Nango

Nango provides infrastructure for building, running and maintaining integrations between products or AI agents and external APIs. Its features cover authentication, agent tools, webhooks, triggers and managed incremental data syncs, with a catalog of more than 1,000 supported APIs. Integrations are built as code, with local development, CI/CD and multiple environments in the workflow. Authentication methods include OAuth 2.0, OAuth 1.0a, API keys, JWT, Basic auth and MCP auth. Nango manages token refresh, encrypts credentials in transit and at rest, and provides tenant isolation. Runtime features include resumable executions, retries, rate-limit handling, logs, metrics and alerts. The Free plan has monthly hard caps of 10 connections, 10 compute hours and 10GB data transfer. Pay-as-you-go is $50 a month and includes $50 in monthly credits, with additional listed rates of $0.29 per connection, $0.72 per compute hour and $0.5 per GB of data transfer. Self-hosting and custom connectors are supported.

Nango combines a broad API catalog with code-based development and runtime features for operating integrations. Check the Free plan's monthly caps and the pay-as-you-go rates against expected use.

Nango is aimed at developers building integrations for products or AI agents who want code-based workflows and managed authentication or sync infrastructure. Its Free plan offers a bounded monthly allowance, while self-hosting is available.

Nango is integration infrastructure for teams connecting products or AI agents to external APIs. It is best suited to developers who want integration logic in code while outsourcing authentication and runtime operations. The main trade-off is between its strong operational toolkit and the hard ceilings on the free tier.

Overview

Nango combines a catalog of more than 1,000 APIs with infrastructure for building, running, and maintaining connections. It supports common integration patterns such as authentication, AI-agent tools, webhooks, triggers, and managed incremental synchronization. This makes it a practical foundation for software companies that need integrations to remain reliable as APIs change, rather than a simple point-to-point automation service.

The code-first approach preserves control over business logic and deployment workflows. In return, teams remain responsible for writing and maintaining that logic. Nango is therefore a stronger fit for engineering-led products than for nontechnical users seeking a visual workflow designer.

Key features

Prebuilt tooling covers authorization, pagination, rate limits, and webhooks across the API catalog, reducing repetitive connector work. Supported authentication methods include OAuth 2.0, OAuth 1.0a, API keys, JWT, Basic auth, and MCP auth. Nango handles token refresh, encrypts credentials both at rest and in transit, and provides tenant isolation, which is important when one product serves many customer accounts.

Integrations are built as code, with local development, CI/CD, and multiple environments supported. Custom connectors and reusable workflows extend the catalog when a required service is not covered. Runtime safeguards include resumable executions, retries, rate-limit handling, logs, metrics, and alerts. Those features are valuable for long-running synchronizations and production support, although they do not remove the need for engineers to monitor and refine connector behavior.

The authentication interface can be branded or customized. Bringing your own OAuth app enables a fully white-label experience, a meaningful advantage for SaaS vendors that want customers to see their own brand during authorization.

Nango lists SOC 2 Type II certification, and its authentication materials cite SOC 2, GDPR, and HIPAA compliance. There is no EU-hosted cloud currently; Enterprise customers can instead use BYOC instances in AWS, GCP, or Azure regions. That option helps with regional requirements but places deployment decisions in the enterprise tier.

Pricing

The Free plan is suitable for prototypes and small workloads, but its monthly limits are hard caps that reset each month. Ten connections, 10 compute hours, and 10GB of transfer can be consumed quickly by a product with several tenants or frequent syncs.

Pay-as-you-go removes those fixed free-tier ceilings in favor of usage billing and includes $50 in monthly credits. It fits teams moving toward production that want a predictable starting commitment while paying for additional connections, compute, and transfer as usage grows. Calculate expected consumption carefully: high-volume synchronization can exhaust the credits and add metered charges.

Enterprise is the route for organizations requiring self-hosting, contractual terms, service-level agreements, or committed-volume discounts. Its custom pricing means smaller teams should first determine whether the metered plan covers their actual load.

Free and pay-as-you-go customers receive in-app chat support from Nango engineers. Growth add-on and Enterprise customers receive a private Slack Connect channel, which is more appropriate for operationally critical deployments.

Platforms

Nango is offered through API, web, and self-hosted deployment options. Self-hosting and Enterprise BYOC support are useful when infrastructure control or regional placement outweighs the convenience of a fully managed cloud service.

Who it's for

Choose Nango if your team builds a product with many customer-facing integrations, needs several authentication standards, or wants reliable sync and webhook execution without implementing token management and retry systems from scratch. Code ownership, CI/CD support, custom connectors, and white-label authentication particularly favor SaaS engineering teams and AI products.

It is less suitable for nontechnical operators who expect a visual builder, for very small projects that will exceed the Free plan quickly, or for organizations that require an EU-hosted managed cloud without adopting BYOC.

Pros and cons

Pros

• More than 1,000 APIs and prebuilt handling for authorization, pagination, rate limits, and webhooks reduce recurring connector plumbing.
• Broad authentication support, token refresh, encryption, and tenant isolation address core multi-tenant security concerns.
• Resumable runs, retries, metrics, logs, and alerts provide operational protection for ongoing synchronization.
• Code workflows, custom connectors, reusable workflows, and white-label OAuth support give product teams control over implementation and branding.
• Self-hosting and BYOC options help enterprises meet infrastructure and contractual requirements.

Cons

• The Free plan is constrained by hard monthly caps of 10 connections, 10 compute hours, and 10GB of transfer.
• Usage beyond the included $50 monthly credits is metered, so high-volume workloads require careful forecasting.
• No EU-hosted cloud is currently offered; regional control requires Enterprise BYOC.
• Code-first development favors engineers and does not provide a visual workflow-building experience.

Alternatives

Browse API Integration Platforms or Integration Platform as a Service Software for a wider field.

• Knit is a better fit when you need Android and iOS coverage and a $499 a month Start Up plan with 100K API calls and unlimited data usage.
• TransportAPI suits modest request volumes, with a free forever plan allowing 30 API hits per day.
• Celigo is preferable when a visual, flow-oriented service with defined endpoint and flow limits matches your operating model.
• Workato Agent Studio is aimed at agentic capabilities, with a free plan including 50,000 one-time credits and a $75 a month Pro plan.
• Apache Camel is the no-cost, Apache License 2.0 choice for teams willing to run and maintain an open-source integration framework themselves.
• Google Cloud Application Integration fits teams already using Google Cloud that can work within its free-tier execution and data-processing allowances.
• Pipedream is worth choosing for its free development plan, 3,000+ connectors, and 10,000+ prebuilt tools and triggers.
• Superfeedr is a focused option for real-time feeds and PubSubHubbub-compliant distribution.

Verdict

Nango is a strong choice for engineering teams building a multi-tenant product that needs broad API coverage, code-controlled integrations, and dependable runtime operations. Choose it for managed authentication, synchronization safeguards, and deployment flexibility. Look elsewhere if a visual builder, an EU-hosted cloud, or simpler fixed pricing matters more than developer control.
