Offline Software for Work That Cannot Wait for a Connection

An offline application is installed, not visited. Its code runs on your processor, it reads and writes files on your own disk, and it does not need a remote server to open a document, record a sale or run a workflow. Some offline applications also use the internet for particular tasks, such as sending an email or calling a web service, but the core work does not stop when the connection does.

That is different from a web application, which lives on a provider's servers and is shown to you through a browser. When the connection or the provider has a problem, a web application usually cannot open your work at all. Our guide on what happens to cloud software when the internet goes down looks at this in more detail.

The reasons are practical rather than ideological. A shop needs its till to keep selling during a broadband fault. A consultant needs to finish a report on a train. A field team needs to collect survey answers where there is no signal. A studio needs to edit large video files without uploading them first.

• Internet dependency: work continues through outages, travel and poor coverage.
• Business continuity: a fault at a provider does not lock you out of your own records.
• Privacy: files are processed where they are stored instead of on someone else's servers.
• Data access: your documents stay readable as ordinary files, even without the vendor's service.
• Speed with large files: audio, video and big workbooks are handled on local storage.

Local processing matters most where files are large, sensitive or needed at a fixed moment. Retail is the clearest case: a point of sale that stops when the internet stops costs sales immediately. Media work is another, because footage and multitrack audio are slow to move. Confidential documents, such as contracts and client reports, are a third, because editing them locally avoids handing them to an online service.

Offline software is not the right answer to everything. Real-time co-editing of one document by many people, or services that exist to publish online, naturally depend on a connection. Aevornix applications are built for the work that should not.

Each page below covers one kind of offline software in depth, with the Aevornix application that fits and its current limits.

• Offline office suite for documents, spreadsheets, presentations, PDF and planning.
• Offline PDF editor for reading and editing PDFs without uploading them.
• POS software that works offline for shops that must keep selling.
• Offline inventory management for stock, purchasing and counts.
• Offline workflow automation for files, scripts and Windows applications.
• Offline audio editor for recording, editing and mixing.
• Offline video editor for cutting and delivering video.
• Offline email client for reading and searching mail you already have.

Aevornix applications are sold as one-time licences rather than subscriptions. A licence is permanent for the major version you buy and includes maintenance updates for that version. Home, Student, Professional and Business tiers set how many people and devices it covers, and whether commercial use is permitted. Prices are shown on each product page; how Aevornix licences work explains the tiers.

When comparing offline software, check what actually works without a connection rather than what the label says. Ask whether the program can open existing files, whether it needs an online sign-in to start, where backups go, and what stops working when you are offline. For Aevornix products those answers are on each product page, including the features that are not built yet.

If you are replacing a subscription service, the software subscription cost calculator shows what that service costs over several years, and our comparisons set the products side by side.
