5 alternatives to Merge in 2026

Why teams look for a Merge alternative

Merge is a capable unified API, and for HR data it's one of the strongest on the market. The friction starts when your product runs on financial data and your customers are in Europe.

Merge spans eight categories, and its accounting catalogue lists roughly a dozen platforms, all cloud-based. No POS, no invoicing, no payments, no PMS.

Here are five Merge alternatives worth evaluating in 2026, and what each one is genuinely good at.

1. Chift: best for real-time financial connectivity in Europe and AI agents

Chift is the integration platform that brings business software together. One integration gives you 150+ connectors across accounting, invoicing, POS, e-commerce, payments and PMS. Every call goes live to the source by default, so you read the current state, not a snapshot from the last sync. Chift handles authentication, data mapping, rate limits and maintenance, so your engineers integrate once and move on.

Chift goes deep in the financial and operational categories a SaaS or fintech actually ships on.

Pros

• Real-time by default, synced when you need it. The unified API does a live round-trip to the source on every call. Any connection can switch to an opt-in datalayer, a synced copy built for heavy analytical and paginated queries, with your integration code unchanged. Most platforms pick one model for you and you live with it.
• On-premise software, connected like cloud software. Our local agents make real-time calls into software running on a client's own server, including Sage 100 FR, Sage 200 ES and a3ERP. For the end user it's a one-time install. For you it's just another connector.
• AI agents that stay inside the lines. Chift's MCP server exposes a governed semantic layer, so a model picks from curated measures instead of writing raw SQL. It cannot invent fields, cross tenant boundaries, or add two currencies into one total.
• Largest European accounting coverage built market by market. Pennylane in France, DATEV in Germany, Exact Online in the Netherlands, WinBooks in Belgium, a3ERP in Spain, and the long tail behind each. Servers hosted in Europe, ISO 27001 certified, GDPR built in.
• Expertise on European market and connectors. The large range of connectors allowed for deep technical knowledge and expertise in European markets.
• Integration variety and knowledge. 6 different APIs supported, allowing various vertical SaaS to develop their integration in different sectors.
• Support that speaks both languages. Engineering questions and commercial ones, answered by people who've shipped these connectors themselves.

Cons

• No HR, ATS, CRM or ticketing categories. If people data is core to your product, you'll need a second platform alongside us.
• Our centre of gravity is Europe. If your roadmap is US-first, other platforms have more coverage there.

Best for: Fintechs, accounting tech, vertical SaaS, banks and finance AI agents with customers in Europe  and AI features that need reliable context.

2. Apideck: best for broad category coverage

Apideck is a unified API covering accounting, CRM, HRIS, e-commerce, file storage, ATS and ERP, with around 190 connectors.

Pros

• No cache: every call fetches live from the source, so there's no sync lag and no copy of your customers' data sitting on an intermediary.
• Transparent per-consumer pricing and an embeddable integrations marketplace.
• An MCP server with scoped access, read/write controls and field-level redaction.

Cons

• Real-time only. There's no synced store for heavy analytical or paginated workloads, so you inherit the source system's speed and availability on every read.
• The category set stops short of POS, PMS, invoicing and payments.
• No real on-premise solutions.
• Primarily self-serve, without no-code sync product for non-technical teams.
• Lack of expertise due to their horizontal coverage.

Best for: developer-first SaaS teams that want live data and a polished developer experience across accounting, CRM and HRIS, mainly in US and Benelux markets.

3. Codat: best for lenders and banks underwriting SMBs

Codat connects banks, lenders and fintechs to their small-business customers' financial systems, integrating with around 30 accounting, ERP, banking and commerce platforms and packaging them into lending, bank feeds and spend-analytics products.

Pros

• Purpose-built products for lending, bank feeds and spend analytics, not just raw connectivity.
• Real on-premise support through white-labelled Windows connectors for QuickBooks Desktop and Sage 50 UK and Ireland.
• UK data residency, with mature enterprise-grade logging and monitoring.

Cons

• The product surface maps to underwriting, not to a SaaS vendor shipping integrations to its own customers.
• Sync-and-cache only, so a copy of your customers' financial data sits in Codat's infrastructure.
• No first-party MCP server as of mid-2026.
• On-premise coverage targets UK and US desktop software rather than continental European systems.
• Fully custom pricing, which slows down early evaluation.
• No coverage outside of UK and US.

Best for: banks & lenders in the UK and US extracting structured financial data from SMBs for credit decisions, card programmes or analytics.

4. Kombo: best for European HR and payroll data

Kombo is a European unified API founded in 2022, focused on HRIS, ATS and payroll, running on a sync-and-store architecture.

Pros

• 100+ integrations across HRIS, ATS and payroll.
• Strong coverage of European HR tools that US-first platforms often miss, including Personio, Factorial, HiBob and Teamtailor.

Cons

• HR only, and cloud HR at that.
• Any product that also needs accounting, POS, payments or invoicing will need a second platform alongside it.
• No first-party MCP server as of mid-2026, so agents connect through standard REST APIs.
• Observability and error detection are lighter than on more mature platforms.

