Agentic Development\nstarts here

Give your AI agents real-world capabilities. Isolated sandboxes, headless browsers, code execution, persistent file storage, and transactional email — all from a single API.

AGENT PRIMITIVES

Every primitive your agent needs

Stop wiring together five vendors. One SDK gives your agents sandboxed compute, browser automation, code execution, file storage, and email — with consistent APIs and unified billing.

Sandboxes

Isolated Linux environments that spin up in milliseconds.

Browsers

Headless Chromium instances for scraping, testing, and interaction.

Code execution

Run Python, Node, Go, Rust, and 50+ languages in secure runtimes.

File storage

S3-compatible object storage with per-agent namespacing.

Agent email

Send and receive email programmatically with 99.9% delivery.

PERFORMANCE

Built for speed at scale

Every primitive is optimized for the latency-sensitive world of autonomous agents.

<200ms

COLD START

Sandboxes boot in under 200ms. Warm instances respond instantly.

50+

LANGUAGES

Python, Node, Go, Rust, Java, Ruby, and more — all sandboxed.

COMPATIBLE STORAGE

Use any S3 client library. Per-agent buckets with lifecycle policies.

99.9%

EMAIL DELIVERY

Transactional email infrastructure with DKIM, SPF, and DMARC.

SIMPLIFY YOUR STACK

One platform vs five vendors

Stop piecing together E2B, Browserbase, Modal, S3, and Postmark. Get everything in one place.

THE FRANKENSTACK

Five vendors, five bills, five APIs

E2B for sandboxes
Browserbase for headless browsers
Modal or Lambda for code execution
AWS S3 for file storage
Postmark or SES for email

THE TRANSACTIONAL WAY

One platform, one API, one bill

Sandboxes with sub-200ms cold starts
Managed Chromium with stealth mode
Multi-language code execution
S3-compatible storage built in
Transactional email with 99.9% delivery

BENEFITS

Why agent builders choose Transactional

Ship Faster

One SDK, one set of docs, one dashboard. Spend time building agent logic, not integrating infrastructure.

Pay Less

Unified billing with usage-based pricing. No minimum commits, no idle charges across five separate vendors.

Debug Easier

Correlated logs across sandboxes, browsers, and email. Trace a single agent run from boot to completion.
