For freelancers and small agencies running client automations

Bad news should never come from your client.

Euclio watches the automations you run for clients, and what actually arrives on the other end. You know the moment anything goes wrong, and the answer is ready before they ask.

Answer ready

Tue 2:14pm, your client: "Sarah says she didn't get her reminder — is the booking thing ok?"

The ledger: paused 9:02–9:14am. Caught at 9:03. Four reminders due in the gap, four arrived.

"Yes — a 12-minute pause Tuesday morning, caught it in one. All four reminders due in that window were delivered. Confirmed, not guessed. Nothing you need to do."

You knew first. The answer was ready
How it works

Three moments.

01

Minute one.

The booking sync stops at 9:02am. You know by 9:03, not from a client. And Euclio's canary receives what your clients' customers receive, so a workflow that runs but sends the wrong thing gets caught too.

The sending end · heartbeat
last check-in 9:02am · missed 9:03am
Where every monitoring tool watches from. It knows the workflow ran.
The receiving end · canary
reminder arrived 9:01am · on schedule
Where Euclio also stands. Sent and arrived are different facts. It knows both.
02

Message one.

Weeks in, the text arrives: "is it working?" What they mean is: did Sarah get her reminder. The ledger has already assembled that answer, so replying is reading, not digging.

The Euclio ledger for one client: a resolved 12-minute incident with its events and matched receipts, quiet runs of 26 and 58 days, and the record kept twelve months.
Ledger open at 2:15pm. The reply took two minutes; the scramble it replaced took forty-four.
03

Month twelve.

Renewal. The ledger shows every catch and every quiet day since day one. The fee explains itself.

The request above is the entire footprint: no package installed, nothing hooked into your runtime. Token filled in; Python and curl too. One silent address in the send list covers the canary. Two minutes by hand, less if your coding agent does it. The rest we'll show you.
Evidence

The first months are the loud ones

A new client checks everything. Every glitch they hear about secondhand becomes a question, and every question is a small audit of the fee. The questions stop when the first few answers are exact.

"For pricing, I'd separate three things: build fee, monitoring fee, improvement budget. If bundled, clients treat every tweak like it was included."

"Most of my clients don't want to deal with anything technical and just throw money at the problems to solve them."

Clients rarely leave because something broke. They leave because they stopped hearing anything and assumed the worst. An exact answer is the cheapest insurance there is.

Scope

What Euclio does and doesn't do

Does

  • +Flags the moment a workflow stops, so you find out first
  • +Catches the reason too, when you opt in: error text scrubbed before it leaves your machine, deleted after 30 days
  • +Canary verification: receives what your clients' customers receive, so arrival is a fact, not a guess
  • +Accounts for every gap: sends due during a pause, sends arrived after
  • +Keeps a ledger per client, in their language, with exact timestamps
  • +Turns any incident into a one-message answer
  • +Drafts the optional client note from the facts, in your voice

Doesn't

  • −Contact your clients. You send everything, or nothing
  • −Show clients a dashboard, a login, or the word "Euclio"
  • −Guess. "Nothing was missed" is yours to say, after checking
  • −Let AI talk to your clients. The words that carry meaning are yours, and the product enforces it
  • −Install anything. No package in your code, no plugin in your platform. The whole footprint is one request
  • −Become a dependency. If Euclio is ever down, your workflows run like it doesn't exist
  • −Rebuild or touch your automations

Why I'm building this

The message every automation freelancer dreads isn't “something broke.” It's the client reporting it first. Euclio is my fix: know first, answer with receipts.

Nobody's using it yet. This page reserves a spot before it opens.

Next: checking each send looks right, not just that it arrived. After that, a pause switch for misfiring workflows and an expiry radar for tokens.
