The short version

  • Only PartyKit has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bitdefender VPN the network is not Bitdefender's: the servers and the Catapult Hydra protocol are licensed from Aura, formerly Pango and AnchorFree, so the company physically handling your traffic and subject to legal process is a United States based third party, not the Romanian vendor whose brand is on the client.; PartyKit documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
  • They diverge on capability: Bitdefender VPN covers Suite integration, PartyKit covers Stateful edge servers.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bitdefender VPN

  • The network is not Bitdefender's: the servers and the Catapult Hydra protocol are licensed from Aura, formerly Pango and AnchorFree, so the company physically handling your traffic and subject to legal process is a United States based third party, not the Romanian vendor whose brand is on the client.
  • Catapult Hydra is proprietary and closed source, so unlike OpenVPN or WireGuard there is no public implementation for researchers to audit, and a buyer choosing on cryptographic grounds has nothing to inspect.
  • There is no published independent no-logs audit of this service comparable to the Deloitte, PwC and KPMG engagements the standalone VPN vendors commission, so the no-logging position rests on the privacy policies of two separate companies rather than on any external assurance.
  • The free tier bundled with the antivirus suites is capped at a small daily allowance and selects the server for you, so it is a demonstration rather than a usable VPN, and customers who assumed their suite included a VPN find they need a further paid upgrade.
  • Feature depth is well below the dedicated market: no port forwarding, no dedicated IP, no multi-hop, no city-level server selection and no Linux or router client, so routers, NAS devices, consoles and anything needing an inbound connection cannot be covered at all.

PartyKit

  • Documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
  • Commercial free tier requires deploying to the user's own Cloudflare account, adding setup complexity.
  • Storage on the free Individual plan clears every 24 hours, limiting it to prototyping rather than persistent production data.
  • Smaller ecosystem and community than more established realtime infrastructure providers.

Answered from the vendors’ own pages

Bitdefender VPN: Who actually operates the servers?

The underlying VPN network and the Catapult Hydra protocol are licensed from Aura, previously known as Pango and AnchorFree, the operator of Hotspot Shield. Bitdefender identifies the arrangement in its VPN terms. Your traffic therefore passes through a United States based provider's infrastructure.

PartyKit: How much does PartyKit cost?

PartyKit is completely free. Both the Individual and Commercial plans have no upfront costs.

Source
Bitdefender VPN: Is the free version enough?

Only as a taster. It is capped at a small daily traffic allowance and chooses the server itself, which rules out streaming and any sustained use. It exists to demonstrate the feature inside the antivirus suite.

PartyKit: What is PartyKit's Individual plan?

The Individual plan is free and includes deployment to a global edge platform, support for up to 10 live projects, and is suitable for small projects. Storage is cleared every 24 hours.

Source
Bitdefender VPN: Has the no-logs claim been independently audited?

There is no published independent no-logs audit of this service equivalent to those commissioned by the dedicated VPN providers. If an audited no-logging claim is what you are buying, this is not the product for it.

PartyKit: What is PartyKit's Commercial plan?

The Commercial plan is free but requires deploying to your own Cloudflare account. It includes custom domains, unlimited projects, and you pay only your Cloudflare usage costs.

Source
Bitdefender VPN: Does it work with streaming services?

Sometimes, but it is not built around that use case, there is no per-service server labelling, and there is no commitment to restoring access when a platform blocks a range. A streaming-focused provider is a better fit if that is the reason you want a VPN.

PartyKit: Can I upgrade from Individual to Commercial plan?

Yes, both plans are free but offer different feature sets. The Commercial plan removes project restrictions but requires managing your own Cloudflare infrastructure.

Source
Bitdefender VPN: Can I run it on Linux or a router?

No. There is no Linux client and no router firmware or manual configuration option, so coverage is limited to the Windows, macOS, iOS and Android clients.
