PandaCodeGen
Next.js Development Agency

The tool your business needs does not exist, so you are running it on spreadsheets.

We design SaaS platforms, internal dashboards and AI-enabled tools around how you actually work, what they have to connect to, and what gets in the way. All of that comes out of one short call. Who gets the code, which licences apply, who owns the IP, what support you get and how it is handed over are all in the written proposal.

See What We Build

Tell us the idea or show us the tool you use now. We will tell you what it would take and what it costs. The price comes in writing.

PandaCodeGen scopes and builds custom software, SaaS platforms, dashboards, and internal tools with technologies such as Next.js, TypeScript, and Supabase. Your written quote says what gets built, the price, the dates, what support you get, and that the code, the accounts and the rights are yours at the end. Work starts at $1,500 at a fixed price, and there is no minimum project size.

What We Build

What Our Next.js Development Agency Builds

These capability examples help frame discovery. They are not claims about a completed client project or a promise that every feature belongs in your scope.

SaaS Platforms

Project management tools
CRM & client portals
Multi-tenant auth with role-based access
Stripe/payment gateway integration

Internal Tools

Custom dashboards, admin panels, and workflow automation that replace spreadsheets and manual processes with real-time, automated systems.

Operations & logistics dashboards
Inventory management systems
Employee onboarding portals
Real-time analytics & reporting

How We Build

From Idea to an Agreed Delivery Plan

The work runs in stages you review as we go. Your quote has the dates and what has to be working at each one.

01
Phase 1

Discovery

We map what you need, how people will use it, what constrains it and what the options are. The scope then records what we assumed, what it depends on, the milestones, and how you sign it off.

02
Phase 2

Prototype & Validate

Where useful, we test important workflows or technical risks before committing to the full implementation path.

03
Phase 3

Implementation

We build the approved features and integrations in reviewable increments using the architecture selected for the project.

04
Phase 4

Verification & Handover

We run the agreed checks, prepare deployment and documentation, and complete support, access, licensing, and handover steps stated in the proposal.

Growth Cap

The No-Code Ceiling

These are the problems founders and businesses hit when they try to scale on no-code platforms:

Unclear Commercial Assumptions

A proposal should separate discovery, implementation, third-party services, change requests, and ongoing support so the cost model can be evaluated before commitment.

Architecture Without a Load Model

Capacity depends on user behavior, data volume, integrations, and failure handling. Those assumptions should be documented and tested against the approved requirements.

Incentives Hidden in the Contract

Fixed-price, hourly, and milestone models each have trade-offs. The selected model, change process, and acceptance criteria should be explicit in the written proposal.

Portability and Access Gaps

Platform exports, repository access, credentials, licensing, and handover vary. Review them before choosing an implementation path or vendor.

Technology Chosen Before the Problem

Technical due diligence examines architecture, operations, security, and maintainability. The stack should follow the product constraints and evidence, not a generic label.

AI Added Without Evaluation

AI features need suitable provider APIs, data controls, test cases, fallback behavior, and monitoring. Discovery identifies whether native integration is appropriate.

After the build

Most businesses cannot say which channel their last ten customers came from

The reporting layer is where most builds stop short. The site ships, the leads arrive, and nobody can say whether the spend is going to the channel that produces them. We build the part that answers that, because a dashboard you have to interpret is not a report.

The lead arrives as an email

A form fires a notification, nobody records where that visitor came from, and by the time somebody reads it the source is gone. The CRM has a lead source field and it is empty on most records.

GA4 answers a different question

It reports sessions and events. You asked which spend produced revenue. Getting from one to the other is a configuration project, not a setting, which is why the tab stays closed.

Every platform claims the same sale

Meta counts it, Google counts it, and the CRM counts it. The totals never reconcile, so eventually nobody trusts any of them and the decision gets made on instinct.

What we build instead

  • Lead source captured at the moment of the enquiry and written onto the CRM record, so it survives past the notification email.
  • One view showing leads by channel next to what that channel cost and what it produced, rather than three tools that disagree.
  • A scheduled email report, because the dashboard nobody logs into is the same as no dashboard.

Where this is already running. Our enterprise operations platform reports lead volume by channel across search, social, paid ads, AI and LLM referrals, and direct referral, in one place, across twelve reporting modules.

What it does not do. This reports on data you already have. It does not recover attribution for traffic that arrived before the tracking existed, and no model resolves the buyer who saw an ad, asked a friend, then typed your name into Google. Anyone promising that is selling you a guess with a confidence interval printed on it.

