Nango 替代方案

TL;DR

Nango is no longer just an OAuth proxy. Its current platform spans authentication, credential refresh, proxy calls, custom functions, syncs, webhooks, unified models, tool calling, and a hosted MCP server. A credible “alternative” must therefore replace the layer you actually use—not merely publish more connectors.

Nango 已不再只是 OAuth 代理。当前平台覆盖鉴权、凭证刷新、Proxy、Functions、Sync、Webhook、统一模型、Tool Calling 和托管 MCP Server。真正的替代方案必须替代你正在使用的那一层，而不是只比较连接器数量。

Prerequisites before comparing Nango alternatives比较 Nango 替代方案前的前置条件

A vendor matrix is meaningless until the workload is explicit. Prepare these inputs before requesting demos or estimating migration effort; they turn “integration platform” into a testable architecture decision.

如果工作负载没有说清楚，供应商矩阵就没有意义。在预约 Demo 或估算迁移工作量前先准备以下输入，把“集成平台”变成可测试的架构决策。

Start with the current Nango baseline先建立当前 Nango 的能力基线

An old comparison that treats Nango as “OAuth plus proxy” is now misleading. The official platform describes a broader integration runtime. Evaluate these primitives separately because many teams use only two or three of them.

如果仍把 Nango 写成“OAuth 加 Proxy”，比较就会失真。官方平台已经扩展为更完整的集成运行时。应逐项评估这些能力，因为很多团队实际上只使用其中两三项。

MCP is an interface, not a full Nango replacementMCP 是接口，不是完整的 Nango 替代品

MCP standardizes how a client discovers and calls tools. It does not automatically create OAuth apps, map your product users to vendor accounts, refresh tokens, operate sync jobs, replay webhooks, or define your normalized data contract. Nango can expose action functions through MCP, so the protocol may sit on top of the runtime.

MCP 标准化客户端如何发现和调用工具，但不会自动创建 OAuth App、把产品用户映射到供应商账户、刷新 Token、运行 Sync、重放 Webhook 或定义统一数据契约。Nango 可以通过 MCP 暴露 Action Function，因此协议往往位于运行时之上。

Nango vs Composio: compare product integration to agent sessionsNango vs Composio：产品集成与 Agent Session 的区别

This is the most common comparison, but it becomes useful only after naming the caller. If your product backend owns long-lived customer integrations, syncs records, receives provider webhooks, and runs custom TypeScript integration functions, Nango maps naturally to that architecture. If an agent session needs to select tools for a specific user and initiate authorization inside the conversation, Composio’s session model is closer to the immediate problem.

这是最常见的比较，但必须先明确“谁在调用”。如果产品后端维护长期客户连接、同步记录、接收供应商 Webhook 并运行自定义 TypeScript 集成函数，Nango 更自然；如果 Agent Session 要为特定用户选工具并在会话内发起授权，Composio 的模型更贴近当前任务。

Keep the agent outside the credential boundary让 Agent 留在凭证边界之外

Nango’s official tool-calling pattern resolves a connection for the current product user, then triggers a named action. The model receives a tool schema and result—not the provider token. Keep the integration ID, connection ID, action name, and validated input explicit in your application.

Nango 官方 Tool Calling 模式先解析当前产品用户对应的 Connection，再触发命名 Action。模型只接收工具 Schema 与结果，不接触供应商 Token。Integration ID、Connection ID、Action Name 与已验证输入应在应用侧保持显式。

import { Nango } from '@nangohq/node';

const nango = new Nango({
  secretKey: process.env.NANGO_SECRET_KEY
});

export async function executeCustomerTool({
  integrationId,
  connectionId,
  actionName,
  input
}) {
  assertAllowedTool(integrationId, actionName);
  const validated = validateInput(actionName, input);

  return nango.triggerAction(
    integrationId,
    connectionId,
    actionName,
    validated
  );
}

If you migrate, preserve this boundary behind a small adapter instead of importing provider-specific SDKs throughout the agent code.

迁移时应保留这条边界，用小型 Adapter 隔离平台，而不是让 Agent 代码到处依赖供应商 SDK。

Production requirements that product pages rarely compare产品介绍页很少比较的生产要求

• Tenant identity: prove that every connection, tool call, log, webhook, and record maps to the correct internal user or organization.
• Scope drift: detect when a provider adds, removes, or reinterprets OAuth scopes; re-consent must not silently break the workflow.
• Write safety: require idempotency, confirmation, replay protection, and a stable external object identifier.
• Sync correctness: test cursor loss, duplicate pages, deletes, late updates, backfills, and schema evolution.
• Observability: correlate the agent request, tool name, connection, provider request, retries, cost, and final answer.
• Exitability: know what connection metadata, code, record state, and history can be exported before committing.

