Your servers. Your database. AI on your own API key. One flat price per instance.
Your servers. Your key. One flat price.
Annual cost for a 25-person team, at published list prices.
Self-hosted buyers are cornered. Jira Data Center is retired in March 2029, Linear has never shipped a self-hosted build, and YouTrack ended perpetual licences in 2026. Mertis is the modern tracker that still installs on hardware you control.
Published list prices, checked September 2026: Linear Business $16/user/mo billed annually · Jira Cloud Standard ≈ $7.91/user/mo · YouTrack Cloud $4.50/user/mo billed annually. Mertis Professional is $790/yr for the instance, up to its 500-user licence cap.
Tap a card for the detail. The free edition caps size and holds back the premium features; the whole triage workflow is there.
Tap a card for detail.
Assignee, reporter, QA owner — and who it's blocked on.
Severity, priority, type and status on every record, plus an Action-Required-By field so a bug always names the person it is waiting on. Per-project IDs keep references readable across teams.
Engineers see their bugs. Admins see everything.
Three roles — user, admin, godmode. A user only sees bugs they own, reported, QA, or are blocking, so the security backlog is never exposed by accident.
Every change and comment, with actor and timestamp.
Field-level history on every bug, attachments carrying provenance, and an export you can hand an auditor without a support ticket.
Project health, ageing criticals, load per owner.
Role-aware, so an engineer's dashboard isn't the VP's dashboard. Open-vs-resolved trend, severity mix and per-project drill-down out of the box.
Charts plus written commentary, on a schedule.
Generated on demand or mailed on a schedule through your own SMTP relay, from your own domain. Board packs stop being a Monday-morning chore.
Sanitised HTML, inline images, attachments that scale.
Attachments land on local disk, S3, Azure Blob, SharePoint or Supabase — chosen per deployment. Community and Team are capped at 5 MB and 25 MB; S3 starts at Team and the remaining backends at Professional.
Nobody remembers ticket IDs. Search the way the bug was actually reported — in a sentence — and Mertis returns the matching defects and the near-duplicates you were about to file again.
Runs on your own API key or a local model, on your server — the query and the bug text never leave your network. Professional
Every other tracker's AI ships your defect history to their cloud. Mertis calls the model from your server, with your key.
Your server. Your key. No credits.

No marketplace to browse, no per-connector billing.
Commits link themselves to bugs.
Mention SM-0147 in a commit message and the bug picks up the reference, the author and a diff link on its timeline.
Two-way board sync.
A card moves and the bug status follows; a new bug can spawn a card on the right list. Mapped per project, with its own dashboard.
HMAC-signed outbound events.
Push bug events into your warehouse, a Slack relay or an internal service. One endpoint on Community, three on Team, unlimited from Professional.
One file, not a fork.
Drop a file into server/plugins/ and the loader picks it up. Most "can it integrate with X?" answers are a plugin, not a code change.
Everything the UI can do.
Bugs, projects, users, analytics and attachments over JWT-authenticated REST. Read-only on Community, full access from Team upward.
Your relay, your domain. Pro
Scheduled reports leave from your own mail server with your DKIM — no third-party sender in the middle of your bug traffic. Scheduled email is a Professional feature and needs MySQL or PostgreSQL, not CSV mode.
One URL for monitoring.
/api/health reports storage type, database connection and file providers — wire it straight into your existing monitoring.
On every plan, including free.
An admin downloads the instance as JSON, or one project's bugs as CSV, from Admin or the bug list. Same on MySQL, PostgreSQL and CSV. It is not a paid feature.
Chosen by environment variable, changed from the admin UI — application code never knows.
DATABASE_PROVIDER=auto
DEFAULT_STORAGE=s3
Free key, issued instantly.
npm run dev, Node 16+.
DB, storage, admin account.
Paste the key. Verified offline.
Install on your own server, VPS or on-prem hardware. You keep the database, the buckets and the model keys.
