Sikur — the company behind Vigil
A small software company that ships things you can read.
Independent, self-funded, and deliberately not in a hurry.
Sikur builds engineering tools. Vigil is the first one. There is no venture money behind it, no growth team, and no roadmap written by anyone but the person maintaining the code.
One engineer, named, reachable.
Sikur is run by Maria. Not a team page of stock photographs, not a support queue — the person who writes the code is the person who answers the email. That is a real limitation as much as a feature, and it is stated here so you can price it in.
Buying software from a company you have never heard of is a reasonable thing to hesitate over. The answer Sikur offers is not a testimonial wall; it is that almost everything is published before you pay — the source of the free edition, the full license text, the architecture, the release history and the limitations.
How the free and paid editions relateFive rules the products are held to.
These are constraints, not values statements. Each one costs something.
Self-hosted by default
A Sikur product should keep working if Sikur disappears. Vigil holds your monitors, incidents and history in your Postgres, on your server. There is no license server to call home to, and nothing stops working when a subscription lapses — because there is no subscription.
Not "anonymous" telemetry — none
The product does not phone home. This website sets no cookies, runs no analytics and loads nothing from a third party — even the fonts are served from this domain. The cost is that we genuinely do not know how many people use Vigil. That is the trade.
Source, license, docs, limits
The free edition is the same codebase. You can install it, read how the checker decides something is down, and judge the engineering before spending anything. A product that has to be bought before it can be inspected is asking for trust it has not earned.
Including where a competitor wins
Every product page names what the product is wrong for and what to buy instead. Vigil checks from one host, so it is not a substitute for multi-region probes; the comparison pages say so plainly and recommend the alternative. Omitting a limitation is a lie with extra steps.
Software, not rent
Vigil is a one-time license for the source. Not every future product can work that way, but where it can, it will. The version you hold stays licensed forever, whatever happens to the company.
The company is broader than the product.
Sikur is not "the Vigil company". Vigil is what exists today. What follows may be infrastructure, developer tooling, desktop software, networking utilities or open-source libraries — chosen because they are worth building, not because they extend a category.
Nothing else is announced, because nothing else is finished. When something is, it will appear on the products page with the same rules applied to it.
