Should you switch to AYAstorm?
A side-by-side comparison of AYAstorm, Firestorm, Singularity, and Alchemy — drawn from official wikis, GitHub releases, community testing, and the LL Third-Party Viewer Directory. Use the controls below to compare features, score viewers across eight metrics, and read the technical deltas that set AYAstorm apart from base Firestorm.
Overall ranking (composite score)
weighted average of 8 metricsAt a glance
- ●AYAstorm wins on photography/rendering depth. Heavy Firestorm fork with novel post-FX.
- ●Firestorm is the safe default — biggest community, most features, official TPV status.
- ●Alchemy is the smoothest performer; no RLV is its main limitation.
- ●Singularity is the V1.23-style legacy choice; lacks PBR and WebRTC.

What AYAstorm adds on top of Firestorm
AYAstorm forks Firestorm 7.2.4 and layers in rendering controls, post-processing, niche fixes, and Japanese-language UX. Below are the technical deltas — every item below is in AYAstorm and not in stock Firestorm.
What you trade away
- ●TPV directory status — not yet on the official LL list; gray area for compliance.
- ●macOS support — Windows + Linux only as of r31.
- ●Single-maintainer risk — bus factor of ~1 (vs Firestorm’s team of dozens).
- ●Update cadence stability — r-series releases are frequent but smaller in scope.
- ●Community help — Firestorm has wiki, in-world groups, classes. AYAstorm has X + GitHub.
The AYAstorm Controls floater (Alt+C)
AYAstorm exposes 11 rendering category tabs in a single floater — these settings exist in Firestorm only as buried debug values, if at all.
Should you switch to AYAstorm?
Yes, switch — if you’re a virtual photographer, machinima creator, or visual tinkerer. AYAstorm is the only viewer in this comparison with selectable tone mappers, .cube LUT loading, SSS, motion blur, SSR, godrays, and the hair/foliage alpha glitch fix. It inherits Firestorm’s full feature set (PBR, WebRTC, RLV, Bridge, Phototools, Poser) so you give up almost nothing on the daily-driver side.
Stick with Firestorm if you need macOS, rely on the LL TPV Directory status for compliance, or want a viewer with a large support community and slow-changing release cadence. Try Alchemy if FPS smoothness is your top priority and you don’t need RLV. Avoid Singularity on the main SL grid in 2026 — no PBR and no WebRTC voice means it’ll degrade as LL sunsets Vivox.
Switch to AYAstorm if…
- • You take SL photos / machinima frequently
- • You want cinematic tone mapping / LUTs
- • Hair alpha glitches drive you crazy
- • You like tinkering with debug settings (Alt+C)
- • You’re on Windows or Linux
- • You read/write Japanese in-world
Stick with Firestorm if…
- • You’re on macOS
- • You need TPV directory compliance
- • Stability > bleeding-edge features
- • You rely on the FS in-world support group
- • You run on older hardware (use the legacy build)
- • You don’t care about post-FX
Try Alchemy if…
- • Raw FPS is your #1 priority
- • You don’t use RLV / RLVa
- • You want the latest LL code merged fast
- • You like a polished modern dark UI
- • Region tracking matters to you
Recommendation by use case
| Use case | Primary pick | Reasoning |
|---|---|---|
| Daily driver, general SL use | Firestorm | Broadest feature parity, biggest community, fastest LL fix uptake |
| SL photography / machinima | AYAstorm | Tone mappers, LUTs, SSS, DoF, alpha fix — none of the others have these |
| FPS-constrained / older hardware | Alchemy or Firestorm (legacy build) | Alchemy reported smoother; FS has two builds tuned by hardware age |
| Roleplay / RLV-dependent | Firestorm or AYAstorm | Both support RLV/RLVa; Alchemy does not |
| OpenSim / legacy grids | Singularity | Multi-grid login, free temp upload, V1.23 UI familiar to OpenSim residents |
| Performance hunter / latest LL features | Alchemy | Tracks LL release code most closely; performance-first philosophy |
| macOS user | Firestorm | Only viewer here with a current, stable Mac build |
| Japanese-language user on Linux | AYAstorm | Fixes the IME candidate-window bug + bundled JP fonts |

Download
You can get a copy at GitHub. (This link will age out – dig around to find the current release) There are versions for; Windows, Mac, and Linux. Scroll down the page to find the download links.
Performance
I didn’t get into my usual testing. I did notice as I took the shots above that Firestorm was running 17FPS and AYAstorm was making 29 FPS.
Also, you can see AYAstorm is darker than Firestorm. I have yet to sort that out. I assume the improved render process is the why.
Summary
I am going to be using AYAstorm to see how I like it. Generally I use the Firestorm Preview (Beta) viewer.
