Nebula is a scalable overlay networking tool with a focus on performance, simplicity and security. It lets you seamlessly connect computers anywhere in the world. It can be used to connect a small number of devices, but is also able to connect tens of thousands of devices.

Nebula incorporates a number of existing concepts like encryption, security groups, certificates, and tunneling, and each of those individual pieces existed before Nebula in various forms.

### 5/5 — Just works!

*2025-09-23, version 0.5.1*

Never had any issues with the app and I find it more reliable and performant when using relays than tailscale!!

### 3/5 — Need more granular control

*2025-04-06, version 0.5.1*

the app is generally good but lack of more granular control compared with a dedicated configuration file. for example, i have no control over inbound rules which leads to problems that even another node cannot ping me.

### 1/5 — Doesn’t work

*2024-11-11*

App creates a VPN profile, but connection fails to establish. No logs generated.

### 4/5 — Great Concept

*2024-11-07, version 0.4.2*

Love it but needs on demand vpn features to auto-connect when trying to access specified domains or IPs. Also needs mobileconfig to be able to push settings from MDM server

### 3/5 — Need to be able to use a custom DNS server

*2023-05-09, version 0.2.0*

I really really want to use Nebula on my phone, but the lack of custom dns servers is kind of a dealbreaker for me. Like I want Nebula to use a device connected to the mesh as the DNS server instead of whatever iOS decides to use. Similar to how you can specify the DNS in a WireGuard config.

### 5/5 — Nebula is great

*2023-04-03, version 0.2.0*

I’m loving Nebula in general. The iOS app is also good. Only two things I would request: the ability to route all traffic over the nebula tunnel like an oldschool VPN (assuming appropriate unsafe routes are set) and also the ability to set the DNS servers on iOS.

Thanks for the awesomeness!

### 3/5 — A bit of a step backwards

*2022-12-26, version 0.2.0*

As my more forgiving, detailed prior review seems to have been deleted, I'll leave a succinct review: the network extension is a bit hang-y if you keep the overlay network running.  Your whole iPad will need a reboot about once a day if you leave this running.  Older version didn't do that.

It's too bad.  Nebula is cool on other platforms.  The iOS client is clunky and janky and crashy.

### 5/5 — Works well

*2021-05-05, version 0.0.38*

Can easily access my internal web sites even when they are behind a double NAT. Highly recommend.

### 5/5 — Fantastic

*2021-02-17*

Nicely done guys, love your tech. Thanks for providing a free app for us, sounds like you have a lot more GUI/management stuff in the pipeline.

Looking forward to the IPv6 update!
