The short version

  • Only CLion has a free tier, so it costs nothing to try first.
  • Each has a real cost: CLion specific subscription pricing not listed on product page; Dahua Technology dahua is named under NDAA Section 889 and listed on the FCC Covered List, so the US federal government cannot procure its video surveillance equipment and cannot contract with entities that use it, which disqualifies most organisations with any federal contracting ambition regardless of how good the software is.

Where each one falls short

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

CLion

  • Specific subscription pricing not listed on product page
  • Requires reference to separate store page for tier details
  • AI credits needed for integrated AI features
  • No mention of free trial for commercial use

Dahua Technology

  • Dahua is named under NDAA Section 889 and listed on the FCC Covered List, so the US federal government cannot procure its video surveillance equipment and cannot contract with entities that use it, which disqualifies most organisations with any federal contracting ambition regardless of how good the software is.
  • Rules adopted by the FCC in late 2025 gave the Commission authority to revoke equipment authorisations already granted, so equipment that is legal to sell today may not be tomorrow and a multi-year rollout carries regulatory risk the vendor cannot indemnify.
  • Sourcing has degraded sharply: new equipment, replacement parts and system expansions are increasingly difficult to obtain through compliant US distribution and major retailers have removed listings, so an installed estate faces a spares problem long before end of life.
  • Any organisation that later wins or bids for federal work, or supplies a federal contractor, must audit and replace Dahua equipment across all its facilities under Section 889(a)(1)(B), turning a cheap installation into an expensive forced rip-out.
  • Beyond procurement law, insurers, auditors and enterprise customers increasingly treat Chinese-manufactured surveillance as a supply chain finding in its own right, so the reputational cost lands even where the legal prohibition does not.

Answered from the vendors’ own pages

CLion: Is CLion free?

CLion offers free licenses for students, teachers, and non-commercial use. Commercial users can purchase subscriptions with organization pricing available.

Source
Dahua Technology: Can a US federal agency buy Dahua?

No. Dahua is explicitly named under NDAA Section 889, so federal agencies cannot procure or obtain its video surveillance equipment, including OEM-rebadged versions.

CLion: What free options does CLion provide?

CLion provides non-commercial use licenses for open-source and hobby projects, plus full licenses for students and teachers without cost.

Source
Dahua Technology: Can a private US company use Dahua cameras?

Section 889 does not directly regulate private companies without federal contracts, and existing installations are not required to be removed. But the moment the company bids for federal work or supplies a federal contractor, Section 889(a)(1)(B) makes the installed equipment a problem.

CLion: Does CLion include AI assistance?

Yes, CLion natively integrates AI with support for Claude, GPT, Gemini, and Grok models. Users can apply JetBrains AI credits or bring their own API keys to avoid vendor lock-in.

Source
Dahua Technology: Is existing Dahua equipment banned?

No. The prohibition on new authorisations does not apply retroactively to equipment authorised before February 2023, and legacy systems may remain in use. New purchases and expansions are the restricted part.

CLion: Are there discounts for switching to CLion?

CLion offers a competitive discount of 25% for users switching from other IDEs and similar products.

Source
Dahua Technology: Is Dahua available outside the United States?
