Timestamp Anything.Prove Everything.
Create cryptographic proof that something existed at a specific moment. No accounts. No uploads. No trust required.
Three Steps to Unbreakable Proof
No accounts. No sign-ups. Just cryptographic certainty.
Enter Your Content
Type a message or attach a file. Everything stays in your browser — we never see your data.
We Generate Proof
Your content is hashed and signed with Ed25519 — the same cryptography used by Signal and SSH.
Share & Verify
Get a QR code and link. Anyone can verify your proof instantly — no app or account needed.
Create Your Proof
What do you want to timestamp?
Why STAMPEDSAFE?
The fastest way to create tamper-proof timestamps
Military-Grade Security
Ed25519 digital signatures with SHA-256 hashing. The same cryptography protecting billions in cryptocurrency.
True Zero-Knowledge
Your data never leaves your browser. We physically cannot see, store, or access your content. Ever.
Instant Verification
Anyone can verify your proof by scanning a QR code. No downloads, no accounts, no friction.
Works Forever
Proofs are self-contained and mathematically valid. They work offline, even if we disappear.
Perfect For
Protecting Ideas
Timestamp inventions, designs, and concepts before sharing with investors or partners.
"Timestamped my app concept before the pitch meeting"
Sealing Documents
Prove contracts, agreements, and records existed at a specific moment.
"Sealed the signed NDA for our records"
Logging Decisions
Create an immutable record of architectural decisions, code commits, and specifications.
"Documented our API design before v2 launch"
Capturing Evidence
Timestamp photos, screenshots, and recordings the moment you capture them.
"Proved when I documented the product defect"
Better Than The Alternatives
STAMPEDSAFE combines the best of all worlds: free, instant, private, and cryptographically secure.
Built for People Who Ship
“I timestamp every invention disclosure before sharing with potential partners. Simple habit that's already protected me twice.”
“Finally, a timestamping tool that doesn't require blockchain gas fees or trusting a third party with sensitive data.”
“We timestamp all research notes before publication. The QR verification makes peer review so much smoother.”
Frequently Asked Questions
Blockchain timestamping is powerful but slow (10+ min confirmations), expensive (gas fees), and public (your hash is visible forever). STAMPEDSAFE is instant, free, and completely private — your data never leaves your device.
Cryptographic timestamps are increasingly accepted as supporting evidence in legal proceedings. Many users combine STAMPEDSAFE proofs with traditional documentation. For legal matters, always consult an attorney in your jurisdiction.
Your proofs are completely self-contained — they verify mathematically without any server. Even if we disappear tomorrow, your timestamps remain valid forever because the cryptography doesn't depend on us.
No. All cryptographic operations happen locally in your browser. Your messages, files, and proofs never touch our servers. We have no database of user content — we literally cannot see what you timestamp.
Ed25519 is an industry-standard signature scheme used by Signal, SSH, cryptocurrency wallets, and countless security-critical applications. It's been rigorously analyzed by cryptographers worldwide and is considered secure against all known attacks.
Absolutely. The Free tier gives you 5 proofs per month. For higher volume, upgrade to Pro (500/month) or Unlimited. Many businesses use STAMPEDSAFE to protect IP before client presentations.
