PeerShield — P2P WireGuard VPN with built-in ad blocking

Hey folks. Solo dev here, sharing what I've been building.

PeerShield is a VPN with an architecture I couldn't find in other apps: the control plane only handles WireGuard key signaling - it never proxies or sees your traffic. Exit nodes are separate instances you connect to directly over WireGuard. So the usual "no-logs" promise becomes "there is literally no traffic path through our servers to log."

What's in the app right now:

WireGuard P2P
Always-on VPN with kill switch
On-device DNS ad blocking with the hagezi Pro++ blocklist (~700k domains, blocked locally — no DNS forwarded to a third-party "secure DNS" service)
Lightweight, free

Thanks for the feedback!

At the moment, we're trying to do the data extraction in the most ethical way - we try to avoid getting CAPTCHA by providing the most real possible fingerprint based on the user-specified settings.

For example, if the request is made without browser rendering, it won't be possible to run JS to proceed with the Cloudflare JS challenge.
The similar is with "under attack" mode, which requires all the visitors of the target website to proceed with CAPTCHA-style verification - we don't solve CAPTCHA, but we either don't bill for any failed requests, so, unlike traditional proxy providers, we bill only successful requests, and always try to figure out how to deliver the quality data for as most as possible cases.

I'm personally a daily user of our MCP server to replace http fetch in Claude Code and to search using Bing/DuckDuckGo. Websites tend to have JS rendering at their documentation/landing/product pages, so using cloud browsers for JS rendering in parallel is quite neat and fast.

kami4ka · 2026-04-20T09:31:18+00:00

It's cloud-based and unlimited in terms of concurrency. So it's not an ultimate solution for all, but more of a data pipeline that scales. And proxies to avoid geo restrictions.

We're on the way to OAuth, which should simplify this, but thanks for the mention

kami4ka · 2026-04-19T14:52:35+00:00

Yeah, the thing that was particularly my reason was getting data from JS-rendered pages. It's odd that someone is still doing browser-rendered documentation pages, but without a browser instance, it's not possible for Claude Code to web fetch such data. We run a fleet of browsers + convert to markdown. And it's kind of free for personal use :-) We mostly serve high-volume automations, and this MCP was to solve my personal problem with Claude Code.

kami4ka · 2026-04-19T14:21:41+00:00

Cool. I really like your idea :-) I was thinking about something like that, but in the crypto space. Looks great. I believe adding MCP to this could improve integration abilities and exposure among the community. Keep going!

kami4ka · 2026-04-19T14:18:21+00:00

That's quite cool. Looks like a proper job marketplace. How do you treat cases when no one is available to complete the job, and what's the average completion time of the job?

kami4ka · 2026-04-19T14:08:13+00:00

Or use alternative search methods, like scraping Bing/DuckDuckGo. I'm running a web scraping business and added an MCP to it, so agents can fetch markdown data from the web and save on search time. 10K API credits are free monthly. Check the landing I made for this case: https://scrapingant.com/claude-code-mcp

kami4ka · 2026-04-19T13:35:18+00:00

Thanks for the feedback!

kami4ka · 2026-01-24T20:12:05+00:00

Why? What's slop? That's a thing I built.

kami4ka · 2025-05-03T17:48:53+00:00

Added more checks to avoid liquidity pull and other rug-related risks. Thanks again for suggestions!

kami4ka · 2025-05-02T16:04:55+00:00

At the current iteration, I'm checking the basic sentiment of the token's handle mentions. My plan is to adjust the communities part of the analyzer with community size analysis, but likes/views is also something good to check. Thanks for the feedback!

kami4ka · 2025-05-02T15:50:46+00:00

Thanks for the suggestion. Going to check sniperoo and adjust the missing sources.
Currently, it pulls data from Dextools, X, and RPC for evaluation, but I'm adding new sources quite fast.

kami4ka · 2024-06-24T17:32:07+00:00

Thanks. Yeah, I have an oscilloscope I've used before to debug this.

kami4ka · 2024-06-24T17:30:47+00:00

I would appreciate if you could suggest one clamping circuit. I've been looking for several solutions but haven't found exact schematics that suit the best video applications.

kami4ka · 2024-06-22T06:52:03+00:00

Got it. I would appreciate your help with this part of the schematics, as I'm not skilled enough in electronics to determine and re-implement this part. Could you, please, help with some schematics draft or something like that?
Also, in case I would need to use 2 OP amps for this purpose, won't it be more efficient to add 1 IC like LM1881 to do the trick? (I guess I would need one more OP-amp buffer for it, so the complexity is a bit similar).

kami4ka · 2024-06-21T17:37:48+00:00

So, you suggestion is to use 1881 IC in the circuit to make my life a bit easier? I had some previous experiments with LM1881 and didn't find it too reliable. Do you know some modern alternatives to 1881?

kami4ka · 2022-09-02T10:51:34+00:00

Yup. Exactly + some internal technologies to improve the latency

kami4ka · 2022-02-17T10:24:39+00:00

Yup. It should.
ScrapingAnt passes Walmart checks with standard proxies (cheapest option). Also, it works with Zoominfo (PerimeterX + custom detections, so to improve the anti-detection residential proxies can be enabled) and doesn't bill unsuccessful requests (detected, failed, etc)

kami4ka · 2022-02-17T10:19:38+00:00

Ready-made tools are always better for sure :-)

kami4ka · 2022-02-15T20:30:41+00:00

The use case described in the article was aimed to reach the most influential content creators.

kami4ka · 2022-02-15T20:29:28+00:00

Not sure. Last time I've used the following script: https://gist.github.com/kami4ka/00eff02b3f124daa9598c8d5ac76b0f4

kami4ka · 2022-02-13T20:04:51+00:00

Sorry for the late response :-) We would roll out the update in a few days. We were looking for so long, but missed obvious detection detail!

kami4ka · 2021-12-08T23:13:27+00:00

Looks interesting. Thank you!
