Agent Passport vs PromptMan

Agent Passport and PromptMan are both inference engines & infra tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Agent Passport

Agent Passport is an open-source authorization layer that sits between your agents and the actions they take. You issue a scoped passport — specific permissions, a spend cap, a time window — then every action checks against it before executing. Denied calls are logged alongside allowed ones, so you have a record either way. Delegation chains shrink permissions as they pass down to sub-agents; a child passport cannot exceed what the parent granted. Revocation cascades instantly across the whole chain, so you're not hunting down API keys across six services.

PromptMan

The core workflow is fast: hit ⌘⇧O from any editor, browser, or terminal, pick a prompt, copy it into ChatGPT or Claude, done. Templates support placeholders for variables like tone or audience, so the same prompt structure produces consistent output without retyping the scaffolding each time. Prompt versioning lets you save iterations and discard the ones that underperform. The free tier caps you at 10 saved prompts — enough to test, not enough for a working library. Cross-device sync runs through Supabase; iOS support is listed as coming soon.

Pros	Scoped permissions per agent per task, so a booking bot that needs calendar access cannot also charge a payment method — even if the underlying account credentials would allow it. Server-side spend tracking with hard caps, which means agents cannot silently drain API budgets between monitoring checks — the deny fires at the limit, not after the bill arrives. Instant cascade revocation across delegation chains, so cutting off a parent passport stops all child agents immediately without rotating keys across every downstream integration. Every authorize() call is logged whether allowed or denied, so when an auditor asks what your agent attempted at 14:23:08, you have a signed record — not a gap. Purpose-built packages for LangChain, CrewAI, Express, Fastify, and MCP, so wrapping existing agent tools does not require rewriting call patterns from scratch.	Global shortcut (⌘⇧O) opens the prompt library from any Mac app without switching windows, so context-switching tax drops to under three seconds per prompt retrieval. Variable placeholder templates turn a single prompt structure into a reusable framework for different audiences or tones, which means you stop rewriting scaffolding from scratch and get consistent AI output across sessions. Prompt versioning lets you save and compare iterations side by side, so the best-performing variant survives instead of getting overwritten the next time you tweak the wording. Fuzzy search with tag and category filtering finds the right prompt across a large library in seconds, so the 'I know I wrote that prompt somewhere' problem stops costing you minutes per day. Supabase-backed cloud sync keeps prompts backed up without manual export, so a machine wipe does not also wipe your prompt library.
Cons	The audit store is SQLite. A single-file database works for a single server and moderate throughput — teams running multiple agent instances or high-frequency authorize() calls will hit write contention and need to either replace the persistence layer or front it with a queue, at which point they are maintaining infrastructure the tool does not provide. There is no managed cloud option; every component is self-hosted. Teams that need a SOC 2-audited, access-controlled audit log with role-based visibility into the dashboard will build that controls layer themselves — and teams whose security policy prohibits self-managed audit storage will move to a vendor that offers it. Delegation only constrains permissions downward — it does not add them. If your agent graph needs a sub-agent to acquire permissions the parent was not issued, you reissue from the top, which means any workflow that dynamically expands scope mid-run requires a round-trip to the issuing authority rather than a local escalation path.	The free tier caps storage at 10 saved prompts — a working daily library for a writer or marketer exceeds that ceiling within days, at which point continued use requires a paid upgrade or the tool becomes a demo. There is no API, no programmatic access, and no direct injection into AI tools — every prompt goes through manual copy-paste, which means teams building automated pipelines or wanting prompts to fire without human intervention switch to a dedicated prompt management platform with API support. Team collaboration is limited to the vendor's description of the library as something that 'can be shared or referenced' — there are no shared workspaces, permission tiers, or role-based access controls, so marketing or engineering teams standardizing AI inputs across more than one person are working around the tool's architecture rather than with it. macOS 13+ exclusivity and the absence of a web interface or Windows support means any team member not on a recent Mac cannot access the library at all, forcing mixed-platform teams to maintain a parallel prompt repository elsewhere.

Bottom line

Agent Passport is free while PromptMan is paid; Agent Passport is open source; only Agent Passport exposes a public API. Choose based on which difference matters most for your workflow.
