Overview

What this migration involves

Cronberry's most significant migration barrier is the absence of a publicly documented REST API. The platform's GitHub repositories contain only client-side webpush SDKs, not a full data export interface. We handle this by coordinating with Cronberry's internal tools or direct database access, extracting structured CSV or JSON dumps of Contacts, Campaigns, Segments, and Templates before migration begins. Cronberry's contact deduplication is unreliable, producing duplicate records for the same physical contact; we identify and merge probable duplicates using name, email, and phone matching before importing into Twenty. Smart Segments built from field-value conditions cannot be exported as reusable schemas, so we reverse-engineer each segment by querying membership and documenting the implied conditions for manual rebuild in Twenty's grouping system. We migrate Contacts with tag associations, Companies, Deals, Opportunities, Activities (event logs), Users, and message Templates. Landing Pages, Forms, Workflows, and automations do not migrate; we deliver a written inventory of these for the customer's admin to rebuild in Twenty. Twenty CRM is an open-source, API-first CRM with self-hosting capability, approximately 40,000 GitHub stars, and active development. Early-stage platform users report occasional stability issues which the core team has acknowledged and is actively addressing.

Why teams make this switch

Two sides of the same decision

Leaving

Cronberry logo

Cronberry

What's pushing teams away

  • Recent UI overhaul shipped without user training or documentation, leaving teams unable to locate features and wasting money on leads they cannot manage.
  • Repeat-contact detection and contact naming conventions are described as confusing and broken by multiple reviewers, creating duplicate records in the CRM.
  • Facebook and Google Ads remarketing are absent, forcing teams to manage paid acquisition and retargeting in separate platforms.
  • Customer support responsiveness drops significantly after purchase according to negative reviews citing unanswered calls and emails.
  • No publicly documented API limits or bulk export capability, making data portability a manual and error-prone process.

Choosing

Twenty CRM logo

Twenty CRM

What's pulling them in

  • Top open-source CRM on GitHub with 40.6K stars, giving teams full source code access and infrastructure ownership without per-feature licensing surprises.
  • Free self-hosting under AGPL-3.0 means unlimited users and custom objects for the cost of cloud infrastructure alone, typically $20–100/month.
  • Pricing page explicitly mocks competitors for charging add-on fees for API access, webhooks, and workflows — transparency that resonates with RevOps teams burned by Salesforce.
  • Unlimited custom objects and fields with no price impact, letting teams shape the data model to their business rather than forcing business into rigid schemas.
  • Modern TypeScript/React/PostgreSQL stack means developer-led teams can extend, self-host, or integrate without fighting legacy architecture.

Object mapping

How Cronberry objects map to Twenty CRM

Each row shows how a Cronberry object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Cronberry

Contact

maps to

Twenty CRM

Person

1:1
Fully supported

Cronberry Contact records map to Twenty's Person object, which represents individual contacts. We preserve email, phone, name fields, and custom field values. Cronberry's tag associations transfer to Twenty as custom text or multi-select fields (chosen during scoping). The critical pre-migration step is deduplication: Cronberry's unreliable repeat-contact detection means a single physical contact may exist as multiple records. We identify probable duplicates by matching on name, email, and phone, present a deduplication report to the customer, and merge before importing into Twenty to avoid contaminating the new workspace.

Cronberry

Company

maps to

Twenty CRM

Company

1:1
Fully supported

Cronberry Company records map directly to Twenty's Company object. Field-level mapping is required because Cronberry's company schema varies by implementation and may include custom properties. We extract company name, domain, address fields, and any custom fields, then map them to Twenty's Company fields. Company is imported before Person records so that the relationship can be resolved during Person import via company domain matching.

Cronberry

Deal

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Cronberry Deals map to Twenty's Opportunity object. Each Opportunity receives a name, amount, close date, and stage. The stage mapping is designed during scoping based on Cronberry's deal pipeline stages. Closed-Lost and Closed-Won reasons from Cronberry custom fields migrate to Opportunity custom fields for audit and reporting continuity.

Cronberry

Campaign

maps to

Twenty CRM

Custom Object or Opportunity grouping

lossy
Fully supported

Cronberry Campaigns carry channel information (Email, SMS, Push, WhatsApp), timing rules, and target segment assignments. Twenty does not have a native Campaign object, so we map Campaigns to either a custom Campaign object (created via Twenty's custom object API) or to Opportunity groupings by campaign. Campaign-channel associations are documented in the mapping spec for the customer to configure manually in Twenty's channel setup. Campaign timing rules do not migrate as automations.

Cronberry

Smart Segment

maps to

Twenty CRM

Custom Field or Grouping

lossy
Fully supported

Cronberry Smart Segments are defined by conditional rules against contact field values. These rules are not exported as reusable schemas. We reverse-engineer segment membership by querying which contacts belong to each segment, then derive the implied conditions from the contact field data and document them. In Twenty, segments can be modeled as custom filter views or as tag-based groupings via the API. We deliver a written segment reconstruction guide specifying the conditions for each original Cronberry Smart Segment so the customer's admin can rebuild them in Twenty's workspace.

