Sikur — everything the company sells
One product. The rest of the shelf is empty.
Vigil ships today. Nothing else is finished.
This page lists what you can install or buy right now, and says plainly that the list has one entry. An empty shelf is easier to check than a roadmap.
Vigil — monitoring that also does the restart.
Version 1.9.1, in its 14th release, sold and supported by the person who wrote it.
Vigil checks HTTP and TCP endpoints on a schedule, opens an incident when checks keep failing, fires a signed trigger at a recovery hook you control, probes again to see whether the fix actually worked, and publishes a status page for the people who would otherwise be emailing you. Two processes and one PostgreSQL database — no Redis, no message broker.
It is one host doing the checking, so it is not a substitute for a global probe network. That limit is on the home page and in the comparison pages, not in a footnote.
Free · AGPL-3.0
HTTP checks with keyword assertions, incidents that open themselves, a public status page and team roles. Same codebase, same two processes, no licence key and no telemetry. It exists so you can judge the engineering before deciding anything, and it is a perfectly good place to stop — github.com/artaspervyj-dotcom/vigil-core.
$149 once · source-available
The full repository — app, worker, tests, Docker, docs — with verified automatic recovery, unlimited deployments, monitors, seats and tenants, and the right to serve any number of clients from your own install. One-time and per company: 12 months of updates, then an optional $99/year that is never auto-charged, and every version you already hold stays licensed forever. Source-available, not open source — you own your copy, you do not get to resell it. The full text is published.
Run it before you buy it.
Five constraints every Sikur product is held to.
Each one costs something. The about page says what. In short:
The shelf is empty on purpose.
Sikur is not the Vigil company. Uptime monitoring is where it started, not the boundary. What follows may be infrastructure, developer tooling, desktop software, networking utilities or open-source libraries — picked because they are worth building, not because they extend a category.
Nothing else is announced, because nothing else is finished. Inventing names for products that do not exist would make this page longer and worth less. One idea is public before it exists — Vigil Cloud, managed hosting for the same product — and its page says outright that it is undecided and that the waiting list is how the decision gets made. That is the most anything gets here before it ships: an open question.
If there is a tool you want built, say so. It creates no commitment, and it is read by the person who writes the code.
The questions a one-product company gets.
Because there is one person. Sikur is run by Maria, who writes the code and answers the email. Vigil reached its 14th release before this page existed; a second product gets the same treatment or it does not ship. That is a real constraint on how fast the list grows, and it is stated here so you can price it in.
No, and nothing here implies otherwise. The $149 license covers Vigil: the source, unlimited deployments for your own business, private modification, and 12 months of updates to major version 1. Anything Sikur ships later is its own product at its own price.
You keep the source. Every version you have received stays licensed forever, so the product does not switch off when the company does, and there is no license server to call home to. Vigil Core is published under the AGPL-3.0, which cannot be withdrawn from releases already made. What neither of those gives you is a maintainer — that is the actual risk of buying from a company this small, and it is the reason the code is readable before you pay.
Yes — @s8kur on Telegram or s8kur3@gmail.com. It is not a vote and it does not create a commitment. The most useful thing you can send is a specific description of a problem you already pay to work around.
