Three tools in the catalogue have a recorded founding year of 2024 or later, as of 2026-09-24. All three years are vendor-stated. No tool has a recorded founding year of 2025 or 2026.
This is a short list because the founding year is recorded for 43 of 330 tools. The other 287 tools have no recorded founding year, so this post cannot say whether they started before or after 2024.
2024
The table is sorted by tool name, A to Z.
| Tool | Vendor | Category | Founded | Evidence | Verified on |
|---|---|---|---|---|---|
| Browser Use | Browser Use | MCP servers for testing | 2024 | vendor-stated | 2026-09-24 |
| DevAssure | DevAssure Inc. | Agentic end-to-end testing | 2024 | vendor-stated | 2026-09-24 |
| Thunders | Thunders | Natural-language test authoring | 2024 | vendor-stated | 2026-09-24 |
Each year comes from the vendor's own website, not from documentation or a public record. That is why each is labelled vendor-stated.

Founding years across the catalogue
The founded fact is recorded for 43 tools. Of these, 5 years are documented and 38 are vendor-stated. By period:
| Founded | Tools |
|---|---|
| Before 2010 | 13 |
| 2010 to 2019 | 20 |
| 2020 to 2023 | 7 |
| 2024 or later | 3 |
Three tools have a founding year of 2023, just before the cut-off for this post. CodeRabbit and QA Sphere give 2023 as vendor-stated. Testkube gives 2023 as documented.
Tools with no recorded founding year
287 of 330 tools have no recorded founding year. They fall into two groups:
- 90 tools: the founding year was looked for and not found on any public page, so the fact is not documented.
- 197 tools: no founding year is recorded in the catalogue.
We do not infer founding years. A year appears only when a public page states it. A tool without a recorded year may have started in 2024 or later.
What the founding year refers to
The year is the one the cited page states. For the three tools above, that page is the vendor's own site. A vendor's founding year can differ from the release year of its testing product. A vendor founded before 2024 can still have a testing product first released in 2024 or later.
The status page records dated launches, acquisitions, renames and shutdowns. The tool index lists all 330 tools. Our methodology explains evidence levels and how facts are checked.
