact app speed, waste development time, and increase infrastructure costs.
CPU PRESSURE
Heavy rendering competes with your core API paths and can slow down user-facing requests.
RAM SPIKES
Chromium/Playwright/Puppeteer workloads create memory spikes and instability under load.
EXECUTION TIMEOUTS
Long documents and complex templates often exceed serverless execution limits.
CHROMIUM COMPLEXITY
Maintaining headless browser tooling in production introduces brittle runtime edge cases.
STORAGE + BANDWIDTH
You still need to build storage, signed URL delivery, and large file transfer plumbing.
SURPRISE BILLS
Render bursts, traffic spikes, and document retention can inflate infrastructure costs fast.
Offload PDF generation instead of building PDF infrastructure in-house
ServerlessPDF removes the heavy PDF infrastructure layer from your app so your team can ship faster and spend less time on operational work.
BUILDING PDF INFRASTRUCTURE IN-HOUSE
- ×Time goes into browser tooling, storage, and delivery plumbing instead of product work.
- ×Heavy PDF jobs put extra pressure on your app runtime and user-facing requests.
- ×Your team owns signed downloads, file lifecycle rules, and production troubleshooting.
- ×Rendering issues take longer to diagnose when they live inside your application stack.
USING SERVERLESSPDF
- ✓Integrate quickly with a simple SDK/API flow and minimal app-side code.
- ✓Render workloads run outside your app runtime, helping keep product paths lighter.
- ✓Storage, signed download delivery, and retention handling are already built into the flow.
- ✓Clear statuses and error codes make support and maintenance easier.
Short version: keep PDF infrastructure out of your app and offload the heavy work to ServerlessPDF.
