The 30+ apps in our AppZ catalog (and what each replaces)

The “self-hosted apps” rabbit hole is a long one. There are thousands of open-source projects that could replace a SaaS subscription. Most of them shouldn’t, because they don’t actually work in production, or they work but the maintenance load is too high, or they technically work but no real business has used them at scale.

This is the shorter list — the apps in our AppZ catalog, ready to deploy into a customer’s isolated environment, organized by what they replace. Each one is here because we’d run it on our own stack and we have a path to operating it for someone else. Anything not on this list, we either haven’t fully battle-tested or haven’t found the right fit for yet.

Business operations

The category most businesses can’t avoid touching.

ERPNext — full ERP. Accounting, inventory, HR, manufacturing, CRM. The flagship Frappe app and the foundation of most SystemZ vertical products. Replaces NetSuite, SAP Business One, Odoo Enterprise.
Frappe CRM — native to your Frappe site. Lead and opportunity management with automation. Replaces HubSpot CRM, Pipedrive at the small-to-mid scale.
Frappe Helpdesk — email and portal-based ticketing. Native to the Frappe site, no separate login. Replaces Zendesk, Freshdesk for non-live-chat workflows.
InvoiceNinja / Crater — focused invoicing tools for businesses that don’t need the full ERP. Replaces FreshBooks, Wave.
Akaunting — full accounting for businesses with separate accounting needs. Replaces Xero, QuickBooks at the small scale.
FrappeHR — HR, payroll, leaves, performance reviews. Native to the Frappe site. Replaces BambooHR, Personio.

Customer support and engagement

For when email tickets aren’t enough.

Chatwoot — omnichannel inbox: live chat on your website, WhatsApp, Instagram DMs, email, SMS — all in one queue. The most actively-deployed support app on AppZ. Replaces Intercom, Drift, Tidio.
Typebot — chatbot builder. Visual flow editor, deployable as a website widget or WhatsApp bot. Replaces Landbot, ManyChat for conversational lead capture.
EasyAppointments — booking and scheduling. Replaces Calendly, Acuity at small-business scale.
MiroTalk — video meetings, no account required for guests. Browser-based, P2P. Replaces Zoom for client-facing meetings under 10 participants.

Analytics and marketing

The category where SaaS pricing scales with success.

Frappe Insights — dashboards and BI on your Frappe site. Native to the data, no separate login or ETL. Covers most internal-reporting needs.
Umami — privacy-first website analytics. Page views, sources, conversion events. Replaces Google Analytics at the marketing-measurement layer.
PostHog — product analytics. Event tracking, funnels, session replay, feature flags. Replaces Mixpanel, Amplitude. Heavier than Umami; pick based on whether you need event-level depth.
Superset — enterprise BI for when Frappe Insights isn’t enough. Multi-source dashboards, deep SQL access. Replaces Looker, Tableau.
Mautic — email marketing automation. Drip campaigns, lead scoring, contact segmentation. Replaces ActiveCampaign, Mailchimp at the SMB scale.
Postiz — social media scheduling across LinkedIn, X, Facebook, Instagram, Nostr. Replaces Buffer, Hootsuite.
Formbricks — surveys and feedback forms. Replaces Typeform, SurveyMonkey for embedded forms.

Collaboration and knowledge

For team operations and customer-facing docs.

Frappe Wiki — wikis and docs native to your Frappe site. Best for internal knowledge management when you already run Frappe.
Outline — Notion-style team docs. Block editor, deep linking, real-time collaboration. Replaces Notion for businesses unwilling to host data on a third-party SaaS.
Frappe Gameplan — Jira / Linear alternative for Frappe-native project management. Native to the site.
OpenProject — heavier project management with Gantt charts, agile boards, and waterfall planning. Replaces MS Project, Asana for large operations.
Rocket.Chat — Slack alternative. Channels, threads, integrations, video calls. Replaces Slack, Microsoft Teams.
Nextcloud — file storage, calendar, contacts, document collaboration. Replaces Google Workspace, Dropbox.

Automation and AI

The category that has changed fastest in the last 18 months.

n8n — visual workflow automation. 400+ integrations, custom JavaScript nodes. The most-deployed automation tool on AppZ. Replaces Zapier, Make at the per-task pricing tier.
Activepieces — simpler n8n alternative for businesses that want lighter automation. Open-source Zapier UX.
LiteLLM — unified LLM gateway. One API endpoint that routes to any major provider, with cost tracking, rate limiting, and tenant-level budgets. Important for businesses adopting AI without writing per-provider integrations.
Moltbot — personal AI assistant with voice interaction. Optional, bleeding-edge.

For paid customers who want a complete automation + AI stack, BotZ (our automation brand) sits on top of these.

Contracts and security

Smaller categories but high-value when needed.

DocuSeal — e-signatures and PDF contracts. Replaces DocuSign, HelloSign.
Vaultwarden — Bitwarden-compatible password manager. Self-hosted credentials store. Replaces 1Password, LastPass for businesses who don’t want their team’s secrets sitting in a SaaS.
Cryptomator — file encryption layer. Use on top of any file storage to encrypt-at-rest with client-side keys.

E-commerce and Bitcoin payments

For businesses that sell, especially internationally.

WooCommerce — full e-commerce platform on WordPress. Mature, ecosystem, plugins for every payment processor. Replaces Shopify for businesses willing to host.
Prestashop — heavier e-commerce platform for larger product catalogs. Replaces Magento at the mid-market.
BTCPay Server — self-hosted Bitcoin and Lightning payment processor. No third-party custody, no per-transaction fees, no chargebacks. The only path to genuinely sovereign Bitcoin payment acceptance. Available in shared-node and dedicated-node configurations.

What’s not on this list

A few notable omissions, with reasons:

Mastodon / Lemmy / Matrix. Communications federations are legitimate projects but operationally heavier than most SMBs want.
Joplin / Standard Notes. Personal note-taking apps work well, but they’re for individuals more than businesses.
Mautic alternatives like Listmonk. Listmonk works but covers a smaller surface than Mautic. Pick Mautic unless you only need newsletter sending.
Discourse. Community forum software. Good but only for businesses building a community as a product surface.

We add to this catalog as new apps prove themselves in production. The bar isn’t “does it have a GitHub repo” — it’s “does it actually work for paying customers, and can we maintain it operationally without breaking ourselves.”

How to use this list

If you’re considering moving off a SaaS stack:

Pick one category to start. Usually the most expensive line — CRM, marketing automation, support, or e-commerce.
Compare your current SaaS line item to its self-hosted equivalent. The math almost always favors hosting past about 10–15 employees.
Plan the migration. Most apps on this list have export tools from major SaaS competitors. Migration is a project, not a leap of faith.
Decide whether you’re hosting yourself or using AppZ. Self-hosting is fine for technical teams; AppZ is the path if you want the apps without operating the cluster.

Each app on this list has its own deployment, configuration, and operational requirements. Running 5 of them at once on your own infrastructure is achievable; running 15 isn’t, unless you have a dedicated platform team.

AppZ is the founding-cohort offering for that. The platform is live, the catalog is curated, and Founding Members are how the first deployments roll out.
