Nango

Nango is integration infrastructure for connecting products and AI agents to external APIs while keeping integration logic in code. It is aimed at engineering teams that need authentication, synchronization, and runtime operations managed around their own connectors. The main question is whether its developer control and operational safeguards justify its usage charges and deployment constraints.

Overview

Nango combines a catalog of more than 1,000 supported APIs with infrastructure for building and maintaining connections. Its patterns cover authentication, AI-agent tools, webhooks, triggers, and managed incremental data syncs. That makes it more suitable for a product with integrations that must keep running and recover from failures than for a one-off data transfer.

The code-based workflow preserves control of business logic and supports local development, CI/CD, and multiple environments. The trade-off is that developers still write and maintain the integration behavior; this is not a visual, no-code builder. Self-hosting and custom connectors broaden deployment and coverage options.

Key features

Prebuilt tooling for authorization, pagination, rate limits, and webhooks can remove repetitive connector plumbing across the API catalog. Authentication supports OAuth 2.0, OAuth 1.0a, API keys, JWT, Basic auth, and MCP auth. Nango manages token refresh, encrypts credentials at rest and in transit, and isolates tenants, useful safeguards for software serving multiple customer accounts.

Runtime features include resumable executions, retries, rate-limit handling, logs, metrics, and alerts. These controls help teams operate integrations through transient API failures and ongoing changes rather than treating them as fragile scripts. Reusable workflows and webhook triggers support recurring integration patterns, while custom connectors cover APIs outside the catalog.

The authentication interface can be branded or customized. Bringing your own OAuth application enables a fully white-label sign-in experience, which matters when end users should see your product rather than an infrastructure provider.

Nango lists SOC 2 Type II certification, and its authentication materials cite SOC 2, GDPR, and HIPAA compliance. Support is in-app chat for Free and pay-as-you-go customers; Growth add-on and Enterprise customers receive a private Slack Connect channel with Nango engineers.

Pricing

Free

The Free plan costs nothing and includes 10 connections, 10 compute hours per month, and 10GB of data transfer per month. These are hard caps that reset monthly, so it can work for prototypes or small integration footprints but gives little room for a growing production workload.

Pay-as-you-go

Pay-as-you-go costs $50 a month, billed at $50 /mo, and includes $50 in monthly credits. Usage beyond the included allowance is charged at $0.29 per connection, $0.72 per compute hour, and $0.5 per GB of data transfer. This is the practical step up for teams whose usage is variable and who need more capacity than the free ceilings, though costs rise with connection count, runtime, and data volume.

Enterprise

Enterprise has custom pricing, with discounts for commitments, self-hosting, an MSA, and an SLA. It is the relevant tier for organizations that need contractual terms or want to run an Enterprise BYOC instance.

Platforms

Nango is offered through web and API access, with self-hosted deployment supported. Nango says it does not currently provide an EU-hosted cloud. Enterprise customers can use BYOC instances in AWS, GCP, or Azure regions, which is the route for teams with stricter regional hosting requirements.

Who it's for

Nango fits developers building SaaS products, internal platforms, or AI agents that need many third-party connections and dependable synchronization. It is particularly compelling when code ownership, white-label authentication, tenant isolation, and operational visibility matter. Small experiments can start free, but the hard monthly caps make the free tier unsuitable for sustained, high-volume production use. Teams seeking a visual integration designer, or a standard EU-hosted cloud without an Enterprise arrangement, should look elsewhere.

Pros and cons

• Pros: More than 1,000 APIs and tooling for authorization, pagination, rate limits, and webhooks reduce common connector work.
• Pros: Broad authentication support, token refresh, encryption, and tenant isolation address recurring security and credential-management tasks.
• Pros: Retries, resumable executions, logs, metrics, alerts, and managed incremental syncs support production operations.
• Pros: Code workflows, custom connectors, self-hosting, and white-label OAuth provide control over implementation and presentation.
• Cons: The Free plan is hard-capped at 10 connections, 10 compute hours, and 10GB of monthly transfer.
• Cons: Usage-based charges can increase as connections, compute, and transferred data grow beyond the $50 monthly credit.
• Cons: There is no EU-hosted cloud; regional control requires Enterprise BYOC deployment.

Alternatives

Choose Knit instead if you need Android and iOS access alongside web and API platforms, with a Start Up plan at $499 a month that includes 100K API calls and unlimited data usage.

Apache Camel is the better choice for a free, open-source, self-hosted framework under the Apache License 2.0.

Pick Apache NiFi for a free Apache-licensed platform spanning desktop operating systems, web, API, and self-hosted deployment.

TransportAPI suits a narrower API use case when a free forever plan with 30 API hits per day is sufficient.

Choose Windmill if a free and open-source platform with self-hosting, three workspaces, and up to 50 users better matches your operating model.

Celigo is an option for web-based flows, with its free plan limited to two endpoints, one flow, and one production environment.

Pick Workato Agent Studio when agent-focused capabilities and a free allocation of 50,000 one-time credits are the priority; its Pro plan is $75 a month.

Google Cloud Application Integration is worth considering when a cloud billing account and a free tier of up to 400 executions and 20 GiB processed monthly fit your needs.

Verdict

Nango is a strong choice for engineering-led products that want code-owned integrations with managed authentication, resilient execution, and extensive API coverage. Choose it for the operational tooling and white-label control; look elsewhere if the free limits are too restrictive or EU-hosted cloud is a requirement without an Enterprise BYOC deployment.