We host, patch, monitor and back it up. Not launched yet — the waitlist is open and shapes what ships first.
Bugs never leave your servers.
Instance JSON or project CSV, including free.
14-day grace, then data stays editable.
Licences verify offline. One daily renewal check, switchable off.
Most vendors sell independence as the expensive plan. Every claim below is true on the free tier, and every one has a check you can run yourself.
True on the free tier. Each one has a check you can run yourself.
Take the machine offline and restart. Mertis comes up on the same tier, because the licence is an ES256 token checked against a public key compiled into the build. Verification never touches the internet.
Paste a signed token at setup instead of a key. That install makes no outbound request, on any day, for any reason.
An install activated with a TT- key asks once a day whether its expiry has moved. Set LICENSE_AUTO_REFRESH=false and even that stops. Nothing else changes.
DATABASE_PROVIDER=csv keeps every bug as plain CSV under server/data, readable with cat. Point it at MySQL or PostgreSQL and it is your instance, your backups, your region.
OPENAI_BASE_URL points the AI features at a model running on your own hardware. Leave the key unset and there is no AI call to make. Your bug text is never ours to see.
None of this is a tier. It is how the free Community Edition already behaves, and how the paid plans behave too.
Mertis ships under the Business Source License 1.1. You can read the code, patch it and run it. It is not OSI open source, and we will not call it that.
BSL 1.1. Read it, patch it, run it. Not OSI open source.
Every line that runs on your server is readable. Audit it, patch it, fork it for your own use. What you may not do is remove the licence checks or resell it as a hosted service.
Community Edition is free in production forever within its limits: 5 users, 3 projects, 250 bugs per instance. No expiry, no card, no feature clock running down.
Four years after a version is published it converts to the Apache License 2.0 automatically. The licence is a delay, not a cage, and that conversion is written into the file rather than promised in a blog post.
Mertis is an independent React 18 and Node codebase with its own licensing, AI layer and integrations. Different code, different licence, different company.
Self-hosted is priced per running instance. Managed Cloud is the only per-seat product.
$1,490/yr — 10 client instances, one master licence.
Pricing →Unlimited instances, SLA, PO billing.
Talk to us →Air-gapped, private LLM, compliance pack.
Talk to us →We host it. Per seat, not yet launched.
Waitlist →Professional is capped at 500 users and Business at 2,000 — the caps are written into the licence, and no legitimate team gets close. INR list prices apply to Indian customers. There is no self-serve checkout yet: every purchase is invoiced directly by Turnera Tech, so talk to sales for payment methods and tax handling. Prices exclude applicable taxes.

A 14-day grace period with an in-app banner. After that, premium features switch off and Community limits apply to newly created objects only. Every existing bug stays readable, editable and exportable. We do not lock data behind a renewal.
No telemetry, no usage data, no analytics — ever. Licence keys are ES256-signed JWTs verified locally against a public key compiled into the build, so verification never needs the network and an air-gapped install works out of the box. There is exactly one outbound call: an install activated with a TT- key re-checks once a day for a renewed expiry, sending its licence key and install ID and nothing else. Activate with an offline token and Mertis never calls out at all. Switch the daily check off with LICENSE_AUTO_REFRESH=false — the licence then expires rather than renewing.
Not on self-hosted. Community, Team, Professional, Business and Agency are priced per instance. Managed Cloud is per seat, because we carry the hosting cost there.
On your server, calling the model with your own API key. Turnera Tech sees neither prompt nor response. Point OPENAI_BASE_URL at an internal vLLM, Azure OpenAI or Ollama endpoint and nothing leaves your network.
Yes — a fixed-fee service, typically up to 50,000 issues including attachments and history mapping. Send sales an export sample and we'll scope it before you commit.
Yes — the INR list prices above are what Indian customers pay. Self-serve checkout is still being built, so purchases are invoiced directly by Turnera Tech at the moment; sales will confirm payment methods and tax handling when you order.
Run it on a laptop this afternoon. Decide with real data in it.
