Remote development does not always require a VPN. The right approach depends on whether you need to code on another machine, reach a private service, or share the output of a local app.
VPNs solve network access. They can be the right choice for employees who need private resources every day. They can be the wrong choice for a client who only needs to review one page, or for a developer who only needs a browser URL for a local build.
Remote development without VPN: choose the job
There are three common remote development needs:
- Code remotely: use a machine, container, or cloud environment as your dev box.
- Reach private resources: connect to internal services, databases, or tools.
- Share output: let someone open the app you are running locally.
Those jobs need different tools. A VPN may handle the second one. VS Code Remote Development, GitHub Codespaces, or dev containers may handle the first. A localhost tunnel handles the third.
Option 1: Remote IDE and server workflows
VS Code Remote Development lets you use a container, WSL, or remote machine as a full-featured development environment. Microsoft’s docs describe extensions that install VS Code Server on the remote OS so commands and extensions run there.
VS Code Remote Tunnels add a path without configuring SSH. You can run code tunnel or enable remote tunnel access through the VS Code UI. You then connect from VS Code or vscode.dev after authenticating with a GitHub or Microsoft account.
Use this when the code, tools, or compute should live somewhere else. It is strong for cloud VMs, desktops you leave at the office, GPU machines, or environments that are hard to recreate locally.
It is not a client review workflow. You connect as a developer with editor access.
Option 2: Cloud development environments
Cloud development environments move the dev box into managed infrastructure. GitHub Codespaces, Gitpod, Coder, and similar tools can give each developer a repeatable workspace.
Use this when onboarding speed, consistent tooling, or cloud compute matters. The tradeoff is platform cost, account setup, workspace lifecycle, secrets handling, and network policy.
Cloud dev environments may produce preview URLs, but that is a secondary feature. Their main job is to host the development environment.
Option 3: Private access without classic VPN
Some teams replace or narrow classic VPN usage with Zero Trust access products, mesh networks, or service-specific tunnels.
Cloudflare Tunnel uses cloudflared to create outbound-only connections from an origin to Cloudflare. Tailscale gives devices identity-aware network paths and can expose services through Funnel. These approaches can reduce inbound firewall exposure and make policy more granular than a legacy VPN.
They still serve access needs. They usually involve accounts, devices, policies, and service configuration. That is appropriate for employees and infrastructure. It can be heavy for outside review.
Option 4: Temporary tunnels for sharing output
Sometimes remote development only means this: “I built it here, and someone over there needs to see it.”
That does not require a VPN, a cloud dev box, or staging. It needs a scoped route from a reviewer browser to your local app.
wiremaven creates temporary encrypted public links for that job. Your app runs on a local port. Your machine connects to the wiremaven relay over an outbound-only WebSocket. The reviewer opens a browser URL. You see live viewer, request, and failure signals while the link is active.
Start from a local app:
npx wiremaven-cli 3000 --expires 30mReview windows can last 15, 30, or 60 minutes. During beta, wiremaven does not require an account. The reviewer does not need VPN access, editor access, or a dev environment.
Read the docs for setup and how wiremaven works for architecture.
How to choose
Use this decision table:
| Need | Best fit |
|---|---|
| Code on a remote machine | VS Code Remote, SSH, Codespaces |
| Standardize dev environments | Cloud dev environment |
| Reach internal employee tools | VPN, Zero Trust, or mesh network |
| Publish a private service through Cloudflare | Cloudflare Tunnel |
| Test external webhooks | ngrok or similar tunnel |
| Share one local build with a reviewer | wiremaven |
Review without giving away the environment
A VPN for a client review grants too much network context. A review link for employee network access gives too little governance. A cloud dev environment for a five-minute UI review adds cost and setup. The phrase remote development can blur coding access and review access. Keep them separate.
Give the reviewer access to the result through a review link. A temporary review link keeps the reviewer in the browser and keeps the dev environment under your control.
For the network comparison, read tunnel vs VPN. For VS Code specifics, read VS Code Tunnel. For review process, read review links for dev teams.
FAQ
Can I do remote development without a VPN?
Yes. Use remote IDEs, cloud development environments, Zero Trust access, mesh networks, or temporary tunnels depending on the job.
Is a tunnel a VPN replacement?
Not in general. A tunnel can replace VPN setup for one service or review session. It does not replace broad employee network access by itself.
What is the fastest way to show a local app remotely?
Run a temporary review link:
npx wiremaven-cli 3000 --expires 30mShould clients get remote development access?
Only if they are participating as developers. For review, send a scoped browser link instead of editor, machine, or network access.
