Mosaic is an all-in-one application infrastructure platform for AI engineers and “vibe engineers.” Its goal is to bring the database, object storage, authentication, realtime messaging, Git hosting, deployment, domain SSL, and email capabilities that most new projects need into a single dashboard, one API key, and one bill. In positioning, it is similar to bundling the capabilities of Supabase, Neon, S3, Auth0, Pusher, deployment platforms, and similar services into a unified backend foundation.
According to the available information, each Mosaic project gets its own PostgreSQL 17 database, with support for pgvector, full-text search, extensions, and SQL over HTTP. Its object storage is S3-compatible and supports presigned upload and download URLs. Authentication supports magic links, email/password login, Argon2 hashing, and JWT sessions. Realtime features include WebSocket subscriptions to row-level changes, while Redis supports KV, counters, lists, queues, and pub/sub. For deployment, Mosaic supports deploying from Git, covers Node, Python, Go, Rust, PHP, Ruby, Java, and static sites, and can automatically detect the project type. It also includes custom domains, automatic Let's Encrypt SSL, domain email, DKIM/SPF/DMARC, IMAP, and SMTP.
Mosaic emphasizes that AI Agents can operate the platform directly, such as creating projects, provisioning databases, and retrieving connection strings. Its unified API is located under api.mosaic.site/v1/project/..., uses X-API-Key authentication, and provides Swagger, ReDoc, an API Reference, and an agent-facing skill.md. There is also an npm installation method for @mosaicsite/claude-skill. The documentation covers Getting Started, authentication, databases, storage, Realtime Redis, domains, email, deployment, and more, with a fairly complete structure.
Pricing is straightforward: a 7-day free trial, up to 3 projects, including PostgreSQL, Git hosting, and automatic deployment, but a credit card is required. The All In plan costs $10/month and supports unlimited projects, a total of 1TB storage, custom domains, no auto-suspend, and priority support. Team seats cost an additional $5/seat. The text does not disclose details on overage usage, compute resource specs, backups, data regions, or SLA terms, although the homepage claims a 99.99% Uptime SLA.
The main advantages are broad feature coverage and a unified onboarding path, making it especially suitable for indie developers, small teams, AI coding agent-driven prototypes, and multi-project management. The drawbacks are limited information on whether it is open source or closed source, self-hosting, compliance, data residency, enterprise support, and ecosystem case studies, so production use needs further evaluation. Accessibility from China is not disclosed, and the domain, API, and payments all require hands-on testing. If network access or payments are restricted, a combination of domestic cloud databases, object storage, function/container services, and authentication services may be an alternative.
