Build a Lean Software Stack
Tell us what you're building and what you need. We'll create a simple starting stack without loading you up with unnecessary subscriptions.
What tools do you currently use?
Select the tools you currently use or pay for.
Your Software Stack
Pricing & calculation
Your current cost uses the reference price shown for each selected paid plan. Billing basis is shown below where applicable.
Prices are shown in USD and can vary by country, taxes, promotions, plan changes, and billing terms. Savings are conservative estimates based on detected overlap. The tool does not assume that you should cancel any subscription.
What the potential saving means: This is the largest overlapping subscription cost detected in your selected stack. It is not a guaranteed saving. Review whether one of the overlapping tools can be removed, downgraded, or replaced based on your actual workflow.
Possible overlap
Recommendations
Cost figures are reference paid-plan prices in USD. Actual prices can vary by plan, billing cycle, region, taxes and promotions.
How Lean Stack Builder Works
Select the software you currently use and Lean Stack Builder calculates the reference monthly and yearly cost of those paid plans. It then checks the selected tools for common areas of overlap, such as multiple project-management, design, AI, notes, or office tools.
When an overlap is detected, the tool shows it as an opportunity to review rather than telling you to cancel a subscription. You can compare your actual workflow, feature requirements, and plan limits before deciding whether a change makes sense.
How Potential Savings Are Estimated
Potential savings are deliberately conservative. The calculator uses the reference prices shown for the selected plans and avoids adding multiple overlapping opportunities together when the same subscription could be involved in more than one overlap. The result is a potential amount to review, not a guaranteed saving.
Who Is Lean Stack Builder For?
Lean Stack Builder is designed for freelancers, creators, side hustlers, designers, video creators, ecommerce businesses, agencies, and other small online businesses that want to keep their software stack focused and easier to manage.
What Is a Software Stack Audit?
A software stack audit is a structured review of the apps and subscriptions you use to run your work. Instead of looking at each subscription separately, you look at the whole stack together: what each tool does, what it costs, where two tools may cover similar jobs, and which services you actually need for your current workflow.
This matters because software costs rarely grow through one dramatic purchase. They usually grow a little at a time. A freelancer might add an AI assistant, a writing tool, a project manager, a design subscription, a scheduling app, cloud storage, and an automation service. Each purchase can make sense on its own while the combined stack becomes more expensive and complicated than the business needs.
Lean Stack Builder turns that review into a simple starting point. Select the tools you use, see the reference monthly and yearly cost, review potential overlap, and examine lower-cost options before changing anything.
Free Software Stack Cost Calculator
Use the calculator above to estimate the recurring cost of your selected software stack. The tool converts the reference plan prices in its database into a monthly and yearly view so you can see the combined cost in one place.
A software stack cost calculator is useful when individual subscriptions feel inexpensive but the total is difficult to see. For example, four or five subscriptions can look reasonable when viewed separately. The combined number can be much more useful when deciding which tools are essential, optional, or worth reviewing.
What the calculator shows
- Estimated monthly software cost for selected paid plans
- Estimated yearly software cost
- Potential overlap between selected tools
- Potential savings to review when overlap is detected
- Lower-cost or free options where the tool has a known alternative
- Reference pricing and billing basis for supported tools
How to Audit Your Software Subscriptions
A useful software subscription audit starts with the tools you already have, not a list of products you might buy. Start by writing down every recurring service used for work. Include subscriptions that are billed annually, free services that have become important to your workflow, and tools that are only used occasionally.
- List the tools you currently use. Include AI, design, writing, project management, communication, storage, scheduling, ecommerce, CRM, website, and automation software.
- Record the plan and billing cycle. A monthly plan and an annual plan should not be compared without normalizing the time period.
- Identify the job each tool performs. If two subscriptions perform substantially similar work, flag the pair for a closer review.
- Separate essential tools from optional tools. A tool can be useful without being essential to the business.
- Check the actual workflow before changing anything. Features, limits, integrations, data, history, and team habits can matter more than the headline subscription price.
Find Overlapping Software Tools
Software overlap happens when multiple subscriptions solve substantially similar problems. Common examples include two general-purpose AI assistants, several project management platforms, multiple design applications, or separate writing tools that are used for the same work.
Overlap does not automatically mean that one subscription should be cancelled. Different tools can have different strengths, models, integrations, limits, or workflows. The purpose of an audit is to make the duplication visible so you can decide whether the additional subscription still earns its place.
