nox.markets vs Agent builders (Lindy, Relevance, and peers)

That's a workshop. We're a store — build the agent yourself, or buy the one already built and measured.

01 — Honest read / 4 of 10 rows they win

What they do well sits at the same rank as where you strand.

These three columns are the same size on purpose. A comparison that shrinks the competitor's strengths is marketing, and this page should not ship that way.

01 — they

What they do well

Lindy, Relevance AI, Gumloop, and the rest of the canvas tools are a better abstraction than “call the API” and a better prototype loop than a six-month consultancy. A technical operator can specify a job, attach tools, give the agent a mailbox or a knowledge base, and see behavior in days. That speed is real.

They are not the same product. Lindy is closer to an end-user agent for email, calendar, and phone work — a capable assistant you configure. Relevance is closer to an operations workbench: knowledge, tool use, teams of agents, a builder who thinks in workforces. Gumloop sits nearer Make: visual, operator-friendly, still a canvas. Collapsing them into one villain is how comparison pages get a reputation. What they share is the contract: you bring the expertise, they bring the runtime. For a unique process and a builder on staff, that contract is the correct one.

02 — choose them

When to choose them

Choose an agent builder when the job is not in anyone's catalog and a technical operator will own it — including evaluation, tool failures, and model changes. Choose Lindy-like tools when the work is “live in Gmail/Calendar and take actions as me.” Choose Relevance-like tools when you are standing up a research or ops workforce on a knowledge base you will maintain.

Choose them instead of us for the 20% that is actually custom. Choose them when you need to find out whether a job is automatable before it deserves a SKU; a two-week prototype on a canvas is cheaper than waiting for our roadmap. If the buyer is the builder, this page should often lose.

03 — strand

Where you strand

A canvas is a project. The ICP has the least of what the canvas demands: attention. First agent is not 45 minutes; it is specification, tool auth, sad-path design, and “looks good in the demo” that decays when the vendor PDF changes. There is rarely a published accuracy number that was produced by someone other than the builder.

When the model provider deprecates an endpoint, the project reopens — on their calendar, not ours. Three agents later, the operator is a part-time ML-lite maintainer. Marisol has abandoned two tools that needed a warehouse she does not have. A canvas that needs her to become the eval harness is the same movie.

03 — Hours and price

Hours are leftover tax, not a benchmark we timed on their product.

3 production agents × 3h/month of eval-by-eyeball and prompt/tool fixes when models move (~9h) + first-build time amortized (20h × 3 agents / 12 months ≈ 5h). One-agent shops should use 20h/12 + 3h ≈ 5h, not 14h.

04 — Migration / 5 steps

Complement first. Migration is surgical.

  1. If a canvas agent is in production, measured, and owned, do not migrate it for brand reasons. Complement: next commodity job is a SKU, next unique job stays on the canvas.
  2. If the canvas agent is a graveyard of half-prompts, freeze new agents. Pick one repeating job that matches a SKU (collections → duesday, unused SaaS seats → seatcheck). Ship that. Use the win to decide whether the graveyard gets rebuilt or deleted.
  3. Do not expect a clean export from Lindy/Relevance into our config. Plan a parallel run, not a file conversion.
  4. Tool connections: re-OAuth into the SKU. Revoke the canvas agent's scopes when the SKU has matched it for a week.
  5. Keep the builder tool for prototypes. The rule to write down: “If it is still on the canvas after 30 days in production, it needed a SKU or it needed a real owner.”

05 — FAQ / 3 questions

Three questions a skeptic actually asks.

  • 01Lindy already reads our Gmail. Why buy Duesday?open

    If Lindy (or anything else) already sends the right reminder, on the right day, from the AR mailbox, and logs the chase on the invoice in QuickBooks, you don't. Duesday is $99/mo to stop being the person who owns that prompt. “Reads Gmail” is not the job; the job is cadence + suppress-in-dispute + stop-on-paid + invoice note.

  • 02Isn't your 'agent' just a prebuilt Lindy template?open

    A template still leaves eval, integration, and model change on the buyer. A SKU is those three paid for. If we ever ship templates on someone else's canvas, they are not this catalog.

  • 03We'll outgrow your catalog. Then we need a builder anyway.open

    Then you buy a builder then, for the jobs we declined. That is the 20%. Paying workshop rent on the 80% that is invoice matching is how the ICP stays in pilot purgatory.

Three questions about Agent builders (Lindy, Relevance, and peers). Answers are in the page, not behind a scripted accordion.
