Carbide Network

Overview

Carbide Network combines personal file storage, team workspaces and developer tools in a distributed network. It is strongest for people comfortable managing their own encryption keys and accepting that performance depends on independent providers. Losing a key means Carbide cannot restore the data.

Key features

Encrypted files and configurable copies

Files are encrypted on the user’s device with AES-256-GCM before encrypted chunks are distributed among independent providers. Users choose from one to 10 copies, a useful level of control over redundancy, though more copies do not turn the service into a guaranteed-availability option: the network is provided without warranties, and performance depends on its participants. Carbide says its zero-knowledge design prevents providers from seeing file contents. Its privacy policy also says it collects public wallet addresses, encrypted sharding metadata and provider performance statistics.

Users manage their own private encryption keys. That arrangement keeps recovery in the user’s hands, but makes careful key preservation essential; anyone who needs provider-assisted recovery should choose another service.

Storage for personal use and teams

Personal storage includes photo and video auto-sync, an encrypted vault, expiring share links and up to 10x redundancy. Those features cover common backup and sharing needs, but the self-managed keys remain a material trade-off for everyday users.

Business workspaces add role-based access, audit logs, retention policies and geographic redundancy across more than 30 regions. These controls make the business offering more suitable for teams than the personal tier, but the lack of a performance warranty matters for organizations that need assured service availability.

Developer and provider tools

Carbide describes its developer storage as API-first and S3-compatible, and provides a Swift SDK for iOS upload, download, encryption and key management. Its versioned discovery API supports provider registration and search, marketplace quotes and health checks. Developers can also self-host the discovery service; settlement uses Solana programs and USDC. This is a more relevant option for builders integrating distributed storage than for users seeking only a conventional sync client.

Providers can install carbide-node through a Homebrew tap, with automatic registration on the Solana registry when configured. Provider earnings are tied to tier and storage supplied, while uptime and redundancy obligations are set by node configuration. Failure to provide data may cost earnings or collateral, so running a node carries operational responsibilities, not just the prospect of income.

Pricing

Carbide presents personal storage at no cost, billed at $0.002/GB, with users paying for storage used. That is a low fixed-cost starting point, but the usage charge means it is not unlimited free storage.

Provider plans are priced as follows:

• Home provider: free, billed $0.002/GB; 95% uptime and estimated earnings of $24/year per TB.
• Professional provider: free, billed $0.004/GB; 99% uptime and estimated earnings of $48/year per TB.
• Enterprise provider: $0.01 a month, billed $0.008/GB; 99.9% uptime and estimated earnings of $96/year per TB.

The higher provider tiers pair higher stated earnings with higher uptime commitments, so they suit operators prepared to meet those requirements; the Home tier has a lower commitment and lower estimated return. The enterprise price is a monthly charge, despite the small amount. Business storage has custom pricing.

Platforms

Carbide is available on macOS, Windows and iOS, with an Android app for managing, uploading and sharing files. Its platform list also includes an API, supporting both client use and developer integration.

Who it's for

Carbide suits individuals who want encrypted backups and sharing with configurable redundancy, teams that need access controls and retention policies, and developers building against an S3-compatible storage interface or discovery API. It is a poor fit for users who cannot reliably safeguard private keys or whose workloads require a performance warranty. Providers should weigh the stated earnings against uptime and data-availability obligations.

Pros and cons

• Pros: Device-side AES-256-GCM encryption and user-selected one-to-10-copy redundancy give users control over privacy and replication.
• Pros: Personal sync and sharing tools sit alongside business controls such as audit logs, retention policies and geographic redundancy across 30+ regions.
• Pros: S3 compatibility, a Swift SDK and a versioned discovery API give developers several integration paths.
• Cons: Lost private keys mean unrecoverable data, placing the burden of key preservation on users.
• Cons: The service has no performance warranty, and availability depends on independent participants.
• Cons: Providers face uptime and redundancy obligations, with possible loss of earnings or collateral if they fail to provide data.

Alternatives

Sia is worth considering for readers who want a freemium, open-source storage project with a free plan. Peergos may suit those who prioritize a fully open-source service, including its server, and reproducible builds. Aleph Cloud (formerly Aleph.im) offers a free tier for static website hosting with IPFS distribution and basic bandwidth, making it a more direct fit for that use. Walrus has a free launch-period plan for readers willing to work within usage limits that may evolve.

Filebase is a freemium alternative with a free tier including 5 GB shared storage, 500 pinned files, 10 GB IPFS egress, free object egress and one bucket. Pinata is another freemium option; its Picnic plan costs $20 a month for one agent, 1TB storage, one gateway plus CDN, 5 million requests and 500GB bandwidth. Stratos is another freemium alternative. Filecoin offers a free plan and a Filecoin Onchain Cloud plan at $2.50 a month, from $2.50 / TB / month with a two-copy minimum.

Verdict

Choose Carbide if you want device-encrypted personal or team storage with configurable copies, or need an S3-compatible path into a distributed provider network. Its key-management model and provider-dependent performance are the reasons to look elsewhere: it is not the right choice if you need account-based recovery or guaranteed availability.
