LocalCan is the closest real competitor: a macOS app whose tagline is “Local domains and persistent Public URLs”, also sold as a one-time purchase. This page is the honest version of the comparison, both directions. Facts about LocalCan were checked in August 2026; their product moves — see localcan.com for today's details.
Where we agree
Both are macOS apps. Both are one-time purchases in a field of subscriptions. Both give local projects real domains and real public URLs. If you've already decided against renting a tunnel by the month, either app is that decision — the differences are in what each one believes the job is.
Traffic inspection: their feature, our refusal
LocalCan offers traffic inspection and webhook replay. Those are genuinely useful debugging tools, and this is a real trade, not a gotcha: Localdock is built so that inspecting your traffic is impossible. It reads the hostname, then forwards raw TCP without looking further — and the invariant behind the whole product is that nothing about your processes ever leaves your machine. We chose the other side of the trade and built the product around it.
Persistent URLs vs links that die
LocalCan's public URLs are persistent. Localdock's are key-gated and expire after an hour, on purpose. Both positions have honest costs: a persistent URL is a standing exposure you have to remember exists; an expiring one can't run a long-lived demo without being re-shared. Localdock's view is that a link that dies is a link you can't leak — and that re-sharing is one click, so the safety is cheap.
Agent-native, or not the point
As of August 2026, agent tooling isn't part of LocalCan's public pitch. Localdock is built for it: names that follow whatever port a Claude Code or Cursor session grabbed, per-session attribution with an honest “unknown origin”, and an MCP server — list_ports, get_free_port, cleanup — so parallel agents reserve ports instead of colliding on them. If two or three agent sessions are your normal working day, this section is probably the decision.
One control vs a feature list
LocalCan is the bigger tool with the bigger feature list — custom domains, inspection, replay. Localdock is deliberately the smaller one: a single Reach control with three rungs — this Mac, your Wi-Fi, the internet — and a menubar list of what's running. Both are one-time purchases; the question isn't which is more software, it's which shape of tool you want open all day.
When LocalCan is the better choice
When you want persistent public URLs; when you want them on your own custom domain; when traffic inspection and webhook replay are debugging tools you'll actually use. Those are real features and LocalCan is good at them. Localdock will not grow them — the refusal is the product.
Questions
Can I run Localdock and LocalCan side by side?
Nothing conflicts by design, though tools in this category may both want port 80 — Localdock steps aside to 7777 automatically when something else owns it, and tells you which port is live.
Is either a subscription?
No — both are one-time purchases, which is part of why they end up compared. Localdock's licence covers a single device, with version 1 updates included.
Does Localdock inspect my traffic?
No, and it can't — by design. It reads the hostname and then splices raw TCP without looking further, and the product invariant is that nothing about your processes ever leaves your machine. If webhook inspection and replay is a workflow you want, that's a real reason to pick LocalCan.