Cronberry

Event Log / Behavioral Tracking

maps to

Twenty CRM

Activity

1:1
Fully supported

Cronberry tracks behavioral events (opens, clicks, push interactions) as Event Logs. These map to Twenty's Activity records with activity type, timestamp, and related Person or Company. Event schema may require field mapping because behavioral event properties differ between platforms. We extract event type, event date, and any associated contact reference, then map to Twenty Activity with the activity type field set to reflect the original Cronberry event category.

Cronberry

User / Agent

maps to

Twenty CRM

Workspace User

1:1
Fully supported

Cronberry User and agent records map to Twenty workspace members. We extract user name, email, and role where available. Role and permission structures differ significantly between platforms; we migrate basic user identity and defer permission model configuration to the customer's admin post-migration. Active/inactive status is preserved.

Cronberry

Template (Email, SMS, Push)

maps to

Twenty CRM

Template

1:1
Fully supported

Message templates with personalization variables are migratable. We extract template content and variable placeholders from Cronberry's template storage. Rich formatting (HTML in email templates, character encoding in SMS templates) may require adjustment for Twenty's template format. We deliver a template migration report listing each template's content, variable placeholders, and channel type for manual import into Twenty's template system.

Cronberry

Channel Configuration

maps to

Twenty CRM

Channel Configuration

lossy
Fully supported

Cronberry's multi-channel setup stores channel credentials and API keys for Email, SMS, Push, and WhatsApp. These credentials (API keys, sender IDs, domain authentication records) cannot be exported for security reasons and must be reconfigured manually in Twenty's channel settings. We document the channel types active in Cronberry and provide a setup checklist for the customer's admin to configure in Twenty.

Cronberry

Custom Object (Form-level)

maps to

Twenty CRM

Custom Field

lossy
Fully supported

Cronberry form-level custom fields extend the Contact and Company schemas. These map to Twenty custom fields on the Person and Company objects. We extract the field definitions (name, type, options for picklists), create corresponding custom fields in Twenty's schema via the API, then migrate the field values during the Person or Company import phase. Custom field types are mapped to Twenty field types (text, number, date, select, multi-select) during scoping.

Pair-specific challenges

  • Cronberry has no public REST API for bulk export

    Cronberry does not publish API documentation for programmatic data access. The GitHub repositories contain only client-side webpush SDKs, not a full data export interface. We handle this by coordinating with Cronberry's internal tools or requesting direct database access, extracting structured CSV or JSON dumps of Contacts, Campaigns, Segments, and Templates before migration begins. This coordination step extends the project timeline compared to platforms with open APIs and is the primary source of timeline risk for this migration pair.

  • Smart Segment logic cannot be exported directly

    Cronberry's Smart Segments are defined by conditional rules against contact field values, but these rules are not exported as a reusable schema. We reverse-engineer segment membership by querying which contacts belong to each segment, deriving the implied conditions from the contact data, and documenting them for manual rebuild. This approach is accurate for simple field-value conditions but may lose nuance for complex multi-condition segments built with AND/OR logic. We deliver a written segment reconstruction guide and validate membership against the source during QA.

  • Cronberry's contact deduplication is unreliable

    Multiple reviewers consistently report that Cronberry's repeat-contact detection is broken and contact naming conventions are confusing. This means a single physical contact may exist as multiple records in Cronberry, inflating contact counts and fragmenting behavioral history. During migration scoping, we identify probable duplicates by matching on name, email, and phone, present a deduplication report to the customer before import, and merge duplicates in the source before migrating. Without this step, duplicated contacts enter Twenty and contaminate the workspace from day one.

  • Twenty CRM is an early-stage platform with stability reports

    Users on Twenty's Discord and community channels have reported stability issues including views falling apart, incorrect values appearing in saved views, and performance degradation with larger contact volumes (600+ leads cited). The Twenty core team has acknowledged these issues publicly and shifted engineering priority toward quality, stability, and bug fixes. We flag this during scoping so customers have realistic expectations. We recommend a sandbox migration to validate stability before production cutover and advise against migrating large engagement history in a single batch.

  • Workflows and automations do not migrate to Twenty

    Cronberry campaign workflows built with the visual workflow builder cannot migrate to Twenty because Twenty's automation capabilities are API-first and do not yet include a visual workflow builder equivalent. We do not rebuild workflows as code. We deliver a written inventory of every active Cronberry automation with its trigger, conditions, actions, and channel assignments, so the customer's admin can evaluate manual alternatives or custom development in Twenty. Form definitions migrate as schema only; visual layout cannot be preserved.

