What changed recently

A sandbox you picked last quarter may not be the same product today. These are the dated changes the research found, newest first, with the source for each. Where a provider announced nothing and the change is only visible in an archive, the entry says so.

The record

An entry dated by observation says the change date is not published

Sprites

Sprites' rates are roughly half the figures still in circulation

Fly's current list is $0.0385 per CPU-hour and $0.021875 per GB-hour, both measured on actual use. A widely copied comparison still narrates $0.07 and $0.04375. Fly publishes no change date, so this entry is dated by observation, not by an announcement. The same pricing page says there are no plans, while the Sprites FAQ describes a plan ladder up to Mythic at $100 a month.

boxd

boxd cut its rates by about a fifth and doubled the machine quota in 19 days

The 9 October capture of boxd's pricing page lists €0.049 per vCPU-hour, €0.015 per GiB-hour of RAM, €0.0001 per GiB-hour of disk and 50 machines. The live page lists €0.039, €0.012, €0.00008 and 100 machines. boxd publishes no price-change notice, and its terms let it adjust rates at any time for usage from the date of the change.

Daytona

Daytona raised $60M at a $1B valuation

Daytona's Series B, led by FirstMark Growth, brings total funding to $91M. It is the same month the company's open-source repository was archived and core development moved to a private codebase.

InstaBox

InstaBox put a price on a product that was two weeks old

InstaBox launched on 14 October 2026 and published pricing five days later: $20, $100 and $500 plans that double as credit, plus a free plan with one 4 vCPU / 8 GiB machine. It is the second product from InsForge AI, whose first product is a backend platform.

“Today we're releasing InstaBox pricing.”

Runtime

Runtime changed its idle pause from one minute to five

A sandbox now pauses after 300 seconds with no request, command, connection, traffic or CPU use, where the default was 60 seconds. The changelog is the only announcement; the pricing page carries the current number.

“Idle sandboxes now pause after 5 minutes.”

InstaBox

InstaBox launched as a second product from InsForge

The sandbox product went public on 14 October 2026, about a year after the company was founded and seven months after its Y Combinator batch. The YC badge sits on insforge.dev, not on instabox.sh.

“Since we launched on Oct 14, beta users have been using InstaBox for free.”

Modal

Modal raised $750M and said Sandboxes alone runs at $300M

The Series D values Modal at $15.75B post-money and takes total funding over $1.2B. The same post says the company crossed $1B in annualized run rate and that Sandboxes is a $300M run-rate product on its own.

“we've raised a $750M Series D at a $15.75B post-money valuation. Accel led the round.”

Lizard

Lizard's sandboxes became Firecracker microVMs, and the meter became a flat price per size

On 30 September 2026 Lizard's own limits page said sandboxes ran in Kubernetes pods on a shared kernel at a fixed 4 vCPU / 4096 MiB, billed on measured CPU, memory, storage and egress. By 13 October the pricing page listed three sizes at a flat hourly rate. Neither page announced the change and there is no migration note. The billing model changed; no published figure shows that any bill went up.

“Sandboxes run short-lived commands and agent tasks in Kubernetes pods with the runc runtime. They share the host kernel; they are not Firecracker virtual machines.”

Boat

Box became Boat

The product launched as box in July 2026 and was renamed boat on 15 September 2026. Box endpoints still answer, with Deprecation and Sunset headers; the Sunset date is a warning, not a shutdown. The legal entity, Dedale AI, Corp., did not change.

“Box became boat on September 15, 2026.”

Blaxel

Baseten acquired Blaxel

Baseten announced the acquisition on 10 September 2026 and said the product continues unchanged, with new Baseten products to follow. Each Baseten organisation now maps to one Blaxel workspace. The standard terms linked from Blaxel's site are dated 10 December 2025 and still name Blaxel, Inc., so the contracting entity after the deal is worth confirming in writing.

“Baseten has acquired Blaxel.”

“Each Baseten organization maps to one dedicated Blaxel workspace and one dedicated Blaxel account.”

Cloudflare Sandbox

Cloudflare Containers and Sandboxes became generally available

The GA entry is in the changelog, not a marketing page. Two parts of the product are still in public beta: the Durable Object scheduling policy that sandboxes use, and container snapshots. The 1.0 helper library arrived on 30 September 2026, and the 0.x SDK gets fixes only until 31 December 2026.

“Cloudflare Containers and Sandboxes are now generally available.”
