Tools for tracking A/B tests

The problem, in plain words: “I need a single place to track and manage A/B tests across multiple clients, including hypotheses, status, results, and learnings, without running the tests themselves.”

Productive fits best.

You want a shared, multi-client workspace to log hypotheses, track experiment status and results, capture learnings, and share reports — without the tool running experiments.

Updated August 2026.

What fits

Productivestrong · 86

Built specifically for agencies, it centralizes projects, client workspaces, documentation and reporting so you can record hypotheses, track status, store results and publish learnings per client under one login.

Best for: Agencies, consultancies or teams managing experiments across multiple clients who need client-level visibility, reporting and resource/project controls.

Caveat: An account is required before use.

Partly fits

Client Portal Managerpartial · 68

Provides a single portal per client for document sharing, tasks and communication, so you can store hypotheses, statuses and learnings in client-facing spaces.

Won’t cover: Targeted at freelancers and very small agencies, so it may be narrower than what a multi-client agency team needs.

ClientSignalpartial · 56

Automates white-labelled client reporting from analytics sources, which helps share experiment results and recommendations across multiple clients without running tests.

Won’t cover: Focused on automated campaign and analytics reports rather than a structured, editable experiment log with hypothesis and learning fields.

Client Notespartial · 50

Provides per-client timelines, tagged notes, reminders and exports that could be repurposed to record experiment hypotheses, status updates and learnings for individual clients.

Won’t cover: Stores data on the device and is designed as a single-user app, so it lacks a shared cloud workspace for cross-team, multi-client collaboration.

ClienTrak: Client Notes & CRMpartial · 48

Timestamped client notes, status tracking and PDF exports let you document experiments and produce client-facing reports from a single place on a mobile device.

Won’t cover: Designed as an iPhone-first personal note/CRM with local data storage, so it does not provide a multi-user, multi-client cloud workspace for agency teams.