Lean Stack Builder therefore labels these findings as possible overlap and spend to review rather than presenting a cancellation as an automatic recommendation.
How Lean Stack Builder Estimates Potential Savings
The savings figure is deliberately conservative. When overlapping tools are detected, the calculator does not simply add every possible saving together. The same subscription can appear in more than one overlap, so adding every pair could exaggerate the result.
Instead, the tool uses the largest single detected overlap opportunity and applies a cap relative to the selected monthly spend. The result should be treated as a potential saving to review, not a guaranteed amount of money you will save.
Actual costs can differ because software prices change, plans have different limits, taxes may apply, regional pricing can differ, and some products charge according to seats, usage, or billing terms.
Build a Lean Software Stack
A lean software stack is not necessarily the stack with the fewest apps. It is a stack where each recurring tool has a clear job and the combined setup is appropriate for the work being done.
For a freelancer, that might mean keeping a small group of tools for AI, project management, documents and storage, then adding specialist software only when a real workflow requires it. A content creator may need design and newsletter software, while an ecommerce business may need an online store and customer management. There is no universal number of tools that every business should use.
The Build My Lean Stack section helps you explore a starting setup by role and need. It separates essential tools from optional tools and provides free-first alternatives where available.
Who Is This Software Stack Audit For?
Lean Stack Builder is designed for people who manage their own software decisions rather than large procurement departments. It can be useful for:
- Freelancers reviewing recurring business subscriptions
- Content creators managing AI, design, video, and newsletter tools
- Solo business owners trying to control SaaS spending
- Ecommerce businesses reviewing store and supporting software
- Small agencies checking for duplicated tools across workflows
- Online businesses building a practical software stack from scratch
Example: Auditing an AI-Heavy Stack
Imagine a freelancer paying for ChatGPT, Claude, Perplexity, and a premium writing assistant. The combined subscriptions may have different reasons behind them, but an audit can reveal that several products are being used for research, drafting, rewriting, and general AI work.
The correct next step is not automatically to cancel one. Instead, compare the tasks you actually perform, the features you use, the limits you encounter, and whether each subscription has a distinct role. If two tools are rarely differentiated in real work, that is a stronger reason to review the additional subscription.
Why a Lean Stack Can Be Better Than a Bigger Stack
More software can create more capability, but it can also create more logins, recurring charges, duplicated features, disconnected information, and decisions about which tool to use. A lean stack reduces that complexity when specialist software is not providing enough additional value to justify its cost.
The goal is not to eliminate useful software. The goal is to make every recurring subscription easier to explain: what job does it own, who uses it, how often is it used, and what would change if it were removed?
Pricing and Methodology
Prices displayed by Lean Stack Builder are reference paid-plan prices for supported tools. They are not quotes and may differ from the amount you actually pay because of country, taxes, promotions, annual billing, seat counts, usage limits, or changes made by the software provider.
Official plan links are provided so you can verify current pricing and features before making a subscription decision. Free alternatives are presented as options to investigate, not as automatic replacements.
The calculator performs its core calculations in the browser. It is intended as a planning and comparison tool, not as financial, procurement, legal, or security advice.
Frequently Asked Questions About Software Stack Audits
What is a software stack audit?
A software stack audit is a review of the software and subscriptions used by a person or business. It looks at cost, purpose, overlap, usage, and whether each tool still fits the current workflow.
What is a software stack cost calculator?
A software stack cost calculator combines the recurring prices of selected tools so you can see the monthly and yearly cost of the stack in one place. Lean Stack Builder also highlights potential overlap between supported tools.
How can freelancers reduce software subscription costs?
Start by listing every subscription, identifying the job each tool performs, checking for duplicated capabilities, and reviewing unused or low-frequency subscriptions. Compare free tiers and lower-cost plans only after checking whether they still support the workflow you need.
Does software overlap mean I should cancel a tool?
No. Overlap is a reason to review a subscription, not proof that it should be cancelled. Two products can provide different features or workflows even when their broad categories are similar.
Are the prices shown by Lean Stack Builder guaranteed?
No. The displayed figures are reference prices for supported plans. Providers can change pricing, billing terms, features, limits, taxes, and regional availability.
Can I audit a custom software subscription?
Yes. You can enter a custom tool name when it is not included in the supported-tool list. Custom tools are not assigned a reference price by the calculator unless a supported profile or database entry exists.
Is Lean Stack Builder free?
Yes. The Lean Stack Builder is available as a free browser-based tool for auditing a software stack and exploring a lean starting setup.
