Comparison
Jentic One vs Nango
Jentic One is a self-hosted control plane for the API calls your AI agents make, compared with Nango, a platform for building and syncing product integrations.
At a glance
Jentic One vs Nango, feature by feature
A side-by-side look at how each tool handles the things that matter when an AI agent calls real APIs.
| Feature | Jentic One | Nango |
|---|---|---|
| Primary job | Govern the agent as the caller of any API. | Connect your product to third-party APIs, with managed OAuth and data sync. |
| Hosting model | Self-hosted by default, or run for you with Jentic One Enterprise. | Cloud by default. Self-host and BYOC are Enterprise-only. |
| Where credentials live | On your own instance. The agent never sees a key; the broker injects it at call time. | On Nango’s infrastructure by default. On yours with self-host or BYOC (Enterprise). |
| Governance | Per-agent, per-operation rules. Writes denied by default. | Allow and deny per tool (the action functions you build). |
| Audit | Append-only log of every allowed and denied call, on your own instance. | Agent calls appear in its logs. The account audit trail is Enterprise-only. |
| Integrations | 10,000+ APIs, plus any private or niche API via its OpenAPI spec. | 1,000+ APIs and 7,000+ connector templates. |
| Open source | Yes, Apache-2.0 (OSI open source), including the broker that holds credentials. | Elastic License 2.0 (source-available, not OSI open source). |
| Data sync | Not offered. Jentic One brokers agent calls, it does not sync product data. | Yes, background data sync and unified data models. |
Head to head
Jentic One vs Nango, honestly
Nango is a strong, mature integrations platform with a huge connector catalog, and it now serves tools to agents too. Jentic One is a younger, purpose-built broker for governing what an agent is allowed to call. Here is where each is genuinely stronger.
Jentic One
Self-hosted, open-source agent broker that governs the agent as the caller.
Strengths
- Self-hosted by default, so credentials and the audit log stay on your own instance and never leave it.
- Per-agent, per-operation rules, with writes denied by default. Governance down to the individual API operation.
- Append-only audit of every allowed and denied agent call, standard on every instance, not a paid add-on.
- A directory of 10,000+ APIs, and you can import any private or niche API by its OpenAPI spec.
- Truly open source under Apache-2.0. Audit it, fork it, run it with no usage-licence restrictions.
- Credentials injected at call time, so the agent only ever receives the result of an allowed call.
Trade-offs
- You run the instance yourself on the open-source tier, though Jentic One Enterprise can run it for you.
- Public beta, younger and less battle-tested than Nango.
- No managed OAuth across hundreds of providers out of the box.
- Does not do product data sync or background syncing. That is not what it is for.
Nango
Mature integrations platform: managed OAuth, data sync and 1,000+ connectors for your product.
Strengths
- Large, mature catalog of 1,000+ APIs and 7,000+ connector templates out of the box.
- Best-in-class managed OAuth and token refresh across hundreds of providers.
- Real data sync and unified data models, which Jentic One does not do.
- Code-owned integration logic as TypeScript functions, with CI/CD and isolated environments.
- Runs on Nango Cloud, BYOC, or self-hosted, with a large community (12.5k GitHub stars).
Trade-offs
- Licensed under Elastic License 2.0: source-available, not OSI open source, and you may not run it as a hosted service.
- Self-hosting, BYOC and the audit trail are Enterprise-only, and the audit trail covers account changes, not agent calls.
- Cloud-first, so on the default tier your third-party tokens live on Nango’s infrastructure.
- Built product-integration-first, so governing the agent as a caller is an additive layer.
Bottom line: Choose Nango to connect your product to many third-party APIs with managed OAuth and data sync. Choose Jentic One to govern, and audit, exactly what an AI agent is allowed to call, on infrastructure you own.

Where they differ
A self-hosted broker for agent API calls, not an integrations platform
Nango focuses on connecting your product to third-party APIs: managed OAuth and data sync for the integrations your software ships. Jentic One focuses on the agent as the caller, giving you per-operation control and an append-only audit trail over every API call an agent makes, on infrastructure you run yourself.
Self-hosted by design
You run Jentic One on your own infrastructure, on-prem or in your own cloud. Credentials and the audit log live only on your instance and never leave it.
Credentials injected at execution
You store a credential once. The broker injects it at call time, so the agent receives only the result of an allowed call and never sees the key itself.
Per-agent, per-operation rules
You write rules that bound each agent to the operations it needs, and nothing else. How granular this gets depends on the API. Writes are never allowed by default.
Append-only audit on your instance
Every call an agent makes is logged, allowed or denied, in an append-only audit trail on your own instance. The broker is the only path to any API, so no call bypasses the log.
FAQ
Jentic One vs Nango
They overlap only partly. Nango is an integrations platform for syncing data and managing OAuth between your product and third-party APIs. Jentic One is a self-hosted agent broker that governs the API calls your AI agents make, with per-agent rules, credential injection at execution, and an append-only audit log on your own instance.
