Jami

Overview

Jami combines private messaging, calls and conferencing in a free, peer-to-peer communication app. It is a strong fit for people who want encrypted conversations without a relay server or personal details at account creation. Its breadth is a draw, but the experience depends on the client you use.

Key features

Messaging includes group chats and recorded audio and video messages, alongside audio and video calls. Video conferences and rendezvous points do not rely on third-party hosting, while screen sharing, media streaming and file sharing add options for group collaboration. That makes Jami more than a private chat app, though people choosing it for calls should confirm that the features they need are supported on their device.

Jami says it operates entirely peer to peer, without a server relaying data between users. Communications are end-to-end encrypted by default, with perfect forward secrecy, and comply with the X.509 standard. Users can link multiple devices to one account, and creating an account does not require personal information. Those choices will appeal to people who prioritize privacy, although peer-to-peer operation may not suit every communication setup.

Jami can also serve as a regular SIP client. Its extensions include green screen, watermark, auto answer, local AI transcription, audio filters and video segmentation. Extensions are unavailable on iOS, and features vary by client. If a particular extension is central to your workflow, Jami is a less certain choice on iPhone or iPad; check the relevant client before relying on it.

Jami provides an OpenClaw channel plugin, with bot accounts and API access supported on desktop Linux, macOS and Windows. The project also documents a web version accessible through a browser. That client-specific spread matters: a feature found on desktop may not carry over to mobile or web.

Pricing

Jami costs nothing, with no free trial because the software is free. The Jami plan is free/libre communication software, with no stated caps on file size, speed, bandwidth, features, accounts or storage. It suits individuals and groups who want to use the core service without a paid tier, and there is no cheaper plan with reduced limits to weigh against it.

The trade-off is not price but client coverage: feature availability varies, and iOS users cannot use extensions. Jami directs questions to its forum and provides [email protected] as a contact address.

Platforms

Jami is available for Android, iOS, Linux, macOS, web and Windows, with API and extension support also listed. Web access is through a browser. The API and bot-account support is specifically for desktop Linux, macOS and Windows; extension availability also varies by client.

Who it's for

Choose Jami if you want messaging, calls, conferences and sharing in one free service, particularly if server-free peer-to-peer communication and account creation without personal information matter to you. It is less suitable if you need every feature to work consistently across clients, or if you rely on extensions from an iOS device.

Pros and cons

• Pros: Free/libre software covers messaging, calls, conferencing and file sharing without stated account, storage or bandwidth caps.
• Pros: Peer-to-peer communication, default end-to-end encryption and account creation without personal information support a privacy-focused setup.
• Pros: SIP support and desktop bot and API access extend its use beyond ordinary chat.
• Cons: Features differ by client, so users may not get the same capabilities across devices.
• Cons: Extensions are unavailable on iOS, excluding iPhone and iPad users from tools such as local AI transcription and video segmentation.

Verdict

Jami is a compelling choice for people who want a free, privacy-oriented suite of messaging, calls and conferencing without a relay server or personal details at sign-up. Its strongest reason to choose it is that combination of breadth and peer-to-peer design at no stated usage caps. Look elsewhere if consistent feature coverage across clients is essential, especially if you need extensions on iOS.
