The short version

  • Only OpenWrt has a free tier, so it costs nothing to try first.
  • Each has a real cost: OpenWrt support is per device and per hardware revision, so a model number that worked last year may point at a different chipset this year and be unsupported.; ThousandEyes cisco does not publish a current definitive rate card, so any price a buyer finds online is likely outdated and should be confirmed directly with sales before budgeting
  • They diverge on capability: OpenWrt covers Package manager, ThousandEyes covers Path visualisation.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

OpenWrt

  • Support is per device and per hardware revision, so a model number that worked last year may point at a different chipset this year and be unsupported.
  • Flashing can brick a device permanently, and on hardware without a serial console or a recovery bootloader there is no way back.
  • Devices with 4MB or 8MB of flash have been dropped from recent releases, so a lot of older hardware is stuck on unsupported versions with known vulnerabilities.
  • Hardware acceleration for NAT and routing depends on vendor drivers, and enabling traffic shaping frequently cuts a gigabit connection to a fraction of its rated throughput.
  • A sysupgrade keeps your configuration but not your installed packages, so every release upgrade is followed by reinstalling and reconfiguring add-ons by hand.

ThousandEyes

  • Cisco does not publish a current definitive rate card, so any price a buyer finds online is likely outdated and should be confirmed directly with sales before budgeting
  • A 12-month minimum contract removes the option to trial the platform under real production load on a shorter commitment
  • Unit-based consumption billing across different test types is not always intuitive to forecast, and usage can grow unpredictably as more tests and agents are added
  • Since the Cisco acquisition, purchasing now runs through Cisco's broader enterprise sales and licensing process, which can be slower and less transparent than dealing with a smaller standalone vendor
  • Deep Cisco ecosystem integration is a real advantage only for organisations already standardised on Cisco; it offers less differentiated value for a non-Cisco shop
  • Endpoint agent pricing tiers (Essentials versus Advantage) gate meaningfully different capability, and choosing the wrong tier at signup can mean a contract renegotiation to get needed features

Answered from the vendors’ own pages

OpenWrt: How do I know my router is supported?

Check the Table of Hardware for your exact model and revision before buying or flashing. Do not assume that a supported model number means a supported unit; manufacturers change chipsets within a model.

ThousandEyes: Is ThousandEyes still sold as a standalone product after the Cisco acquisition?

Yes, it remains a distinct, purchasable product line rather than being merged into another Cisco offering.

OpenWrt: Is the OpenWrt One worth buying over a used router?

If you are evaluating OpenWrt rather than rescuing hardware you own, yes. It is supported by definition, has an unbrickable boot arrangement, and part of the price funds the project.

ThousandEyes: Is there a published, current price list?

No, Cisco does not publish a definitive current rate card; historical unit prices exist online but should not be treated as confirmed 2026 pricing.

OpenWrt: Will flashing void my warranty?

Almost always, and it may also break the ISP remote management your provider relies on for support. Keep the stock firmware image before you start.

ThousandEyes: What is the minimum contract length?

12 months.

OpenWrt: Is opkg still the package manager?

It is in the current stable releases, but development has moved towards apk, so expect package tooling and command syntax to change at the next major release.
