Revdoku
Revdoku gives AI agents dedicated email inboxes with cloud storage, attachment handling, and REST, CLI, or MCP access. Teams provision mailboxes, connect AI workflows, and manage files generated by agents or APIs under EU hosting options.
Best for: Developers building AI agents that need real email addresses and file storage integrations.
- 03
Freestyle
Freestyle provides full Linux VMs purpose-built for long-running AI agents with millisecond startup, live cloning, pause/resume, nested Docker, and custom networking. Developers use the VMs for coding agents, browser automation, and containerized workloads.
Best for: Teams building autonomous agents that need persistent Linux environments, previews, and Docker inside the VM.
- 04
Doppio
Doppio is a managed HTML-to-PDF and screenshot API that renders documents without self-hosting Puppeteer. It offers Chromium-based rendering, direct S3 upload, webhooks, templates, and EU-hosted infrastructure for production PDF and PNG generation at scale.
Best for: SaaS teams and agencies that need reliable PDF or screenshot generation from HTML templates in production.
- 05
Mem0
Mem0 provides persistent memory infrastructure for AI agents and applications so context survives across sessions, users, and agents. The platform offers hosted plans with SDK integration plus open-source options for developers building production agents that need durable recall.
Best for: Agent builders and app teams that need hosted memory layers with defined add and retrieval quotas.
- 06
Letta
Letta is an AI research lab and product company building stateful agents whose memory and capabilities evolve over time, originating from MemGPT research. It ships Letta Agent software, a CLI, and cloud plans for individuals, teams, and API developers.
