Tau pricing
Pricing model: Freemium
Taubyte is completely free and open source under the MIT License. There are no paid plans - you can self-host the entire platform at no cost. The pricing page is no longer active, confirming the shift to a fully open source model. Users download Tau (core component) and Dream (local development tool) freely via npm (@taubyte/tau, @taubyte/dream), one-line installers (curl get.tau.link/cli | sh), or manual binary downloads for macOS, Linux, and Windows. No vendor lock-in means you only pay for your own hardware or cloud provider infrastructure.
Tau pros
- Open source under MIT License with no cost to self-host
- Git-native infrastructure with branch-based environments
- Local development exactly matches production environment
- WebAssembly functions spawn in milliseconds with near-zero cold starts
- No Kubernetes dependency - built from ground up without baggage
- Single binary deployment with no external dependencies
- Automatic service discovery eliminates complex setup
- P2P architecture with automatic node and service discovery
- Content-addressed storage with automatic deduplication
- Zero-configuration HTTPS/TLS with automatic certificate management via ACME
- Deploy on your own hardware or any cloud/bare-metal provider
- No vendor lock-in - full control over infrastructure
- Dream provides local cloud environment with MCP server for AI agents
- Distributed architecture scales horizontally and vertically automatically
- NAT traversal and circuit relay allow non-public nodes to participate
- Customizable Web Console plus powerful CLI for Go-based automation
- Plugin system called orbit for extending platform capabilities
Tau cons
- Relatively new platform launched in 2022 with smaller community
- Documentation still incomplete for some features like Dream E2E testing
- Containers and VMs for computing not yet supported (only WebAssembly)
- Desktop application for Dream still coming soon
- Requires own hardware or cloud provider - no managed hosting offered
- Smaller ecosystem compared to established platforms like Vercel or AWS
- Learning curve for distributed P2P architecture concepts
- Limited third-party integrations compared to mature platforms
- Self-hosting requires operational expertise to maintain
Frequently asked questions about Tau
What is Taubyte?
Taubyte is an open-source, Git-native cloud computing platform and serverless operating system that enables developers to build and maintain highly scalable cloud infrastructure with minimal configuration. It serves as an alternative to Vercel, Netlify, Cloudflare, and AWS services, with the goal of making Local Development equal to Global Production.
Is Taubyte free to use?
Yes, Taubyte is free and open source under the MIT License. You can self-host the entire platform at no cost. There are no paid plans - the pricing page is no longer active, confirming the shift to a fully open source model.
What cloud capabilities does Taubyte provide?
Taubyte provides Serverless Functions (WebAssembly with automatic scaling), Website Hosting (static site hosting with global distribution), Key/Value Databases (distributed storage with automatic replication), Object Storage (file storage with content addressing), Messaging Pub/Sub (real-time messaging with WebSocket support), and CI/CD (Git-native deployment pipelines). Work is ongoing to add unikernels and containers.
How does Git-native infrastructure work?
Taubyte uses Git as the only mechanism to alter infrastructure, eliminating API-based configuration. Nodes tune to specific Git branches (default: main/master), and the TNS service uses commit IDs to version application entries. This provides branch-based environments, commit-based versioning, and distributed configuration stored in Git repositories synchronized across nodes.
What is Dream and how do I use it?
Dream is a tool that runs a cloud locally for development and testing. It comes with an MCP server for AI agents and a DNS server for name resolution. Install via npm with 'npm install -g @taubyte/dream' and create a local cloud with 'dream new multiverse'. It enables comprehensive end-to-end testing with libdream, ensuring seamless functionality upon deployment.
How do I install Tau?
Install Tau using the one-line installer: 'curl https://get.tau.link/tau | sh -s'. Alternatively, use npm with 'npm i @taubyte/tau' or download binaries manually for macOS, Linux, or Windows. After installation, configure with 'tau config generate -n mycloud.xyz -s compute --ip A.B.C.D --dv --swarm' and start with 'tau start -s compute'.
Does Taubyte use Kubernetes?
No, Taubyte is built from the ground up and does not depend on Kubernetes. The developers wanted something that doesn't carry the baggage of traditional cloud platforms, resulting in a single binary with no external dependencies except standard system libraries.
What programming languages are supported for serverless functions?
Taubyte executes serverless functions using WebAssembly, which provides cross-platform portability. The CLI supports creating functions with Go or Rust using templates like 'tau new function --lang Go|Rust --template ping_pong'. WASM modules run consistently across different architectures with sandboxed execution.
How does content-addressed storage work?
Instead of location-based addressing, Taubyte uses content-addressing where files are identified by their cryptographic hash (CID). Content is chunked and stored in a DAG with automatic deduplication. Content can be downloaded from multiple peers in parallel, verified since the CID is its hash, and the cloud automatically dedicates more peers to distribution when content is in demand.
Can I deploy Taubyte on my own infrastructure?
Yes, Taubyte is designed for self-hosting on your own hardware, any cloud platform, or bare-metal provider. Use Spore-Drive (recommended) to provision large numbers of nodes, or use the script installer. Single binary deployment requires minimal configuration with auto-discovery built-in. You need at least one bootstrap peer for network entry and an FQDN for cloud identification.
