# What low-code tools connect with existing enterprise systems like Salesforce, SAP or legacy databases without requiring custom connectors?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Integration is the thing that looks easy on the product sheet and turns out to be the hardest part in practice. We're looking at <a class="a a--md" elv="true" href="https://www.g2.com/categories/low-code-development-platforms">low-code development platforms</a> specifically from the angle of how well they actually connect to enterprise systems like Salesforce, SAP, and legacy databases, without requiring a custom connector build for every touchpoint.</p><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">A few platforms that come up in this context:</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/agentforce-360-platform-formerly-salesforce-platform/reviews"><strong>Agentforce 360 Platform (formerly Salesforce Platform)</strong></a><strong>:</strong> The native Salesforce connectivity is obviously the headline here. For organizations building inside the Salesforce ecosystem, it removes most integration friction entirely. The question is how it handles anything outside that ecosystem, where external integrations can require additional configuration.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/microsoft-power-apps/reviews"><strong>Microsoft Power Apps</strong></a><strong>:</strong> Mid-market reviewers highlight the breadth of the connector library (1,400+ pre-built connectors) as a real differentiator. The Microsoft 365 and SharePoint integration is frictionless. The common criticism is that non-Microsoft systems effectively feel like second-class options, often requiring premium licensing or custom connectors for anything outside the ecosystem.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/outsystems/reviews"><strong>OutSystems</strong></a><strong>:</strong> Enterprise reviewers describe using its integration layer to connect modern interfaces to legacy systems, specifically mentioning it as a reason they could modernize incrementally rather than ripping and replacing. Custom connectors exist as an extensibility point, but the platform's integration architecture is treated as a core capability rather than an afterthought.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/servicenow-app-engine/reviews"><strong>ServiceNow App Engine</strong></a><strong>:</strong> Strong native connectivity to enterprise IT systems and ITSM data. Integration outside the ServiceNow ecosystem typically requires more effort. Appian reviewers in financial services mention HTTP and OpenAPI integration as especially practical for connecting to loan systems and third-party APIs without bespoke development work.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/appian/reviews"><strong>Appian</strong></a><strong>:</strong> Financial services reviewers specifically call out the HTTP and OpenAPI integration layer as practical for connecting applications to external systems quickly. Some enterprise reviewers note that on-prem system connectivity remains an area to watch.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Which of these have you tested against legacy infrastructure specifically? And has anyone tried building integrations to SAP or older database systems without a full custom connector build?</p>

&lt;p&gt;&lt;span style=&quot;background-color: transparent; color: rgb(0, 0, 0);&quot;&gt;The connector count on a spec sheet and the connector you actually need rarely line up. A few things worth separating when you evaluate:&lt;/span&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;span style=&quot;background-color: transparent;&quot;&gt;Common SaaS systems are usually well covered by pre-built libraries, so those are rarely the problem.&lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span style=&quot;background-color: transparent;&quot;&gt;The moment SAP or an older on-prem database enters the picture, &quot;no custom work&quot; tends to become &quot;some custom work.&quot;&lt;/span&gt;&lt;/li&gt;&lt;li&gt;The useful question is less about how many connectors exist and more about how the platform handles the one legacy system nobody has a clean connector for.&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;
