ScreensConcept
Desktop and mobile: Developers write and configure scripts on desktop, while on-call approvals and re-runs happen from a phone console when needed. Sample screens on a computer and a phone, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Spoolwork takes a plain script and gives it three front doors: a webhook URL, a generated input form and a schedule. Chain scripts into flows with retries and approvals. Your team stops writing glue code and one-off job runners for internal automation.
It is built for developers and infrastructure teams who keep internal tools, data jobs and ops tasks running. Run it on your own servers or use the hosted version. A phone-ready console lets the on-call person see runs, read logs, approve a step or re-run a failure.
The material points to three gaps: proprietary low-code tools, heavy orchestrators, and hosted engines that need ongoing management. Spoolwork keeps scripts as ordinary code in your repository, so leaving costs you little.
- Tagline
- Scripts in, working automation out. Run it where you want.

- Why this name
- A spool holds thread that gets woven into cloth. Scripts are the thread, flows are the work. Two plain words joined, easy to say.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Script to webhook in one step
Save a script and get a callable URL with typed inputs, auth keys and a request log. No server to write.
No member yet
Auto-generated input forms
Function arguments become a form teammates can fill in, so non-developers can run a script safely.
No member yet
Flows with retries and approvals
Chain scripts, branch on results, retry on failure and pause for a human to approve before a risky step.
No member yet
Schedules and event triggers
Run on a cron schedule, on a webhook call or when another flow finishes. Missed runs are flagged.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Users invite others. A script's owner invites teammates to run forms, approve steps and watch runs. Each approver or requester who gets a run link meets the product inside real work.
- Do they become customers?
- Invited teammates can become paying seats, but many will only approve. Test whether approvers push their own teams to adopt it or stay viewers.
- First customers
- Platform and DevOps leads at companies of 20 to 200 staff who run internal scripts by cron or chat and want approvals and logs without a new heavy system.
- Where to reach them
- Developer communities: Post worked examples of turning a real ops script into a form with approval in Hacker News-style and DevOps forums.
- Open-source self-host guide: Publish a ten-minute install guide and templates; offer hosted upgrade inside the app.
- Direct outreach: Contact teams that complain about Airflow or hosted engine costs and offer a migration of one workflow.
- First milestone
- Ten teams run a production workflow for 30 days and three of them pay for Team or Business.
Why people already pay for this
- VerifiedRetool's pricing page lists 2 paid plans, from €9 to €46 a month, plus a free plan and prices on request for larger customers
- VerifiedTemporal's pricing page lists 2 paid plans, at $500 a month, plus a free plan and prices on request for larger customers
- VerifiedGitHub repository gained 18136 stars in 1618 days
- Public claimWindmill is positioned as an alternative to proprietary platforms (Retool) and existing workflow orchestration solutions (Airflow, Temporal), indicating market demand for workflow automation.

RisksAI inference
- CommercialThe material shows an open-source project with 18,136 GitHub stars already covering this ground. A new entrant must win on a narrow niche, not on features.
- TechnicalRunning untrusted scripts safely is hard. A sandbox escape or noisy neighbour would harm customers and trust.
- CommercialPerformance claims against Airflow are the competitor's own and unverified. We cannot promise speed without our own benchmarks.
- PlatformA PWA suits the monitoring and approval console, but not editing code. Editing stays on desktop.
- CommercialSelf-hosting is free, so conversion to paid hosting or support must be proven. Willingness to pay is not shown in the material.
