Development subscription vs agency: which should you choose?
An agency sells a project: a defined scope, a price and an end date, with changes quoted as they come. A development subscription sells continuing work for a flat monthly fee, with changes absorbed within the plan. Choose an agency for a well-defined build with a clear finish. Choose a subscription for a live product that changes every week and needs someone responsible for running it.

How is a development subscription different from an agency?
The difference is what the price buys. An agency prices a project, fixed or by the hour, and the engagement usually ends at launch. A development subscription prices continuing work on a live product for a flat monthly fee, so changes, releases and running the product sit inside one plan rather than being quoted one by one.
| Software agency | Plutonapps subscription | |
|---|---|---|
| What you buy | A project with a scope and an end date | Continuing engineering of a live product |
| Price | Quoted per project; Clutch reports most listed firms charge $24–$49/hour and projects typically cost $10,000–$49,000 | Starter $2,999/mo billed yearly or $3,999/mo month to month; Growth priced per product |
| Changing your mind | A change request, re-quoted | No per-change fee, within fair use and plan capacity |
| Releases | As the contract sets out; often at milestones | Two production deployments a week on Starter; continuous on Growth |
| Quality checks | As the contract specifies | Regression and visual regression tests, code review and security checks on every change |
| After launch | Handover, or a separate retainer | Monitoring and emergency support included |
| Ownership | Usually yours on final payment; check the contract | Yours throughout: code, data and infrastructure |
Is a development subscription cheaper than an agency?
Not always. For a one-off build with a clear end, an agency project can cost less than a year of a subscription. Clutch, which publishes pricing from verified client reviews, reports an average project cost of about $132,000 over roughly 13 months, but a typical range of $10,000 to $49,000. A year of our Starter plan billed yearly is $35,988.
The comparison changes once the product is live. An agency project usually ends at launch, and the work that follows (bug fixes, security updates, new features, incidents) is bought again as change requests or a retainer. A subscription prices that continuing work in from the start. So compare the cost of the first twelve months including what happens after launch, not the cost of the build alone.
How do agencies and subscriptions handle changes and risk?
A fixed-scope agency quote carries the agency's estimate of risk: unclear requirements and likely changes are priced in, and anything outside the scope is a change request. That protects both sides when the scope really is fixed. It works against you when you are still learning what the product should be, which is common for early products.
A subscription moves that risk into capacity instead of price. You change priorities whenever you like, and the team works through your queue at the capacity your plan reserves. The limit is capacity, not a quote: on Starter, an engineer starts on a change within up to two business days, which is when work begins, not a promise of when the whole change is finished.
What is included in a product engineering subscription?
- Building: from small UI adjustments to large features and major product changes such as new data models, migrations and integrations.
- Quality and security: regression and visual regression testing, code review by an engineer other than the author, and security checks on every change.
- Releases: changes reach production through CI/CD, twice a week on Starter and continuously on Growth.
- Running it: monitoring, and emergency production support (five events a month on Starter, unlimited on Growth).
- Advice: consulting sessions and architecture reviews with the engineers on your product.
The full list, and what Growth adds, is on our pricing page. Third-party infrastructure you own, such as hosting and databases, is billed to you directly at cost.
How is this different from an unlimited design or development subscription?
The word subscription covers very different services, so check what the queue actually holds. Designjoy, for example, lists a monthly membership at $4,995 (shown as a discount from $5,995) for design work and Webflow development, one request at a time, which suits brand, marketing and interface design. Awesomic's All-in-One plan, at $2,995 a month, offers part-time specialists across design, no-code, marketing and development. Ours is narrower: engineering a live application's data, security, tests, releases and operations, with the team that ships the change also responsible for running it.
When is an agency the better choice?
- The scope is genuinely fixed, such as a campaign site or a one-off internal tool.
- You need a large team for a short burst, then little change afterwards.
- You already have engineers who will own the product after handover.
- Your procurement requires a fixed-price contract with deliverables.
If none of those describes you, and the product will keep changing after launch, compare a subscription on your own numbers. Our full comparison also covers freelancers and in-house hires.
Frequently asked questions
What does a year on a development subscription cost?
A year of the Plutonapps Starter plan billed yearly is $35,988, or $3,999 a month month to month, with infrastructure you own billed at cost. For a live product that keeps changing, that can cost less than an agency over a year, because fixes and new features are included rather than quoted separately.
What does unlimited changes mean on a Plutonapps plan?
There is no per-change fee and no ticket quota. We work through your queue continuously at the capacity your plan reserves, within fair use, prioritising with you rather than counting requests.
Can I cancel a development subscription?
Yes, at any time. A month-to-month Starter plan stops at the end of the current billing month. A yearly plan can be refunded in full within 7 days of purchase; after that it runs to the end of the paid year. Our refund policy has the details. If you stop, you keep everything: we hand over the repositories, infrastructure and documentation.
Who owns the code on a subscription?
With Plutonapps, you do, from the start: the code, the data and the infrastructure belong to you, and we build and operate them on your behalf.
Do agencies offer support after launch?
Many do, often as a separate maintenance retainer or support contract. Ask what it covers, such as security updates, monitoring and response times, and price it into your comparison.
