Chatwoot
Omnichannel support desk with documented Application, Platform and Client APIs; MIT core, env-configured.
Community (self-hosted) · Cloud · Enterprise (self-hosted)
- I want WhatsApp, email and website chat in one queue on our own server and our agent drafting replies through the API
- I am paying per seat for Intercom or Zendesk and want a flat self-hosted desk
4 more jobs are undetermined.
- Platform API is self-hosted or managed hosting only, not cloud
- enterprise/ directory (Captain and others) is commercially licensed; MIT covers the core
- README warns of breakages if channel env vars are not set
- 1,300+ open issues: large surface, expect rough edges
Frappe Helpdesk
AGPL ticketing with agent and customer portals, SLAs, assignment rules and a knowledge base, all reachable over the Frappe REST API.
Self-hosted · Frappe Cloud
- I want a support desk with SLAs and a customer portal on our own server, no per-agent fees
- I already run Frappe apps and want tickets in the same bench
- Customer portal self-service
- Same bench footprint as Frappe CRM (MariaDB, Redis, Node, Python)
- AGPL-3.0
- DocType names above (HD Ticket, HD Article, HD Canned Response) are from the app's data model; verify field names against your version
Request Tracker
Enterprise ticket tracker with a Builder-shipped MCP server for search, create, reply, and update.
Free (self-hosted) · Cloud Starter: $15 per user/month, annual, 5-user minimum · Cloud Business: $29 per user/month, annual, 10-user minimum · Cloud Growth: $39 per user/month, annual
- we run a shared support or IT queue by email and want tickets triaged, assigned, and answered from our agent without leaving RT's audit trail
- we already have an RT instance and want Claude or Cursor to search TicketSQL and draft replies as a named user
- Dashboards, charts, and reports
- Track assets (RT Assets)
- Configure scrips and automation
- Knowledge base articles
- MCP server needs RT 6.0+ with REST 2.0 enabled; older RT 4.x/5.x installs must upgrade first
- Everything the agent does is logged as the token's user, including emails sent on replies; a repeated add_reply sends mail again
- Perl stack with a long CPAN dependency install; SELinux default blocks /opt/rt6
- GPL-2.0 copyleft on both RT and the MCP server
Zammad
AGPL helpdesk with a documented REST API for tickets, users, organizations and the knowledge base.
Community (self-hosted) · Hosted
- I need a proper ticket queue with SLAs for a small support team and want it on our own server
- I want our agent to triage and answer tickets through a stable REST API
3 more jobs are undetermined.
- Needs Elasticsearch for search; the compose stack runs five services
- AGPL: modifications to a hosted copy must be published
- Hosted edition has no free plan; only self-host is free
osTicket
Widely deployed GPL support ticket system whose own API only creates tickets; MCP wrappers need a companion plugin.
Free (self-hosted) · SupportSystem (hosted)
- we need a plain email-to-ticket help desk that thousands of small teams already run and our own IT can host on PHP and MySQL
- we mostly need our agent to open tickets from other systems; reading and updating them is a nice-to-have we accept a plugin for
- Knowledge base and FAQ
- Help topics, SLAs, ticket filters
- Agents, teams, departments admin
- Customer self-service portal
1 more job is undetermined.
- Official API is creation-only; every read or update path needs a third-party plugin and wrapper
- Recommended wrapper has 1 star and depends on the NKS osTicket API plugin being installed
- Last push 2026-06-17, inside the window but the slowest of the support picks
- GPL-2.0 copyleft
Zoho Desk
Hosted help desk with a Free Forever edition for three agents and an official Zoho MCP server.
Free: Free · Express: ₹420 per user/month, annual (regional pricing shown at fetch) · Standard: ₹800 per user/month, annual · Professional: ₹1,400 per user/month, annual · Enterprise: ₹2,400 per user/month, annual
- we are a three-person team on Zoho's free plan and want our agent to triage and answer tickets without paying for a seat

- Configure SLAs and automation rules
- Handle chat, phone, and social channels
4 more jobs are undetermined.
- Whether the Free edition can use the MCP server is not stated; Zoho gates API and integration features by plan
- Pricing page served INR at fetch time; USD list prices differ
- No public tool list for the Desk MCP; Reach is inferred from one example prompt
