Bigin bigin.comCan AI replace Bigin?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Bigin, run a small-business pipeline with contacts, activities, and simple workflows. The hard boundary is zoho ecosystem, telephony, forms, integrations, and mobile apps, plus integrations, data quality, and workflow lock-in.

| Plan | Monthly | Billed yearly | What you get |
|---|---|---|---|
| Free | Free | Free | 1 user and 500 total records |
| Express | $9 | $7/mo | 50,000 records; no user-count limit (each user requires a license) |

Hidden costs: Local taxes may be added despite contradictory wording on the page; paid plans charge for every user. Add-ons are sold separately in the Bigin Store. Annual downgrades can create account credits rather than cash refunds.
02Could AI build it for you?
The core job: Manage contacts and companies for a small business, move opportunities through a pipeline with simple workflows, log interactions and activities, and surface the next action.
What a working version needs:
- Docker
- PostgreSQL
- self-hosted server
- optional email API credentials
Editorial comparison targets the Express plan and a personal or very small-team CRM DIY substitute. Recheck price before merge.
03What you'd give up
- Zoho ecosystem, telephony, forms, integrations, and mobile apps
- automatic email and calendar capture
- data enrichment
- large integration ecosystem
- enterprise reporting
People still pay for Bigin because CRM value compounds as the system becomes the shared memory of every customer interaction and embeds itself in the rest of the stack. The recurring cost buys deduplication, permissions, imports, sync, enrichment, email capture, automations, backups, and audit history, not just the visible interface.
04Free and cheaper alternatives
A traditional CRM that actually lets you change the data model; polished enough, but still your server.
Versus paying: EspoCRM is much heavier to configure and administer than Bigin’s deliberately simple small-business pipeline.
espocrm.com →A clean leads-and-deals board with notes, tasks and email; Frappe underneath means a real server, not a toy.
Versus paying: Frappe CRM needs considerably more configuration to reach Bigin’s ready-made pipeline and workflow experience.
frappe.io →A real two-seat CRM for free; 1,000 contacts is where the upsell starts counting.
Versus paying: HubSpot’s free tier puts much of the useful workflow automation behind paid hubs and surrounds the simple pipeline with a larger upsell-heavy suite.
hubspot.com →A Laravel sales pipeline with leads, contacts and email; glossy enough, but it still wants a PHP stack.
Versus paying: Krayin is less mature and less plug-and-play around everyday email, calendar, mobile, and workflow use than Bigin.
krayincrm.com →A modern pipeline CRM with custom objects, views and mailbox sync; the subscription becomes a Compose file.
Versus paying: Twenty’s ready-made sales automation and small-business onboarding are thinner than Bigin’s out-of-the-box workflow.
twenty.com →A full hosted pipeline for unlimited users, provided CRM is the only Odoo app you marry.
Versus paying: Odoo is substantially more complex than Bigin, and the one-app-free bargain ends when the business needs another Odoo module.
odoo.com →A full little CRM for three users and 5,000 records; the wider Zoho maze is optional.
Versus paying: Zoho’s free plan is capped at three users and withholds the workflow automation depth that makes Bigin useful beyond a bare pipeline.
zoho.com →A clean three-user pipeline with email and mobile apps; useful automation starts asking for rent.
Versus paying: Freshsales Free covers a basic pipeline but withholds multiple pipelines, richer workflows, and sales sequences that Bigin users may rely on.
freshworks.com →05The build prompt
Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version.
Build a personal replacement for Bigin in an empty repository. Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, and Docker Compose; do not offer alternative stacks. The core loop is: manage contacts and companies for a small business, move opportunities through a pipeline with simple workflows, log interactions and activities, and surface the next action. 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. Create contacts, companies, opportunities, notes, tasks, and configurable pipeline stages. Add fast global search, duplicate detection, merge, CSV import, and CSV export. Provide a chronological interaction timeline with manual email and meeting logging. Implement saved views, filters, owner assignment, and a next-action dashboard. Add role-based access, an immutable activity log, backups, and a recovery command. Seed a realistic demo workspace and document field mapping for imports. 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 automatic mailbox ingestion. Deliberately leave out commercial enrichment databases. Deliberately leave out enterprise forecasting, integrations, and compliance. Finish by running the tests and listing the exact commands used.
