Undetectable.io Mobile Proxies: Bulk Import and Scripted Rotation

Undetectable.io is the antidetect browser we suggest first, and it is a comfortable home for operators who run many profiles on Windows or macOS. Each profile keeps its own fingerprint and its own proxy, profiles can live locally or in the cloud, and paid plans add proxy import so a whole list of lines arrives in one step. Where automation-minded teams save the most time, though, is on the network side: generating proxy lists, checking line health and rotating IPs from code. NeonProxies lines are built for exactly that, with a rotation link and an API on every US carrier line. This guide shows how to keep the browser side tidy and push the repetitive network work into scripts.

Where the work splits between browser and network

Undetectable.io owns the identity: fingerprint, cookies, storage and the proxy stored with each profile, plus a proxy check that confirms the address before you open it. It accepts HTTP or SOCKS5 with a login and password, which matches the two ports on every NeonProxies line.

NeonProxies owns the connection: which line is online, which IP it currently holds and when it should change. Our API exposes status and rotation for every line, so the parts of the day that are pure repetition, such as giving each profile a fresh address before a batch of checks, can run without anyone clicking.

• Browser side: one Undetectable.io profile per identity, proxy stored inside
• Network side: line status and rotation through the NeonProxies API
• Shared key: a mapping table of profile names to line identifiers
• Human step: opening profiles, which stays deliberate and visible

Loading many lines at once

Typing credentials into dozens of profiles is slow and error-prone. On paid Undetectable.io plans, proxy import lets you load a prepared list instead. Copy the lines you need from your NeonProxies dashboard, arrange them in the format the import screen asks for, and bring them in together. The free plan, with up to five cloud profiles, is enough to test the flow before you scale it.

Generate that list from your mapping table rather than by hand, so the order of lines matches the order of profiles you intend to create. A short script that reads the table and prints one line per entry is all it takes. Keep the output file out of shared folders and delete it after import.

Checking one profile before the batch

Before trusting an import, prove a single line end to end. It takes a few minutes and gives you a reference point if anything in the batch misbehaves later.

When that profile is right, the rest of the import is the same data in the same shape, and the proxy check on each new profile becomes a quick confirmation rather than a hunt.

1. Create one Undetectable.io profile and choose local or cloud storage.
2. Enter a NeonProxies line in the proxy settings, using SOCKS5 and its port, with the login and password.
3. Run the proxy check and confirm a US carrier IP in the metro you ordered.
4. Let timezone, language and geolocation follow the IP, and set WebRTC to use the proxy's address.
5. Open the profile and confirm the address on an IP lookup page matches the check.

Scripted rotation around profile sessions

Lines hold their IP until rotated, and rotations are unlimited with no wait between changes. That makes a small scheduler genuinely useful. Before a working block, a script can walk the mapping table, rotate each line whose profile is closed, wait until every line reports online through our API, and then post a short note that the profiles are ready to open.

The one rule to encode is never to rotate a line while its profile is open. Have operators mark a profile as in use, or simply rotate only outside working hours, and the script cannot pull an IP out from under a logged-in account. After any rotation, the operator reopens the profile so it starts on the new address.

Keeping a large roster consistent

Use one line per profile for anything that signs in. Group lines by metro in the dashboard and name profiles to match, so the mapping table, the dashboard and Undetectable.io all tell the same story. On bigger plans, profiles can be shared with team members, so an operator opens an identity with its line attached instead of copying credentials around.

When a profile needs a new city, use the free self-service location move in your dashboard, update the city in the mapping table, and run the proxy check in the profile so the timezone follows the new IP. A nightly script that compares each line's reported city with the table catches anything that drifted.

• One line per signed-in profile, grouped by metro
• Mapping table as the single source of truth
• Profile sharing on bigger plans instead of passing passwords
• A nightly status check against the table

Troubleshooting the pipeline

If imported profiles fail the proxy check, look at the generated list first: a missing field or the HTTP port paired with SOCKS5 breaks every entry after it. If a profile opens just after a rotation and pages time out, the script probably did not wait for the line to report online. If a location looks wrong, a manual timezone may have been set before the line was attached.

Unexpected sign-outs almost always trace back to a rotation while a profile was open. Tighten the in-use check in your scheduler and the problem disappears.
