Why we built Tesbo

AI takes the grind.
QA keeps the judgment.

Test design demands critical thinking and analysis. Tesbo's agent drafts the cases, steps, and reports. Nothing enters your suite until you approve it.

A test case management system, with an AI agent inside it

Every test your team runs, in one place: organised, versioned, traceable, and drafted for you.

QA engineers

Spend the week designing tests, not typing them

The agent writes the cases, steps, and bug reports. You review and decide.

QA managers

Answer “what’s covered?” without asking anyone

One repository shows what's tested, what's risky, and what to automate next.

Founders and CTOs

Make the release call on evidence

See coverage and pass rates before you ship, instead of asking if everyone feels good about it.

01The foundation

Automation is racing ahead. Most teams skipped the foundation.

Automation only pays off on top of something measured. You can't automate what you can't see.

Test case management is that foundation.

You can't automate what you can't see

A managed repository shows your real coverage and the gaps.

Decide what to automate, and what to skip

Priorities and run history make automation a deliberate call.

That's how automation earns its ROI

Speed and coverage compound only on a measured base.

02The evidence

Your best QA engineers spend the week on work that doesn't need them

Test design is analysis. Typing steps, copying data, and chasing statuses crowd it out.

03What we believe

Three things we're sure about

01The mission

The more AI writes, the more judgment matters

Someone must define what 'working' means.

Code volume is exploding. The scarce skill is deciding what to test and when it's safe to ship.

02The craft

Test design is a craft, not clerical work

It deserves an engineer's full attention.

Imagining how a product fails takes product sense, analysis, and creativity.

03The division

AI should carry the grind, not the judgment

Delegate the mechanics. Keep every decision human.

Machines are better at drafting steps, filling fields, and filing bugs.

04Who does what

The AI era playbook: delegate the grind, keep the judgment

Hand the mechanical work to an agent that never tires. Every hour it returns is leverage, and nothing lands without a reviewer's sign-off.

QA becomes the center of quality: deciding what gets tested, guiding the agents, and making the release call.

Hand off to AI

Drafting cases from a story or spec

Writing steps and expected results

Filing bugs from failed runs

Syncing tickets from Jira or Linear

Keeping statuses and coverage current

Hold on to these

Deciding what's worth testing

Exploratory testing no script would find

Approving everything the AI drafts

Judging release readiness

Owning the quality bar

05What it means for the product

Give QA their thinking back, and quality is what feels the difference

This isn't about tooling. QA becomes the reviewer and the monitor, holding actual results against expected, and the quality numbers move.

Drag the handle to compare. Same team, same week.

Without Tesbo

Coverage unknown

Week lost to data entry

Feedback arrives late

Release call on gut feel

With Tesbo

Coverage measured, gaps visible

So we built Tesbo

Every part carries the grind, so you can carry the thinking

Tesbo's AI knows your product, a human always signs off, and the whole system is open to every team.

(01)Zyra AI

An AI that already knows your product

Zyra turns a user story into a full set of test cases, grounded in a RAG-indexed knowledge base of your real product context, not generic guesswork. Every draft is queued for your approval.

Generates cases from a story, spec, or KB doc

Writes steps, preconditions, and expected results

Answers questions grounded in your project knowledge

app.tesbo.dev · Zyra

(02)Human in the loop

Nothing ships without a reviewer's sign-off

Every AI-drafted case, patch, and bug waits in a review queue. The engineer approves, edits, or rejects. The machine does the typing and the human keeps the judgment.

Review queue for all AI-generated content

Approve, edit, or reject in one place

Full audit trail of who or what changed what

app.tesbo.dev · Review queue

Nothing ships without a reviewer's sign-off

(03)Test repository

A real system of record for your tests

Organize hundreds of cases into nested suites with priorities, steps, and rich detail. Group them into runs, assign testers, and record results. No more spreadsheets, full history and traceability.

Nested suites, priorities, and rich steps

Plans, runs, and per-case results

Traceability into Jira and Linear

(04)Reports

Answer the only question that matters: are we ready to ship?

Pass rates, flaky-test detection, coverage gaps, and an AI health score across every run. The release call rests on evidence, made by the person who owns quality.

Everything QA needs

One workspace for the whole test cycle

From authoring cases to running them, tracking bugs, and reporting, with an AI agent working alongside your team the entire way.

Test case repository

Organize hundreds of cases into nested suites with priorities, steps, and rich descriptions. Bulk edit, import, and export via CSV or XLSX.

Test runs & executions

Group cases into plans and runs, assign testers, and record per-case results. Schedule recurring runs and share public read-only links.

Zyra AI generation

Turn a user story into a complete set of drafted cases in seconds, then queue them for human review before they enter the repository.

Bug & defect tracking

File bugs from failed executions automatically, attach evidence, and reference external trackers, all linked back to the failing case.

Requirements traceability

Import requirements from Jira and Linear, map them to cases, and see coverage roll up across every run in the traceability matrix.

Knowledge base + RAG

Hierarchical docs and files, versioned and vector-indexed, power semantic retrieval so Zyra answers grounded in your project's context.

Tesbo MCP server

Connect any AI agent, like Claude, Cursor, or your own, directly to Tesbo over MCP, under the same human-approval rules as Zyra.

Deep analytics

A full picture of QA health: trends across releases, risk hotspots, and AI-surfaced insights on what's actually likely to break next.

Detailed audit logs

Every action, by AI agent or human, is logged in full. An enterprise-grade trail of exactly who or what changed what, and when.

Open source · Apache 2.0

A foundation this important shouldn't sit behind a paywall. So it's open source

Tesbo is fully open source under the Apache 2.0 license and self-hostable anywhere Docker runs. Any team, funded or not, can adopt the foundation and own their data.

Apache 2.0 licensed

Fork it, extend it, ship it. No core features sit behind a paid tier.

Self-host anywhere

One Docker compose file runs it on a laptop, a VPS, or your own cluster.

Your data never leaves

Self-hosted database and RAG index. Nothing phones home.

Adoptable by any team

No per-seat pricing, so cost never decides who gets a foundation.

Two commands. Up in minutes.