• 租户身份：证明每个 Connection、Tool Call、日志、Webhook 和记录都映射到正确的内部用户或组织。
• Scope 漂移：检测供应商新增、删除或重解释 OAuth Scope 的情况，重新授权不能悄悄破坏工作流。
• 写入安全：要求幂等、确认、重放保护和稳定的外部对象 ID。
• 同步正确性：测试 Cursor 丢失、重复分页、删除、延迟更新、回填和 Schema 演进。
• 可观测性：关联 Agent 请求、工具名、Connection、供应商请求、重试、成本与最终答案。
• 可退出性：采购前确认 Connection 元数据、代码、记录状态与历史能导出什么。

Troubleshooting common integration and agent failures常见集成与 Agent 故障排查

Do not collapse every failed tool call into “the provider is down.” Start from the identity and execution boundary, preserve the raw error, and classify the failure before retrying.

不要把所有 Tool Call 失败都归结为“供应商宕机”。应从身份与执行边界开始，保留原始错误，并在重试前完成故障分类。

Self-hosting is a feature matrix, not a checkbox自托管是一张能力矩阵，不是一个勾选项

Nango documents a limited free self-hosted path for Auth and Proxy and a broader Enterprise self-hosted platform. The full architecture introduces multiple Node services plus Postgres, Redis, object storage, and Elasticsearch. That changes the decision from “Can it run in our cloud?” to “Which capabilities, operational dependencies, encryption controls, upgrades, and support obligations do we accept?”

Nango 文档区分了面向 Auth 与 Proxy 的有限免费自托管路径，以及能力更完整的企业自托管平台。完整架构包含多个 Node 服务，以及 Postgres、Redis、对象存储和 Elasticsearch。因此问题不应只是“能否跑在我们的云里”，而应是“接受哪些能力、运维依赖、加密控制、升级和支持责任”。

Run one shared workload before choosing选型前跑一套共享工作负载

Marketing comparisons are not benchmarks. Create one test tenant and run the same sequence on every candidate. Capture raw responses, timestamps, log IDs, provider request IDs, retries, and final normalized output.

营销对比不是 Benchmark。建立一个测试租户，在所有候选方案上运行完全相同的序列，并保存原始响应、时间戳、日志 ID、供应商请求 ID、重试和最终标准化输出。

{
  "workload": "customer-crm-agent",
  "steps": [
    "authorize with minimum scopes",
    "read 100 records with pagination",
    "refresh an expired token",
    "create one idempotent record",
    "receive and replay one webhook",
    "resume an incremental sync",
    "revoke access and verify cleanup"
  ],
  "acceptance": {

Go-live validation checklist上线验收清单

A successful demo proves only the happy path. Approve production use only when the same tenant-aware workload passes identity, recovery, data, safety, observability, cost, and exit tests.

Demo 成功只证明理想路径。只有同一套租户感知工作负载通过身份、恢复、数据、安全、可观测性、成本和退出测试后，才应批准生产使用。

• Identity: every connection and tool call resolves to the expected internal tenant and external account.
• Recovery: expired tokens, 429 responses, provider 5xx errors, timeouts, and webhook replay recover without duplicate writes.
• Data contract: pagination, timestamps, deletes, optional fields, and provider-specific extensions remain explicit.
• Action safety: privileged tools require the intended confirmation, scope, policy, idempotency, and audit evidence.
• Observability: one trace links the agent request, selected tool, connection, provider request, retries, output, and answer.
• Cost: a representative month fits the budget under normal traffic and at least one realistic burst scenario.
• Exit: connections, code, records, cursors, logs, and deletion evidence can be exported or reconstructed.

• 身份：每个 Connection 与 Tool Call 都解析到预期的内部租户和外部账户。
• 恢复：Token 过期、429、供应商 5xx、超时和 Webhook 重放能够恢复且不产生重复写入。
• 数据契约：分页、时间戳、删除、可选字段与供应商扩展保持显式。
• 动作安全：特权工具具备预期的确认、Scope、策略、幂等和审计证据。
• 可观测性：一条 Trace 能关联 Agent 请求、所选工具、Connection、供应商请求、重试、输出与答案。
• 成本：代表性月份在正常流量和至少一个真实突发场景下都符合预算。
• 退出：Connection、代码、记录、Cursor、日志与删除证据可导出或重建。

Where QVeris fits—and where it does notQVeris 适合什么，以及不适合什么

• Use Nango or a similar control plane for customer-owned SaaS credentials and long-lived product integrations.
• Use an agent-first platform when tool execution, per-user permissions, and session orchestration dominate.
• Use QVeris when domain coverage, financial identity, freshness, provenance, and answer evidence dominate.

• 客户持有的 SaaS 凭证与长期产品集成，使用 Nango 或同类控制平面。
• 工具执行、按用户权限和 Session 编排占主导时，使用 Agent-first 平台。
• 领域覆盖、金融身份、新鲜度、来源和答案证据占主导时，使用 QVeris。