Best for: HR tech companies that need deep, reliable coverage of European HRIS, ATS and payroll.

5. Nango: best for teams that want to own the infrastructure

Nango is the open-source, code-first option. Rather than handing you fixed schemas, it gives you auth across 1,000+ APIs and lets you write the integration logic as TypeScript functions you version and deploy yourself.

Pros

• Open source and self-hostable, with no vendor lock-in on your data models.
• Full control over field mappings and sync logic, which matters when integrations are core to your product rather than a checkbox.
• A native MCP server, so the same platform powers agent tool calls and product integrations.

Cons

• You build the unified layer. Pre-built vendors hide the source APIs' quirks, Nango doesn't, and that work is smaller with AI coding agents but never zero.
• The free self-hosted edition covers auth and the proxy only. Functions, syncs and the MCP server need a paid plan, and full self-hosting is an Enterprise arrangement.
• Self-hosting moves uptime, security and compliance onto your team.
• No pre-built depth in European accounting software, and no on-premise agent for desktop ERPs.

Best for: engineering teams with DevOps capacity, strict data residency requirements, or integrations so central to the product that owning the logic beats renting a schema.

How to choose the right Merge alternative

For fintechs and financial software: Chift goes deep on financial data, but for different buyers. Chift is built for software vendors shipping integrations to their own customers, covering accounting, invoicing, payments, POS, e-commerce and PMS through one contract. For the US market, Codat is built for institutions consuming SMB financial data, with lending, bank feeds and spend analytics packaged as products. If you're the one embedding connectivity in a product, Chift is the closer fit.

For banks and neobanks: Codat and Chift both offer solutions for banks and neobanks. Codat has the longer track record in UK and US underwriting. Chift covers continental Europe market by market, including the on-premise software a large share of European SMBs still run their books on, which matters if your lending or cash-management product needs to reach customers beyond the UK. More on that on our banks and neobanks page.

For vertical SaaS with European customers: this is where Merge's category coverage falls short fastest. Hospitality needs PMS, retail needs POS, field services need invoicing, and none of the three are in Merge's catalogue. Chift covers all of them alongside accounting. Apideck reaches ERP and e-commerce but stops before POS, PMS and payments.

For developer-first teams that want full control over every connector: Nango. It’s open-source, so your engineers can read, fork and change the code, and customise each integration down to the field level. Auth is handled for you, and the integration logic lives in your codebase, versioned like the rest of your product. The trade-off is that flexibility comes with ownership: your team writes the sync logic and data mapping, and keeps maintaining it every time a provider changes its API.

For HR and people data: Kombo and APIdeck if your customers are European. Merge itself if your customers are mostly US and you need Workday, ADP and BambooHR depth. Neither will carry a product that also needs financial data, so plan for two platforms.

For maximum control: Nango, if you have DevOps capacity and integrations are central enough to your product that owning the logic beats renting a schema. Expect to build the unified layer yourself, and to take on uptime, security and compliance with it.

For products with AI features: For products with AI features: Chift, Merge, Apideck and Nango all expose connectors over MCP. The differentiator is what happens when an agent touches financial data. Chift’s MCP server sits on top of its data layer, a synced and normalised copy of your customers’ accounting data, so agents can answer analytical questions like revenue per month or receivables by client in seconds, without hammering the source ERP. On top of that data sits a governed semantic layer: the model picks from curated measures rather than writing queries, and structurally cannot invent a field, cross a tenant boundary, or add two currencies into one total.

The pattern underneath all of them is the same. Horizontal platforms give you breadth with shallow depth in any single category. Focused platforms give you depth in a category that may or may not be yours. The question isn't which platform is best, it's which one was built for the data your product actually runs on.

Frequently asked questions

Is there a Merge alternative that covers POS and payments?

Yes. Merge doesn't cover POS, payments, invoicing or PMS at all. Chift covers all four alongside accounting and e-commerce, so a product that needs financial and operational data from one vendor doesn't have to split across two platforms.

Which Merge alternative supports on-premise accounting software?

Chift and Codat are the two with a real on-premise story. Codat ships white-labelled Windows connectors for QuickBooks Desktop and Sage 50 UK and Ireland. Chift's local agents cover continental European desktop software including Sage 100 FR, Sage 200 ES and a3ERP.

Which Merge alternatives give you real-time data?

Chift, Apideck and Nango all read live from the source rather than serving a cached copy. The difference is what happens when you need the other model: Chift lets any connection switch to a synced datalayer for analytical and paginated workloads without changing your integration code, while Apideck is real-time only.

How hard is it to migrate away from Merge?

Most unified APIs follow similar REST patterns, so the work is mainly remapping your API calls to the new schema, usually measured in days rather than weeks. The bigger question is whether your end users need to re-authenticate. Ask any platform you evaluate about token migration before you plan the switch.

Do I need a separate platform for AI agents?

Not necessarily. Several platforms now expose their connectors through MCP, including Chift, Apideck and Nango. What differs is the governance behind it. Chift's MCP server runs on a semantic layer, so an agent picks from curated measures rather than writing queries, which keeps it from inventing fields or mixing currencies in a total.
