Embed eSignatures Directly Into Your Website or App

This looks too complicated. My team doesn't have time for a long integration project.

We designed our widget for speed. With clear documentation and simple code snippets, a developer can embed a full signing experience into your app in under an hour. We even have a free API plan so you can build a proof-of-concept with zero risk.

Why not just build this ourselves? It's just a signature box.

It's much more than a box. It's security, compliance (ESIGN, UETA, GDPR), audit trails, data validation, and scalability. Building and maintaining this is a six-figure project. We provide it all, battle-tested and ready to go, for a fraction of the cost, letting your team focus on your core product.

I'm worried about redirecting my users to another site. It feels unprofessional and I might lose them.

That's exactly the problem our embedded widget solves. The entire signing process happens within your website or application. You control the branding and user flow, creating a seamless, professional experience that increases trust and document completion rates.

Is it really legally binding and secure enough for my industry?

Yes. eSignly is built on a foundation of enterprise-grade security and compliance. We hold ISO 27001, SOC 2 Type II, HIPAA, and GDPR compliance, and our signatures meet global legal standards. Every signed document comes with a comprehensive, court-admissible audit trail.

1. Configure Your Experience

Define your document fields, branding, and signing logic directly within our intuitive dashboard. Whether you need custom form fields or specific signer sequences, our setup process is point-and-click, not code-intensive.

2. Embed the Widget

Copy our lightweight, secure JavaScript snippet and drop it into your application's frontend. It is fully responsive and optimized to work seamlessly with React, Vue, Angular, and standard HTML—ensuring a native feel without the development headache.

3. Collect & Sync Data

Your users sign documents without ever leaving your ecosystem. We instantly sync signed PDFs and tamper-proof audit trails back to your backend via secure webhooks, keeping your data synchronized and your business moving forward.

Go Live in Hours

Forget long development cycles. Our developer-first design, clear documentation, and simple code snippets mean you can implement a proof-of-concept today and go live this week. Get your first API document signed in under an hour.

Boost Conversions

Redirecting users to sign is a major point of friction and drop-off. By keeping the entire process within your platform, you can increase document completion rates by up to 40% and accelerate your revenue cycle.

Total Brand Control

Don't let a third-party brand dilute your user experience. Our widget is fully customizable with CSS, allowing you to match your brand's look and feel perfectly for a truly native, white-labeled experience.

Bank-Grade Security

Security isn't an afterthought; it's our foundation. With SOC 2 Type II, ISO 27001, and PCI DSS compliance, you can be confident that your data and your users' data are protected by enterprise-grade security protocols.

Ironclad Compliance

Our signatures are legally binding under the ESIGN Act, UETA, and eIDAS. We also ensure compliance with industry-specific regulations like HIPAA and 21 CFR Part 11, complete with a court-admissible audit trail for every document.

Avoid Build Costs

Building a compliant e-signature solution in-house is a $100k+ project with ongoing maintenance and legal risks. Leverage our battle-tested infrastructure for a fraction of the cost and keep your engineers focused on your core product.
