AI Agent Workflow Platform

Durable agent runtime with error recovery for ops teams — an execution OS, not a template marketplace or Zapier clone.

An ops lead at a 40-person SaaS company maps the same broken loop every Monday: a Salesforce opportunity moves to "Closed Won," someone is supposed to provision the workspace, send the welcome sequence, open a Slack channel, and file a kickoff task in Linear. Step two fails because HubSpot rate-limited. The zap retries once, posts a cryptic error into a channel nobody watches, and the customer sits in onboarding hell until a human notices on Thursday. The company already pays for Zapier, a bit of Make, and a graveyard of n8n JSON. What they do not have is a runtime that can recover — diagnose the failure, try a fallback, escalate with context, and resume without a human re-running the whole graph.

Built for Developers, Solo Founders.

Suggested stack: Next.js + Vercel, Temporal, LangGraph or a custom agent loop, Postgres, Salesforce and HubSpot connectors, Stripe. Weekend scope: about 8 hours.

The Solution

RelayOS (working name) is a runtime for autonomous agent workflows with error recovery, positioned as the ops OS for teams — not a template marketplace, not a solopreneur zap…

Market Research

Precedence Research puts the AI agents market at $7.92 billion in 2025, reaching $236.03 billion by 2034, about 45.8% CAGR. That is the primary cite: large, compounding, still…

Competitive Landscape

Zapier — Default glue for SMBs. Enormous connector catalog, weak agent reasoning, retries that feel like "run it again." Free / Pro about $19.99–$28.75 / Team $69 / Company…

Business Model

Starter kit ($249 one-time) — One production workflow (onboarding or lead routing), two connectors, recovery defaults, a week of email support. Converts to Pro.

Recommended Tech Stack

Next.js + Vercel — App, graph editor, run inspector, billing. Workers do not live on Vercel serverless; they live on a long-running fleet.

  1. 1. Project Setup

    Build the weekend MVP of "RelayOS": a runtime where a plain-English job becomes an agent graph that retries, recovers and escalates instead of dying.
    
    Stack: Next.js (App Router), TypeScript, Tailwind, Supabase (Postgres, Row Level Security, Auth with email magic link), Temporal for durable runs, Claude for the compiler. Workers run in a separate Node process that hosts the Temporal activities. Deploy the app on Vercel.
    Tools: two mock tools only, a fake CRM write and a fake chat message. Real Salesforce and HubSpot come later.
    
    Tables (Row Level Security on, each user reads only their own rows):
    - graphs(id, user_id, name, dsl_json, version)
    - runs(id, graph_id, temporal_workflow_id, status, started_at, cost_cents)
    - run_events(id, run_id, seq, type, payload_json)
    - tool_contracts(id, provider, name, json_schema)
    
    Screens: /login, /graphs, /runs/[id] (the run inspector).
    Env vars (names only): NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY (server only), TEMPORAL_ADDRESS, ANTHROPIC_API_KEY.
    
    Do not build: billing or plans, Salesforce or HubSpot connectors, orgs or SSO, a template gallery, a graph editor.
    Done when: npm run dev starts, the worker connects to Temporal, you can sign in, and the four tables exist with Row Level Security on.
  2. 2. Core Feature

    Build the one feature that proves RelayOS: compile a job, run it, and recover when a tool fails.
    1. POST /api/graphs/compile takes a plain-English job and returns a typed graph: trigger, steps, retry policy, compensation and escalate_to. Validate every tool against tool_contracts.
    2. POST /api/runs starts a Temporal workflow for a graph. Each activity calls a mock tool with an idempotency key.
    3. On a 429 or 5xx from a tool, retry with exponential backoff, then use the fallback tool if one is set, then escalate with the run transcript.
    4. /runs/[id] shows every event in order, a Replay from step N button, and a Kill switch.
    Rules: never drop a failed step without writing a run_events row. Do not build a template gallery.
    Empty state: with no graphs, show a text box that takes the first job.
    Done when: a compiled job runs end to end, a mock tool that returns 429 twice still completes, and killing the worker mid-run resumes it when the worker restarts.
  3. 3. Landing Page

    Build a one-page landing site for RelayOS, a runtime for agent workflows with error recovery.
    Hero: "The ops OS that recovers." Sub: "Agents that retry, compensate and escalate, not zaps that die in a Slack channel." One button: Join the waitlist.
    Sections: the contrast (template libraries sell recipes, this runs production graphs), how it works in four steps (describe the job, connect systems, run with recovery, operate), a mock run inspector with a Replay button, and a short FAQ (it is not n8n with a skin, Temporal is the spine).
    Waitlist: store the email in a waitlist table in Supabase. No other service.
    Voice: precise and calm, written for an operations lead.
    Done when: the page renders on a phone and a submitted email appears in the waitlist table.
  4. 4. Branding Package

    Use a design or image tool for this one. A coding agent cannot draw a logo.
    Brand for RelayOS: a wordmark and an icon that suggest a relay baton passed between steps.
    Colors: a near-black, off-white and one signal color for a recovered run. Type: one sharp sans for the interface and a mono for run events.
    Deliverables: wordmark, icon, three run-state icons (running, retrying, recovered), and one launch graphic.
    Done when: each deliverable is saved in one folder and the wordmark reads at 18px.
