Best Workflow Automation Platforms for Agencies

No-code workflow automation built into Box's secure content layer for document approvals.

Editor's takeBox Relay ranks second among workflow automation platforms for agencies with a 9.4 score. Its 9.8 integrations mark reflects over 1,500 native connections, including Salesforce and Microsoft 365. The catch is access, Relay ships only with higher-tier Box plans, not as a standalone product.

24/7 cloud AI agent platform with a 180+ agent marketplace, running tasks even after you close the browser.

Editor's takeMuleRun gives each user a dedicated cloud virtual machine that keeps working after the browser closes, unlike chat tools that stop when you log off. Its marketplace already lists more than 180 specialized agents and has logged over 1.2 million interactions since its 2026 launch. Its terms of use place the burden of data exposure from third-party Creator Agents entirely on the user.

Enterprise automation platform combining RPA, AI and API integration for complex business processes.

Editor's takeUiPath combines traditional RPA with process mining, document understanding and new agentic AI orchestration, and seven straight years as a Gartner RPA Leader back its market position. ISO 27001, SOC 2 Type 2 and HIPAA Type 2 attestations make it a fit for regulated enterprises. The tradeoff is cost, since unattended robot licenses run roughly $1,300 to $1,400 per bot per month.

A no-code automation platform connecting 8,000-plus apps, now with AI tools for building and running workflows.

Editor's takeZapier's integration library remains the largest in the category, which is why most SaaS tools build a Zapier connection first. Its 2024 revenue reached $310 million with over 3 million users, evidence of durable market position. Costs rise quickly at scale, and reviewers point to competitors like Make as cheaper for high-volume automation.

No-code CRM combining sales, marketing, and service automation with autonomous AI agents built in.

Editor's takeCreatio pairs a full CRM with a no-code workflow engine strong enough to earn Forrester's top ranking for citizen developers. The Twin AI agents go past text generation into actual task execution. That depth comes with a real cost floor that rules out smaller teams.

Open-source automation engine unifying BPMN, CMMN, and DMN standards with AI agent orchestration.

Editor's takeFlowable stands apart by running BPMN, CMMN, and DMN process standards on a single open-source engine, then layering in AI agent orchestration as a first-class part of workflows. It carries ISO 27001 and SOC 2 Type 2 certification, and is named in Gartner's Market Guide for Business Process Automation Tools. The tradeoff is complexity: reviewers on TrustRadius and G2 describe a steep learning curve and an interface that can overwhelm non-technical users.

Developer-friendly workflow automation platform with a free self-hosted edition and native AI, LangChain agent support.

Editor's taken8n lets developers write JavaScript or Python inside workflow nodes and build LangChain-based AI agents, backed by a $180 million Series C that values the company at $2.5 billion, with Nvidia's venture arm among the investors. It counts an entire workflow run as one execution regardless of step count, unlike per-step competitors. Non-technical users face a real learning curve, and the Sustainable Use License limits commercial redistribution without a paid plan.

No-code automation built into Slack, connecting over 2,600 apps with conditional branching for routine tasks.

Editor's takeSlack Workflow Builder puts no-code automation directly where teams already talk, connecting to over 2,600 apps including Salesforce and Jira without leaving the chat window. It supports conditional branching up to 15 conditions per branch, letting non-technical staff build real logic. The limits show up at scale: workflows using connectors cap out at 1,000-2,000 runs per plan tier, billing $0.05 for every run beyond that, and HIPAA compliance requires the priciest Enterprise Grid tier.

No-code platform turning spreadsheets into apps, now with server-side workflow automation.

Editor's takeGlide's Workflows feature moves it past simple data display into server-side automation with loops and conditional logic, the kind of thing that used to require Zapier. SOC 2 Type 2 certification backs enterprise use. Pricing punishes growth, though. The Maker plan starts at $60 a month, but Business jumps to $249 with a hard cap of 100,000 accessible rows, and apps built this way cannot publish natively to app stores without a third-party wrapper.

Visual automation platform with routers, iterators, and an HTTP module for any API.

Editor's takeMake handles branching logic and data transformation visually, territory usually reserved for actual code. Pricing starts cheap at $9 for 10,000 operations, but polling triggers count against that quota even when they find nothing new, a detail worth checking before scaling a workflow.

AI workflow automation with built-in human-in-the-loop approval steps and GPT-4o included free.

Editor's takeRelay.app builds approval and data-input steps directly into automated workflows, letting a run pause for a human decision instead of failing silently. GPT-4o and Claude come included even on the free plan, which covers 200 steps a month. It scored 9.9 for support quality on G2, versus 8.3 for Zapier. The integration library stays thin at about 150 apps next to Zapier's 8,000-plus, and approval steps currently reach only internal Relay users, not external clients.