No-Code vs Custom Coded

Compare what each one limits, what it locks you into, and what it costs to run.

Capacity Planning
No-CodeCapacity and scaling controls depend on the selected platform and plan
CustomLoad profile, capacity targets, and scaling controls are defined during discovery
Repository & Rights
No-CodeExport, access, and licensing terms vary by platform
CustomWho gets the code, which licences apply, when the IP transfers, and how it is handed over. All in the proposal
Performance
No-CodeResults vary with templates, scripts, content, and integrations
CustomWe agree the baseline, the test conditions and what counts as done before anyone builds
Operating Costs
No-CodeSubscriptions, add-ons, and usage charges require a current account review
CustomHosting and service estimates are itemized against the proposed architecture
Customization
No-CodeChanges are limited by supported extension points and plan features
CustomCustom workflows can be designed within the agreed scope and dependencies
AI Integration
No-CodeOptions depend on available APIs, add-ons, and data controls
CustomIntegrations get designed around the data you approved, the security you need, and how it will be judged

H

Delivery accountability

Know the Team and Responsibilities Before Kickoff.

Your written quote names who does the work, who you talk to, how often you review it, and whether anyone outside our team is involved.

One call works out how it would be built and what could go wrong. The price, the dates, who builds it and what support you get all go in writing.

Custom Scope Review

Start with evidence. Put the agreement in writing.

The call is where we work out what you have, what you want, and what is in the way. Nothing is a commitment until it is in your written quote. For most projects that quote is a short document you accept by email. Regulated or complex work gets a fuller agreement.

Diagnostic first

We begin with the URL, stack, content, integrations, analytics, and operational constraints. Automated audit output is treated as an estimate to investigate, not proof of revenue loss or a guaranteed business result.

Evidence before outcomes

Any speed number, ours or anyone else's, is a snapshot of one day. Your quote names which pages we test, on what device, with which tool, and what counts as passing.

Scope before certainty

The proposal says what is included, what is not, what we need from the client, what it depends on, and how changes get approved.

Targets need a method

If there is a performance or visibility target, we write down how it gets measured and what happens if it is missed.

Terms belong in the proposal

Payment milestones, support coverage, ownership, licenses, handover, and out-of-scope work are confirmed in writing.

What should be documented before work starts

Use the call to get the facts. Use the written quote for the promises.

Spec Sheet

A reviewable build blueprint for each project

Before we build, you get a written plan of how it works, what it connects to and who is responsible for what. The quote is what counts.

Scope and Commercial Review

Choose a planning path. Confirm the project in writing.

These are starting points for the first conversation, not quotes. Your written quote has the real price, the dates, what is included, what support you get and who owns the code.

Before Discovery

Working assumptions

We still have to look at the features, the integrations, the content, what could go wrong in the migration, and what it depends on.

After Discovery

Written proposal

The approved scope is where we write down what we committed to, what we assumed, what is excluded, the milestones, and how you sign it off.

FAQ

Frequently Asked Questions

Straight answers. No sales fluff.

The line sits in a different place on an application, so it is worth setting before we build. Content, labels, copy, prices, options in a dropdown and anything else that is data goes in an editor or an admin screen your team controls. Business rules, permissions, new screens and anything that changes how the system behaves is development work, quoted before it starts. We agree that list with you during scoping and write it into the handover, so nobody discovers the boundary during an emergency.

A website takes 2 to 4 weeks. An app takes longer. The last one we published, an operations platform with staff logins, payments and attendance tracking, has been in continuous development for ten months. You get a written plan with dates before you pay anything, so the timeline is agreed rather than guessed.

Custom apps are quoted after one short call, and the quote is fixed. Agencies that bill by the hour sell you hours. We sell you the finished app. Our published tiers start at $1,500 and the largest starts at $5,000, and anything bigger is quoted after a call. You pay 30% to start and 70% when it's done. No hourly billing, no monthly retainer, and your written quote has the exact figure.

Yes. Chat, reading documents, search, or writing from your own data, built into your app instead of rented from another tool with a per-seat fee. We check your data is good enough and your privacy rules allow it, then write down exactly what the feature does before we build it.

We rebuild it in real code, quoted after a call and fixed in writing. Your current app keeps running while we build. On launch day you switch over, and if anything is wrong you switch straight back. You stop paying the no-code platform the day the new app is accepted.

Yes, all of it. The code, the design files, the editor, the documentation and the accounts it runs on are handed to you under your own name. Some agencies keep the code on their accounts, so you end up renting your own product. Ask any provider what you'll actually hold on day one. With us it's everything, and it's written into the contract.
