Ideal use cases:
- •Teams or individuals who need access 290+ ai models via single api
- •Teams or individuals who need provider pricing passthrough (no markup)
- •Teams or individuals who need bring your own api keys (byok)
- •Teams or individuals who need model comparison and benchmarking
- •Anyone focused on llm api workflows
- •Anyone focused on model gateway workflows
Best for: Preloop
Preloop is an Apache-2.0 licensed control plane for AI agents, aimed at the governance problem that appears the moment more than one agent is running in an organisation: nobody can see what tools they can reach, what they are spending, or who approved anything. It bundles six capabilities into one self-hostable platform — an MCP firewall that defines allow, deny and require-approval rules on tool access; an AI model gateway that attributes cost and enforces per-agent budgets; policy-as-code written in YAML with CEL expressions; human-in-the-loop approvals delivered to mobile, watch, Slack, Mattermost or a webhook; runtime session observability; and an audit trail. Onboarding is deliberately frictionless: `preloop agents discover` finds compatible agent configurations already on the machine and transparently rewrites them so tool calls route through the MCP firewall and model traffic through the gateway, with no SDK changes and no agent code changes. The named runtimes it rewrites include Claude Code, Codex CLI, Cursor, Gemini CLI, Hermes, OpenClaw, OpenCode and Windsurf. The vendor positions Preloop explicitly as an open-source alternative to AWS Bedrock AgentCore and as a way to build EU AI Act readiness evidence, with dedicated guidance published for that use case. Because the full control plane is Apache 2.0 and self-hostable, the paid tiers sell hosting, team governance and conditional-approval sophistication rather than the core capability.
Ideal use cases:
- •Teams or individuals who need mcp firewall with allow, deny and require-approval rules on tool access
- •Teams or individuals who need ai model gateway with per-agent budgets and cost attribution
- •Teams or individuals who need policy-as-code in yaml with cel expressions
- •Teams or individuals who need human approvals on mobile, watch, slack, mattermost or webhook
- •Anyone focused on mcp workflows
- •Anyone focused on agent-governance workflows
