Zapier, n8n, or ParkWalk?
Teams that already automate work ask us this one early, usually phrased as "we have two hundred zaps, why do we need agents?" Often you don't. All three products run work without a person at the keyboard; they part ways on what happens when a run needs someone to read, weigh, and decide.
What each one is for
The biggest catalog of triggers and actions
A form entry becomes a CRM row becomes a Slack ping, wired together in an afternoon by whoever owns the process, no engineers involved. Zapier's catalog covers thousands of apps, and for event-shaped work it is the path of least resistance.
The node graph you can run under your own roof
The same trigger-and-steps model, drawn as a node graph, with real code steps where the built-in nodes run out. You can self-host it, which is why it wins wherever data residency or an infrastructure team gets a vote.
Workflows you design, agents run without you
ParkWalk is for the runs that aren't identical: an agent reads what it finds, plans the pass, asks you at the judgment calls, and puts the result in front of a person before it counts. Write the work down once; run it once, on a schedule, or continuously through a loop that owns a goal.
You wire Zapier. You program n8n. You delegate to ParkWalk.
Zapier and n8n are automation: the path through the work is decided before the work arrives. A trigger fires and the steps you drew in advance run, identically, ten thousand times, for pennies. That determinism is the product, and when the path really is fixed, nothing beats it.
ParkWalk is delegation: the goal is decided in advance, and the path is not. Each run, the agent reads what's actually there, plans the pass, and works inside the lines you set. When it hits something the workflow says a person should decide, your phone gets a question with options, and the run keeps moving around it. Nothing counts until someone gives a verdict.
The failure modes tell the same story. Automation fails at the edges: the weird invoice takes whichever branch you happened to draw, and edge cases accumulate as ever-deeper branching until the flow is software someone maintains. Delegation fails without structure, which is why ParkWalk makes you write the structure down before anything runs.
Who should buy what
Zapier
Every demo request should create a CRM contact, post to #sales, and start the drip sequence. It happens four hundred times a month and it should happen the same way all four hundred times. Whoever owns marketing ops wires it in an hour and never thinks about it again.
- Notifications, syncs, and lead routing
- Glue between SaaS apps, built by non-engineers
- High volume where per-run cost matters
- Event-shaped work: when X happens, do Y
n8n
The customer-data sync has to run inside your VPC, hit an internal API, and reshape the payload with twenty lines of code in the middle. An ops engineer draws the graph, writes the code node, and owns it from then on. It's automation, held to infrastructure standards.
- Flows that need real code in the middle
- Internal and custom APIs beyond any catalog
- Self-hosting for residency and control
- Teams with someone to own the graphs
ParkWalk
Weekly CRM hygiene: merge the duplicates, chase the stale deals, draft follow-ups for anything quiet past twenty days. No two weeks look alike, which is exactly why it never got automated. An ops lead writes it down once, with one rule: the agent updates records alone, but anything customer-facing waits for a yes. The Monday sweep now ends as three check-ins on a phone and a verdict.
- Runs that need reading and judgment in the middle
- Output someone signs: drafts, reports, decisions
- Work that touches money, customers, or production data
- Standing goals a loop can own, like pipeline hygiene
Recurrence isn't what makes work delegable. Structure is.
Automation platforms only pay off on work that repeats, because the flow costs more to build than any single run is worth. That habit runs deep enough that "does it recur?" has become the test for whether software can take work off your plate.
ParkWalk uses a different test: can you write it down? A migration that will run exactly once still deserves steps, checks, and a review, and an agent can run it inside them tonight. A goal with no fixed cadence at all, like keeping receivables clean, can't be scheduled, but a loop can own it: plan the next task, run it, report back, stay inside a budget. The goal stays. The tasks change.
Don't migrate your zaps
Working automation is a solved problem, and re-solving it with agents buys you nothing but a model bill. Port only the work your flows never managed to hold: the reviews, the triage, the drafting, the runs that kept needing a person in the middle. If a zap has run clean for a year, the kindest thing you can do is leave it alone.

| ZapierYou wire | n8nYou program | ParkWalkYou delegate | |
|---|---|---|---|
| Built around | A catalog of triggers and actions | A node graph, with code steps, self-hostable | A workflow your team designs, versions, and owns |
| You provide | The exact steps, in advance | The graph, plus code where nodes run out | The goal, the guardrails, and the tools it may touch |
| Each run | Identical by design | Identical by design | Planned fresh against what the agent finds |
| When a run is ambiguous | Takes whichever branch you drew | Same, unless someone coded for that case | The agent reads, decides, or asks you |
| When it needs a person | Failures land in the run history | Failures land in logs and alerts you set up | A decision on your phone, mid-run, with options |
| What comes back | Data moved between apps | Data moved, plus whatever your code steps did | A reviewable result with a trace of every action taken |
| Quality control | Spot checks and the run history | The monitoring you build around it | Check-ins you defined, then a required verdict: approve, send back, or dismiss |
| Ongoing goals | Schedules re-run the same flow | Schedules and queues re-run the graph | Loops hold a goal, choose the tasks, and report back, inside a budget |
| Permissions | Per-app connections you authorize once | Credentials you host and manage yourself | Per-role scope ceilings, approval gates on risky actions, and budgets, enforced at execution |
| Buying motion | Self-serve, priced by tasks per month | Open to self-host; paid cloud and enterprise tiers | Free to start, per-seat, cheaper when you bring your own model keys |
| Best first win | "The busywork between apps disappeared" | "Automation our infra team signed off on" | "A process moves to the background" |
How they fit together
The realistic end state isn't one winner. It's plumbing that stays plumbing, and judgment that finally gets delegated.
ParkWalk ships an n8n connector
An agent can start the flows you already trust as one step of a bigger task: judgment in ParkWalk, plumbing in n8n, each doing the part it's built for.
Automation can start a walk
ParkWalk's public API starts tasks and walks, so a zap or an n8n flow can escalate: when a case needs judgment, the automation hands it up instead of guessing.
The split most teams land on
Events with fixed responses stay in Zapier or n8n. Work with a person in the middle moves to ParkWalk, and the person moves to a phone.
Three questions to ask about any piece of work
If every run should be identical, that's automation, and it should cost pennies. Wire it and move on.
A branch can't weigh evidence. If a person sits in the middle of the flow today, that's the part to delegate, not to wire.
Data moved silently is fine for syncs. Money, customers, and records need a verdict someone can stand behind later.
No on all three: Zapier, or n8n if it has to live on your infrastructure. Yes to the second or third: write it down in ParkWalk. And if the yeses describe a standing goal rather than a single piece of work, that's a loop.
Start where your flows kept needing you
Somewhere in your automation there's a step that says "notify a human." That step is a process waiting to be written down. Scope it tight, run it in a walk, and see whether you trust what comes back.
