Best for: Developers and platform teams that need secure public URLs, ingress, and traffic policy for local dev, webhooks, and production APIs.
- 03
AppVeyor
AppVeyor is a hosted CI/CD service for Windows, Linux, and macOS that connects to source control and runs builds on cloud VMs with admin access. It supports multi-stage deployments, self-hosted build agents, and parallel jobs for teams shipping cross-platform software.
Best for: Developers and release teams that need Windows-friendly CI/CD alongside Linux and macOS build agents.
- 04
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.
