Product and intent mapping
Tiden reads the codebase and records product components and specifications, including which promises do not yet have test coverage.
Tiden
Tiden verifies code written by coding agents against versioned product specifications, generated tests, and a quality gate. It is designed for engineering teams that want evidence that an agent implemented the requested behavior before changes are merged and released.
Intent verification for coding agents
Tiden is an intent-verification tool for engineering teams using coding agents. It reads a codebase, maps the product's components and specifications, and identifies promises that are not yet covered by tests. Those specifications are kept versioned beside the code rather than treated as a one-time planning document.
During an agent session, Tiden provides a working contract for the requested change. Generated tests and a quality gate connect the requested behavior to evidence: open promises keep a session from closing, and merged pull requests can receive a verified-change verdict. Release views and error tracking extend that record beyond code review so teams can see what was promised, what passed, and where production issues trace back to a release.
Core capabilities
Versioned specifications
Specifications remain versioned beside the code, and Tiden drafts an update on every merge, including merges that bypass Tiden.
Agent working contracts
Each agent session starts from a working contract of the requested behavior. A session cannot close while a promise remains open.
Generated tests and quality gate
Tiden links promises to generated tests and shows whether each test is running, passing, or still open before a change is merged.
Change and proof review
Branches show what changed, what the code was supposed to do, and which tests prove it, leaving review with the team's reviewer.
Release and error traceability
Release views provide a verdict by part, and production errors can be traced back to the release associated with the missing test or behavior.
Practical use cases
Controlling agent coding sessions
Give an agent a session-level contract for a feature, then keep the session open until the requested promises have corresponding test evidence.
Reviewing generated pull requests
Use branch and pull-request views to compare the requested behavior with the implementation and the tests that prove it before merging.
Keeping product intent synchronized
Maintain a current map of components, specifications, and test coverage across a product as code changes merge, including changes made outside Tiden.
Investigating release risk and errors
Inspect release coverage by product area and follow production errors back to the release and missing test associated with the behavior.
Pros and Cons
Pros
- Connects agent-written changes to explicit product specifications and test evidence.
- Keeps specifications versioned beside the code and updates the record on merges.
- Supports a workflow spanning agent sessions, pull-request review, releases, and production error tracing.
- Works alongside Claude Code, Cursor, Copilot, and Codex, with named connections for GitHub, Jira, Linear, Notion, and Azure DevOps.
Cons
- The available product material does not explain the full installation, session, repository, CI, or deployment workflow beyond the homepage summary and command-line installer.
- The quality model depends on promises being represented by tests; the site shows that uncovered behavior is flagged, but does not describe how every type of requirement is handled.
FAQ
How does Tiden verify agent-written code?
Tiden reads the codebase, maps product components and specifications, and keeps specifications versioned beside the code. Coding agents then start sessions from that working contract, while tests and a quality gate verify the promises made by a change.
How do I get started with Tiden?
The homepage shows a command-line installation using `curl -fsSL https://tiden.ai/install.sh | bash`. The site does not provide more detailed setup instructions in the available material.
Which coding agents and tools does Tiden support?
Tiden is shown working beside Claude Code, Cursor, Copilot, and Codex. The homepage also names GitHub, Jira, Linear, Notion, and Azure DevOps as connected tools, although the available content does not specify the exact integration workflow for each.
What counts as a verified change?
A verified change is a pull request that merges with a passing quality gate. It is billed once regardless of the number of runs; retries, failed changes, and bot commits are free.
Is there a free trial?
Yes. The pricing page offers 14-day free trials on Starter and Team. Billing begins on day 15 if the plan is retained.

Alternatives à Tiden
ByteAsk
ByteAsk is a terminal-first AI coding agent for C and C++ that edits repositories and verifies changes with the real compiler, debugger, sanitizers, and tests before showing a diff. It offers a free tier plus paid plans, with editor connectors and zero-retention handling described in the source.
Manta AI
Manta AI is an autonomous web app testing tool for teams that want to map application behavior, catch regressions, and generate tests without writing scripts or maintaining selectors. It works from a URL and supports plain-English test flows, run results with screenshots, and scheduled or deployment-triggered checks.
Epherem
Epherem is a static security scanner for web apps built with AI coding tools such as Lovable, Bolt, v0, Replit, Cursor, and Claude Code. It checks source files and dependencies for common security mistakes, then provides categorized findings and suggested fixes without running the app.
CreateOS Sandbox
CreateOS Sandbox is an isolated compute environment for running code and agent workloads inside Firecracker micro-VMs. It is designed for workflows that need machine-level isolation, private networking between sandboxes, and programmatic control through SDK, CLI, or MCP.
GitBot
GitBot is a local browser-based workspace for creating reusable coding bots powered by Claude Code, Codex, or OpenCode. It helps developers run those agents across repository folders with persistent threads and configurable permissions.
hob
hob is an independent workspace for coding agents that keeps agent sessions, terminals, history, and follow-up work organized around the tools and providers you already use. It is aimed at developers who want local control over routing, history, and workspace structure rather than a bundled model stack.
