Armory

Overview

Armory is a free, open-source Bitcoin wallet built around generating and storing private keys. It is best suited to Bitcoin users who want to separate key storage from transaction preparation and are willing to manage their own security. Its standout proposition is a deliberate offline-signing workflow, with the responsibility and technical care that workflow demands.

Key features

Armory keeps private-key data on an offline computer while an online watching-only wallet monitors payments and prepares transactions. The transaction then moves between environments: create it online, sign it offline, and broadcast it online. That separation suits cold storage, but it asks users to handle the process correctly rather than treating security as a service performed for them.

For shared control, Armory supports distributed multi-signature addresses through Lockboxes. Other wallet tools include printable one-time backups, multiple wallets, GPU-resistant encryption, key importing and sweeping, and message signing. Together these make it more than a simple balance viewer, though the emphasis remains on Bitcoin key management.

The download page describes Armory 0.96.0 as compatible with Bitcoin Core 0.14.0 and later, including SegWit. Developers can consult source code, Python usage documentation, and wallet-format references. Installer verification instructions and signed hash files support GPG checks, a useful option for users who want to verify downloads before installing.

Armory says users control private-key generation and storage and must protect their bitcoins themselves. Support resources include an FAQ, troubleshooting material, public forums, and a support portal; the team cautions that it cannot personally answer every email. Businesses can also seek enterprise Bitcoin-security consulting, including custom features or code.

Pricing

Armory Wallet is free: free, with cold storage and multi-signature support. There is no free trial because the wallet is offered as a free plan. That removes a subscription decision, but it does not remove the practical cost of maintaining an offline computer and taking responsibility for key security. Enterprise consulting is also offered, with custom pricing.

Platforms

Armory supports Windows, macOS, Ubuntu/Linux, and Raspberry Pi, and its peer transfers support Bitcoin movement between wallets. The download page lists version 0.96.0 for 64-bit Windows and Ubuntu/Debian, and version 0.95.1 for 64-bit Mac OS X. The homepage says August 2026 updates made Armory usable as an iOS mobile app. Those version differences matter to desktop users choosing an installer; the published download versions are not uniform across operating systems.

Who it's for

Armory is a strong fit for Bitcoin holders who want offline private-key storage, a watching-only online wallet, or distributed multi-signature control, and who are prepared to handle backup and verification steps. Developers may value the source repository and technical references. It is a weaker fit for someone seeking a general-purpose wallet across many currencies or a hands-off security model: Armory is a Bitcoin wallet, and users remain accountable for protecting their keys.

Pros and cons

• Pro: Offline key storage paired with online transaction preparation creates a defined cold-storage process for users who want to keep signing keys off the network.
• Pro: Lockboxes provide distributed multi-signature addresses, while printable backups and key importing and sweeping add useful key-management options.
• Pro: Signed hashes and GPG verification instructions give users a way to check installers, and developer references make the project more inspectable.
• Con: Users bear responsibility for key generation and safeguarding, so mistakes in handling keys or backups can have serious consequences.
• Con: Desktop download versions differ by operating system, and the listed Mac release is older than the Windows and Ubuntu/Debian release.
• Con: Support relies on self-service resources and community channels in part; the team does not promise a personal response to every email.

Alternatives

For a wallet with a broader stated platform range and publicly hosted client code, consider Coin Wallet, which is free and supports Android, iOS, Linux, macOS, web, and Windows. Guarda Wallet is another free option across mobile, desktop, browser extension, and web; its stated pricing says there is no platform fee, though network and possible third-party provider fees apply.

If the need is contactless or online payment rather than Bitcoin cold storage, Apple Pay and Google Pay are free payment alternatives, with Apple Pay available on Apple-oriented platforms and Google Pay offering Android, iOS, and web support. For Stellar rather than Bitcoin, Solar Wallet is a free alternative whose code is published under the GPL license for public auditing. Browse more options in Digital Wallet Apps.

Verdict

Choose Armory if you want a free Bitcoin wallet built for offline key storage, online watching-only access, and a clear sign-offline, broadcast-online transaction path. Its control and multi-signature tools are compelling for users willing to manage their own security; look elsewhere if you want a broader currency remit, less demanding key handling, or a wallet experience centered on everyday payments.