Migration approach

Six steps for a successful Cronberry to Twenty CRM data migration

  1. Export coordination with Cronberry

    We initiate data export coordination with Cronberry's support team to obtain structured data dumps. Because Cronberry lacks a public API, we work with their internal export tools or direct database access where available. We request CSV or JSON exports of Contacts, Companies, Deals/Campaigns, Segments, Templates, and User records. This step is the primary timeline variable; we begin coordination during scoping and continue until export files are secured. We validate the export schema against the documented Cronberry data model and flag any missing fields immediately.

  2. Data audit and deduplication

    We run a full data quality audit on the exported files. We identify probable duplicate contacts by matching on name, email, and phone across the Contact export, generate a deduplication report showing the merge candidates, and present it to the customer's admin for approval before any merge action. We also identify Smart Segment membership by querying the segment-to-contact relationships in the export data, derive the implied field-value conditions for each segment, and document them for reconstruction. We flag any missing custom fields, incomplete records, or data anomalies at this stage.

  3. Twenty workspace schema design

    We design the destination schema in Twenty. This includes creating custom fields on Person and Company objects to receive Cronberry custom properties, creating a custom Campaign object (via Twenty's custom object API) if campaign migration is in scope, configuring workspace-level field types and picklists to match Cronberry's data, and designing the Opportunity schema with stage mapping from Cronberry's deal pipeline. We deploy schema changes to a Twenty sandbox or development workspace first for validation.

  4. Sandbox migration and reconciliation

    We run a full migration into a Twenty sandbox workspace (or development instance) using production-like data volume. The customer's admin reconciles record counts (Contacts imported, Companies imported, Deals imported, Activities imported), spot-checks 25-50 random records against the Cronberry source, and validates that deduplication merged correctly. Any mapping corrections, missing field additions, or custom object schema adjustments happen in this phase before production migration begins.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Companies (imported first to establish the organizational hierarchy), Persons (with deduplication applied, Company relationship resolved via domain matching), Opportunities (with Person and Company lookups resolved), Activities (event logs mapped to Twenty Activity records), Segments (documented for manual rebuild in Twenty), Templates (delivered as a content migration report for manual import), and Users (mapped to Twenty workspace members). Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and automation inventory handoff

    We freeze Cronberry writes during cutover, run a final delta migration of any records modified during the migration window, then enable Twenty as the system of record. We deliver the Smart Segment reconstruction guide, the Workflow and automation inventory document, and the channel setup checklist to the customer's admin. We support a one-week hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild Cronberry workflows or automations inside the migration scope; that is documented for manual rebuild or a separate engagement.

Strengths

  • Multichannel outreach in a single subscription covers Email, SMS, Push, WhatsApp, and In-App messaging.
  • Lowest entry price among comparable marketing automation platforms at $25/month usage-based.
  • Drag-and-drop form and landing page builders require no coding to create lead capture assets.
  • Lead management with caller assignment and follow-up tracking consolidates sales engagement workflows.

Weaknesses

  • No publicly documented REST API means migration must rely on manual exports or undocumented endpoints.
  • Recent UI redesign shipped without training materials, creating a known onboarding gap for existing customers.
  • Contact deduplication and naming conventions are unreliable, leading to duplicate record issues post-import.
  • Absence of Facebook and Google Ads remarketing integration forces teams to split paid media management across platforms.
  • Customer support responsiveness declines sharply after purchase based on negative review patterns.

Strengths

  • AGPL-3.0 open-source license with full source code on GitHub — no vendor lock-in, no sunset risk.
  • Unlimited users and unlimited custom objects on self-hosted, with no feature gating based on headcount.
  • REST and GraphQL APIs available on all paid tiers, not locked behind an enterprise add-on fee.
  • MCP server and webhooks shipped as standard features, not premium upgrades.
  • Modern PostgreSQL-backed data model that developer teams can query, extend, and self-host.

Weaknesses

  • Recent v1.0 release means limited production hardening compared to CRMs with multi-year operational track records.
  • No native email sequencing or sales engagement tools — follow-up cadences require a separate platform.
  • No native two-way email sync or inbox integration, requiring third-party connectors for full activity logging.
  • Self-hosting 'free' pricing hides real infrastructure and DevOps costs that stack up over time.
  • Workflow automation is functional but lacks the complexity needed for sophisticated multi-step sales motions.

Most migrations land between three and five weeks for accounts under 15,000 Contacts with clean exports and straightforward segment logic. Migrations with large contact volumes (over 50,000), extensive Smart Segment reverse-engineering requirements, degraded export access through Cronberry support, or custom object schemas move to eight to twelve weeks. The primary timeline variable is Cronberry's export coordination; platforms with open APIs complete scoping and export in days, while Cronberry's undocumented access requires direct coordination that can extend discovery by one to three weeks.
