Can Seobility be vibe coded?
Crawl an owned site, track selected keywords, and organize remediation tasks
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Seobility, crawl an owned site, track selected keywords, and organize remediation tasks. The hard boundary is hosted crawling, keyword data, backlink monitoring, reports, and support, plus crawl scale, rule depth, and operational polish.

medium editorial confidence
Buildability by layer
Screens, forms, and focused interactions
The repeatable job the product performs
Availability and legality of required data
Uptime, queues, support, and maintenance
Security, compliance, and user confidence
The achievable core
- Crawl a user-owned site, track selected keywords, inspect HTML and rendered pages, explain prioritized issues, organize remediation tasks, and export a reproducible audit.
- Automate a bounded research or reporting workflow using permitted data sources.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- hosted crawling, keyword data, backlink monitoring, reports, and support
- massive hosted crawl capacity
- proprietary scoring
- continuous monitoring
- Reliability at the vendor's scale is an operations problem, not a prompt.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.
Why people still pay
People still pay for Seobility because a crawler is buildable; professionals pay for years of edge-case handling and reports they can trust with clients. The recurring cost buys robots handling, rendering, canonicalization, deduplication, crawl traps, rule maintenance, scheduling, storage, and false positives, not just the visible interface.
Reliability at the vendor's scale is an operations problem, not a prompt.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
The useful dataset is owned, accumulated, or expensive to reproduce.

Build brief — a focused alternative to Seobility
Context
**Seobility** — Crawl an owned site, track selected keywords, and organize remediation tasks. It currently costs $49.9/mo.
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Seobility, crawl an owned site, track selected keywords, and organize remediation tasks. The hard boundary is hosted crawling, keyword data, backlink monitoring, reports, and support, plus crawl scale, rule depth, and operational polish.
This brief describes a focused, single-operator replacement for the part of Seobility that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Crawl a user-owned site, track selected keywords, inspect HTML and rendered pages, explain prioritized issues, organize remediation tasks, and export a reproducible audit.
Automate a bounded research or reporting workflow using permitted data sources.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Python 3.12.
Playwright browsers.
Permission to crawl the target site.
Local disk space.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a personal replacement for Seobility in an empty repository.
Use Python 3.12, FastAPI, SQLite, Playwright, and an HTMX interface; do not offer alternative stacks.
The core loop is: crawl a user-owned site, track selected keywords, inspect HTML and rendered pages, explain prioritized issues, organize remediation tasks, and export a reproducible audit.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Require an explicit ownership or permission acknowledgement before a crawl starts.
Respect robots.txt, rate limits, canonical URLs, nofollow, redirects, and a configurable URL cap.
Collect status, title, description, headings, canonical, robots, links, images, structured data, and rendered text.
Detect duplicates, orphan candidates, broken links, redirect chains, missing metadata, and indexability conflicts.
Show every issue with affected URLs, evidence, severity, and a concrete remediation note.
Export crawl data and issues to CSV plus a self-contained HTML report.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out crawling sites without permission.
Deliberately leave out web-scale backlink or keyword datasets.
Deliberately leave out automated changes to production websites.
Finish by running the tests and listing the exact commands used.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Hosted crawling, keyword data, backlink monitoring, reports, and support.
Massive hosted crawl capacity.
Proprietary scoring.
Continuous monitoring.
Reliability at the vendor's scale is an operations problem, not a prompt.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
What you still own after launch
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Risk
**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.
Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.
