Fiuto

Fiuto is a user research tool that runs the full research loop. It drafts a study around a product and its audience from a URL or a description, runs it with AI testers first and then with real people recruited from Prolific's panel of 300,000+ participants or the team's own users, and turns the results into findings, a readout, and a shareable deck. Eighteen research methods, including five-second, first-click, card sort, tree test, preference test, survey, and live-site tasks, are available on every plan. Studies can be created and read back from the web app or over MCP from coding agents such as Claude Code, Cursor, Codex, Lovable, v0, Replit, and Bolt. Results export as CSV or JSON through a per-study API token. Pricing is per account with unlimited viewers; there are no seats.

EventSend

My Tiny Rocket LLC

EventSend is event tracking and alert routing for a small SaaS team - the two halves of knowing what your product is doing. Send an event with one HTTP POST from any language, or write no code at all: paste one URL into Stripe, GitHub or Vercel and their webhooks arrive formatted and deduplicated. Every event lands in a live feed you can search and filter by name, level, source, customer and date, with operational analytics over it: volume, error rate, delivery health per destination, and twelve months of history on every plan. Filter to one customer and you have their timeline. Then rules route the events that matter to where your team already is: Slack, Discord, Telegram, a signed webhook, or a push notification on your phone, with retries and backoff, circuit breakers around a failing destination, and a log of every attempt. Your AI assistant can read the same history and tell you what happened. Free forever for 2,500 events a month, plans from $12.

Mentcube Innovations Pvt Ltd

Zunoy Sandbox is a developer testing platform for testing email, SMS, webhooks, OTP, and TOTP/MFA flows without sending test data to real users or production systems.

Clearlane Tests

Clearlane Apps

Clearlane Tests adds test management to Jira Cloud without new work item types. Versioned test cases store steps, test data and expected results, and link to the requirement work items they cover. A coverage view acts as a requirements traceability matrix and identifies requirements with no test case. Plan a campaign for each version or sprint, then run tests step by step. Each run records the exact test case version, pass/fail results and comments for each step, plus the tester and date. A failed step becomes a Jira bug with reproduction steps in one click. Closing a campaign seals it with a fingerprint. Optional electronic signatures record the name, date and time, and meaning; later changes void the signatures. PDF reports include the summary, coverage, results and history. Import test cases from CSV. The app helps teams maintain verification records for IEC 62304, ISO 13485 and 21 CFR Part 11. It runs on Atlassian Forge, so data stays in the customer's Atlassian site.

specgit

FnFirst

specgit is a visual editor for teams writing together in GitHub. It handles Git so product managers, UX researchers, technical writers, and teammates can write and format docs as they would in a document editor. Each save becomes a commit under the writer's GitHub name. Teammates can edit the same file live and leave inline comments. When a doc is ready, specgit opens a pull request for engineers to review in GitHub. Review reads the whole doc and leaves comments; Triage fixes them and closes the threads. Nothing changes until you approve it. Teams can also use specgit with Obsidian vaults; saved files retain Obsidian's exact format. GitHub remains the source of truth, and specgit does not keep copies of documents or comments. The Free plan includes one repository and five publishes per month, with no credit card required. Pro costs $8 per editing seat per month; viewing and commenting are always free.
