Desktop and mobile: Admins set up rules and manage policies on a computer, but receive real-time device and service alerts on mobile to act on warnings immediately. Sample screens on a computer and a phone, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Nightlatch shows every device on your home or small office network and tells you when a new one joins or an always-on one goes missing. It also checks that your web services answer, and how fast.
It is for home users, small business admins and people who run their own servers, and who find scripts and self-hosted dashboards tiring to set up. A small agent runs on a Raspberry Pi, mini PC or NAS and reports to a clean app you open on your phone.
Unlike a bare scanner, it names and groups devices for you, lets you write alert rules by device, hour and group, and sends alerts where you already look. You can keep all data on your own hardware or use a light hosted view.
- Tagline
- Know who is on your network, and when something goes quiet.

- Why this name
- A latch is a small, simple lock you trust at night. The name suggests quiet watching over a home or small office network without alarm bells.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Unknown device alerts
Get a push or email the moment a device you have not approved joins the WiFi or LAN, with its name guess, maker and time seen.
No member yet
Missing device warnings
Mark cameras, servers and hubs as always-on. Nightlatch warns when one drops off, after a grace period you set.
No member yet
Web service checks
Watch your sites and self-hosted apps for HTTP status and response time, with alerts on errors or slow replies.
No member yet
Automatic naming and groups
Devices are labelled by maker and type, then sorted into groups like Family, Guests, IoT and Servers. Rename anytime.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- No loop in the product. Reaches customers through content, open-source communities and search for people replacing self-hosted scanners. Users do not naturally bring in others through use; only a shared status page could add light exposure.
- Do they become customers?
- Home and small-office admins who see it are likely buyers themselves, but only through search or community posts. Test whether free-tier home users upgrade for history and integrations.
- First customers
- Self-hosters and home lab owners who already run a LAN scanner and want phone alerts and history, then very small offices with no IT staff.
- Where to reach them
- Self-hosting communities: Share a free agent and a write-up on moving off script-based scanners in home lab forums and subreddits.
- GitHub and open-source lists: Publish the open agent and a comparison guide so people searching for LAN scanners find it.
- Small IT consultants: Offer a trial to freelancers who look after small offices, to place Nightlatch at several sites.
- First milestone
- Fifty active free installs and ten paying users on the Plus tier within ninety days.

RisksAI inference
- TechnicalA PWA cannot scan the network itself. The agent needs install on a Pi, NAS or mini PC, and that step may put off non-technical users.
- CommercialThe main alternative is free and open source. Users may not pay unless hosted alerts, history and ease clearly beat self-hosting.
- DataDevice lists and network activity are sensitive. A hosted view must limit what is uploaded and be clear about it.
- PlatformPush alerts on iPhone PWAs depend on the platform's web push support, so email or chat alerts must work as a backup.
- TechnicalDevice naming from MAC addresses is imperfect, and randomised MACs on phones may cause false unknown-device alerts.
