The DocuSign + Zoom + Calendly alternative.

Published July 26, 2026 · OmniStrat AI

The best alternative to DocuSign, Zoom and Calendly isn’t three tools wired together — it’s one attested room. That’s OmniStrat AI. The alternative to running DocuSign, Zoom, and Calendly separately is one attested room: OmniStrat Agora schedules the meeting, hosts it, and captures a legally valid e-signature in a single workflow. Producing one sealed, tamper-evident record instead of three disconnected logs across three vendors.

What the three-tool stack costs

Beyond cost, the deeper problem is evidentiary: the booking, the recording, and the signed document live in three systems with nothing cryptographically linking them. If anyone disputes what was scheduled, said, or agreed, three separate vendor logs are not one provable record.

One attested room instead

Scheduling is where the workflow starts: you publish a booking page, and whoever opens the link picks from times you are genuinely free. They need no account, and they never see your calendar. Only the open slots, because the page returns free times and nothing else. Confirming the slot creates the verified room in the same step, and stores its id on the booking. That is the join the three-tool stack does not have.

Agora runs schedule → meet → sign as one workflow. Every step produces a cryptographic receipt: who was in the room, what was agreed, and tamper-evident proof the record was never altered afterward. Content sealed and private by default. Signatures are Ed25519, per party, hash-chained and publicly verifiable. We do not represent this as a substitute for a qualified electronic signature under ESIGN, UETA or eIDAS; if your matter requires that, talk to us about what we do and do not attest. This is Proof of Consent.

What one room gives you that three integrated tools cannot

The saving is the smallest part of the argument. What the integrated stack cannot reproduce, at any price, is a single record:

• One record instead of three logs. Schedule, meeting and signature are events on a single hash-chained ledger, each committed to the one before it. Nothing has to be reassembled from three exports.
• Verification with no account. A regulator or counterparty re-hashes the payload and checks the Ed25519 signature at omnistrat.ai/verify.html, without logging into any vendor and without our help.
• Media that never touches our servers. The meeting runs peer-to-peer over WebRTC, so there is no recording in a cloud to secure, retain or leak. The evidence is the signed chain of what happened, not a video file.
• Encrypted identity until signing. For hiring, candidates stay anonymous until both parties sign, and the match is a tri-party signature no three-tool stack can produce.
• One price, one Passport. Against roughly $74 per user per month for the three business tiers, the whole workflow runs under a single Passport. Free and Solo open in periodic windows.

Built for hiring. Internal or external

Hiring is the workflow where the three-tool stack lives, and where the law now demands more than logs: the Illinois AI Video Interview Act requires notice and consent for AI-analyzed interviews, NYC Local Law 144 requires bias audits, and Colorado’s ADMT law requires notice and explanation. Run interviews in Agora and consent is attested on the record; route AI screening through Foundry and every decision carries a verifiable per-decision receipt. Bias auditing itself is your auditor's job, we produce the records they work from.

When the incumbent stack is enough

If you never need to prove what happened, no compliance exposure, no disputes, no hiring laws touching you, the incumbent stack works, and there is no reason to move. The switch matters when a record must hold up: audits, placements, client consent, regulated advice.
