Live connections
Each connection with its process, destination, matched rule, route and throughput. Group by app or host, close a connection, or turn it into a rule in one click.
Network toolkit for developers
Every connection,
in plain sight.
Specola shows which process opened each connection, where it went and which rule sent it there — live, and for weeks afterwards. When you want a different path, write a rule in one TOML file.

The toolkit
Answer “what is this machine talking to, and why did it go that way?” without reaching for
ss, tcpdump and three browser tabs.
Connection history
Search the last 24 hours up to 90 days. Hour-by-day heatmaps, app-to-destination flows, why each connection ended, and CSV export.
Route map
See each route drawn from your machine through relay hops to its destination, with latency per hop and line width by throughput.
Rules
First-match rules on domain, IP-CIDR, GeoIP, port and process name. Send git through the office gateway and keep the browser direct.
DNS inspector
Per-domain resolvers, fallback and hosts, with every query, answer and latency in the log — so domain rules stay accurate.
Gateways & health checks
Group the HTTP, SOCKS5 and other upstreams you already use. Latency tests, automatic fallback and per-gateway traffic totals.
- Enhanced Mode
- Captures every app system-wide — including tools that ignore network environment variables.
- Plain TOML
- One readable profile you can diff, review and keep with your dotfiles.
- Headless core
- A C++20 core runs as a service; the UI and CLI talk to it over local RPC.
- Local by design
- History and logs stay on your disk. Nothing is sent to us.
How it works
Specola starts in observe-only Direct mode. Nothing changes until you add a rule.
-
Install and watch
Run Specola and open Connections. Every app's traffic appears with its process and destination.
-
Add rules where you need them
Declare the gateways you are authorized to use — a company gateway, a server you run — and write rules for the traffic that should use them.
-
Check the history
Days later, look up which rule a connection hit, how long it lasted and how much it moved.

FAQ
Is Specola a network service?
No. Specola is software that runs entirely on your computer. It does not come with servers, IP addresses, bandwidth or accounts on any network. It observes your machine's own connections and forwards traffic only to gateways you configure yourself, such as your company's gateway or a server you run.
Can I use it only to watch connections?
Yes. In Direct mode Specola changes nothing about where traffic goes; you still get the live connection list, history, route map and DNS log.
Which platforms are supported?
Specola is available for Windows today. macOS and Linux versions are coming soon. Check the manual for current requirements before buying — you can always request a refund within 14 days.
Can I try Specola before buying?
Yes. The current 0.x preview releases on GitHub Releases run without a license key. From version 1.0, Specola requires a license key to activate; a purchase covers all 1.x releases.
Is this a subscription?
No. You pay once and keep the license for the 1.x version series. There are no recurring charges.
Can I run it without the UI?
Yes. specola-core is a standalone process that reads the same TOML profile and can be controlled from the CLI or over its local RPC API.
What data does Specola collect?
Connection history, DNS and logs are stored locally on your device and are not sent to us. For license activation we handle only the information needed to issue and validate your license. See the Privacy Policy.
What am I allowed to use it for?
Any lawful use on networks and servers you are authorized to use. Using Specola for unauthorized access, unlawful interception or any other illegal activity is prohibited by our Terms and Conditions.
How do I move my license to a new computer?
Email [email protected] with your order number and we will reissue the license for your new device. Your receipt is in the Gumroad email you received after purchase.
