Snapoena vs ProofSnap - Comparing Web Evidence Capture Tools

What ProofSnap Does Well

ProofSnap is a Chrome extension that captures web pages directly from your browser. It has built a solid feature set for evidence collection:

• SHA-256 and RSA-4096 cryptographic signatures. ProofSnap hashes each capture and signs it with RSA-4096, which provides strong proof that the evidence has not been tampered with after collection.
• Blockchain timestamps. Capture hashes are anchored to a blockchain, creating a public record of when the evidence was collected.
• DOM and metadata capture.Beyond screenshots, ProofSnap preserves the page's DOM structure and metadata, giving you more than just a visual record.
• Chrome extension convenience. One click in your browser captures the page you are viewing right now - including pages that require authentication.

These are real strengths. ProofSnap takes evidence capture seriously and delivers a product that goes well beyond a basic screenshot.

Where Snapoena Takes a Different Approach

Snapoena was designed around a different philosophy: capture should happen on a neutral server, timestamps should follow established legal standards, and the evidence package should include everything a court might ask for.

• Server-side capture for third-party trust. ProofSnap captures from your browser - your machine, your network, your environment. Snapoena captures from its own servers. This is a meaningful distinction. When evidence comes from a neutral third party rather than the party presenting it, it is harder to challenge. Opposing counsel cannot argue that you edited the page in dev tools before capturing.
• RFC 3161 timestamps vs blockchain timestamps. This is one of the biggest differences. RFC 3161 is a well-established standard where an independent Time Stamp Authority cryptographically signs the hash. Courts have accepted RFC 3161 timestamps for years. Blockchain timestamps are technically valid, but they are newer to the legal system and may face skepticism from judges unfamiliar with the technology.
• WHOIS and DNS records included. Snapoena captures domain registration and DNS data alongside every evidence package. This establishes who owned and controlled the domain at the time of capture - critical context for UDRP disputes, trademark cases, and DMCA takedowns. ProofSnap does not capture these records.
• Evidence bundle ZIP. Snapoena packages everything into a single downloadable ZIP - screenshot, HTML source, timestamp token, WHOIS data, DNS records, PDF report, and verification instructions. One file, ready to attach to a legal filing.
• Free tier with full features. Snapoena offers a free tier that includes the same capture capabilities - server-side capture, cryptographic hashing, RFC 3161 timestamps, and evidence bundles. ProofSnap offers a 7-day trial, after which you must subscribe at $8.99 to $24.99 per month to continue using the service.
• No extension installation required. Snapoena is a web app. You paste a URL and click capture. There is nothing to install, no browser compatibility to worry about, and it works from any device with a web browser.
• Bulk capture mode.Need to capture 20 URLs at once? Snapoena's bulk capture mode lets you submit multiple URLs in a single session, which saves significant time when documenting widespread infringement or monitoring multiple pages.

When ProofSnap Might Be the Better Choice

ProofSnap's browser extension approach has a genuine advantage in one important scenario: capturing authenticated pages. If you need to preserve evidence from a page that requires a login - a private social media profile, an internal dashboard, a members-only forum - a browser extension captures exactly what you see in your authenticated session. Server-side tools cannot access pages behind your login without additional configuration.

If most of your evidence capture involves authenticated content and you are comfortable with a browser extension workflow, ProofSnap handles that use case natively.

When Snapoena Is the Better Choice

For publicly accessible web pages - which represent the majority of evidence capture scenarios in DMCA, UDRP, and trademark disputes - Snapoena offers several structural advantages:

• Server-side capture from a neutral third party carries more weight than a capture from your own browser
• RFC 3161 timestamps follow a court-recognized standard with decades of legal precedent
• WHOIS and DNS records provide domain ownership context that ProofSnap does not include
• The free tier lets you evaluate and use the tool without a credit card or time-limited trial
• No installation means your team can start capturing evidence immediately from any device
• Bulk capture handles large-scale documentation efficiently

The Bottom Line

ProofSnap and Snapoena are both serious evidence capture tools - neither is a toy. The choice comes down to your priorities. If you primarily capture authenticated pages and prefer a browser extension workflow, ProofSnap is a reasonable option. If you want server-side neutrality, RFC 3161 timestamps that courts already recognize, WHOIS and DNS records, and a free tier to get started, Snapoena is built for that.

Both tools are better than a plain screenshot. The question is which approach gives your evidence the strongest foundation when it matters most.
